Digital Audio – BMW 1 Series

It used to be so easy if we wanted a better sound in our car. Change the factory fitted radio, upgrade the speakers and maybe add an amplifier and sub.

I can’t remember how many of these Audi A3s I’ve done over the years, it must be hundreds.
But what about the modern version?

This car infotainment system has satellite navigation and integration with the vehicle systems; not to mention a full fibre optic audio path with multi-channel amplification and 11 speakers. The specification is very impressive but unfortunately the audio performance is less than satisfactory. The Bose and B&O ‘upgrades’ are particularly poor with weak bass and a flat sounding front end.

The same applies to BMW, Mercedes, Porsche, Mini, Jaguar and others. It is just not possible to change the front end systems and all these manufacturers use a sophisticated fibre optic system or MOST ring for audio. This system is not compatible with aftermarket amplifiers so what do we do to improve the audio in these cars?

Let’s take the BMW 1 Series with Harman Kardon audio as an example.

The BMW 1 Series is a great car, but in my opinion has one of the worst sounding audio systems out there. Naturally we can replace the speakers with the likes of Eton or Rainbow; that will make it sound better but we haven’t addressed the real problem of the HK amplifier. This amplifier has been designed for a specific purpose; to make the stock BMW speakers sound OK while protecting them from overzealous use of the bass control. You may have noticed that when you try to turn up the bass the sound gets muddy sounding. This is because the amplifier is not turning up the bass, but instead is turning down the treble.

No, if we want a great sounding audio system this amplifier has to go. But what about the MOST ring and all the chimes, tones and announcements generated by the car, won’t we lose them? What we need is a device that can read the signals on the MOST ring and interpret the different information streams separating out the audio from the vehicle data. This device must be able to play the different vehicle announcements exactly as the makers intended while providing a clean digital audio signal. Ideally it should be programmable so that updates and even different vehicle configurations can be accommodated without the need to change the interface. It should also be capable of being invisible to diagnostic tools to prevent device errors.

So all in all we need a pretty sophisticated device; step forward the Audison Bit DMI.

This unassuming little box is our saviour as it converts the MOST signal to standard digital optical. The really clever part is that it can be reprogrammed indefinitely. The clever engineers at Audison have cracked the code for different car manufacturers which means that we can connect this and be confident that all the original systems will be played perfectly.

Now we have a digital optical signal that contains the audio signal as well as all the chimes and announcements from the vehicle park assist, satellite navigation and bluetooth modules. Now we can start adding the amplifiers that will complement the upgraded speakers confident that they can perform as intended.

In fact this is one of my most common system packages for the BMW 1 and 3 series. The Bit DMI replaces the factory amplifier and converts the MOST signal. The optical stream is then fed to the Audison AP8.9 Bit amplifier. This amp features up to 8 channels of high power output as well as a full spectrum digital audio processor allowing total control over every speaker. I configure it as a 6 channel to drive the door and under seat speakers as a fully active component set. My favourite choice of speaker is the Eton Upgrade system. These German built speakers are fabulous and offer a performance level well above anything else on the market currently. The AP 1D slave amplifier is to run the Audison APBX8 slim sub enclosure in the boot.

The Result?

The difference between the BMW ‘upgrade’ audio and the Audison/Eton one is incredible. The bass has far better definition while the front sound stage is clear and totally immersive. Gone are the harsh high frequencies of the Harman Kardon speakers to be replaced with a smooth and sensitive full range sound. Of course a lot of it is down to how I tune the car but that just means that every customer can get exactly what they want.

The same or similar systems can be applied to Porsche, Audi, Aston Martin, Mercedes and others; with just a change of speakers to suit the car. That is not to say that we have a ‘one size fits all’ approach. On the contrary, we look at each installation individually to make sure that each customer gets a bespoke solution. After all, everyone is different; that is where my tuning skills come into play to make sure every car is optimised for the biggest smile!

Porsche Boxster Audio Upgrade.

The Porsche Boxster S is a superb car which offers exciting top-down performance with practical everyday driving capability. Unfortunately, the audio performance leaves an awful lot to be desired especially the base version that is only equipped with dash speakers.

porsche boxster speakers

The biggest challenge, of course, is the convertible top because as soon as that is raised most of the sound and pretty much all the bass disappears. Car audio in a Porsche for some owners is not a priority but for this customer, the lack of a decent sound was spoiling the drive so an appointment was made to discuss options.

Step One:

The first choice to make was whether the original head unit was to be changed. It is completely possible for us to use any original factory unit as a base for great audio but in this case, the basic Becker unit was certainly past its best so a decision to upgrade to a top of the range Pioneer unit was made.

The Pioneer AVIC F88DAB is a full house unit boasting a 7-inch screen, full satellite navigation, DVD, CD, SD, Bluetooth, dual USB, DAB radio, Apple Car Play and Android Auto. Its comprehensive external connections make it ideal for use as a high-performance head unit in a sophisticated audio system. It also boasts a very powerful set of audio controls to allow accurate tuning of the system.

Installing this double din unit means relocating the heater controls to the lower console. We use an American kit that costs a little more than others but is of a far superior quality with a factory standard fit and finish.

Once we had relocated all the standard wiring and removed the remnants of an old ‘phone kit we could start the new wiring. When we install new looms we always wrap them in OE quality fleece tape, this ensures a factory look but most importantly eliminates any possibility of cable rattles. Where cables go through the bulkhead grommets we make sure to use silicone sealant to prevent any water ingress.

What next?

Once the looms had been installed we could start the hardware installation, first was the amplifier. Originally this Boxster had a CD changer mounted in the bonnet just behind the spare wheel; since this would be useless with the new head unit we removed it to locate the Hertz DPower 4 amplifier.

Hertz D Power 4 amplifier.

This amplifier is an absolute gem with over 100W per channel on tap it is perfect to drive the dash speakers and subwoofer. Although it is well equipped with filters to tune the system we will use the crossovers and EQ available on the Pioneer F88 to really fine tune the final sound. Again more cloth tape keeps everything neat.

Once the amplifier was in we could install the dash speakers. The dash location allows for a separate mid and tweeter under the original grille. However, as there was only to be a single channel input per side there was no advantage to splitting the drivers up and so we chose the Audison APX4 coaxial speakers.

This speaker really is surprisingly good.

At only 4 inch diameter it is capable of a really good bass response and when powered by a good amplifier it delivers a very accurate and responsive performance. This is all the more impressive when you consider its relatively low price. They are not a simple plug and play replacement though and we needed to construct a new mounting system under the grille to get a perfect fit, of course, this is no problem for us.

As good as the Audison APX4 speaker is it is only a 4 inch and cannot be expected to deliver the bass requirement for a convertible car. We have had a lot of experience with convertibles and one of our solutions where space is tight is to custom fit a JL Audio 6w3 into the passenger footwell. This magnificent speaker is capable of delivering more than enough bass from a very small enclosure.

The trick is to very carefully control the frequencies it plays to achieve a seamless blend with the mids. As we construct our own enclosures we can design each one to perfectly fit the car we are working on. For this one, we even wrapped it in genuine Porsche carpet to ensure a true factory look.

Very little space is taken up meaning there is no significant constriction of the passenger foot space. The enclosure is secured to the car using invisible fittings which means it can be removed without leaving any marks in the carpet or trim. Once the floor mat is cut to shape and trimmed it will look as if the sub had always been there.

Pioneer AVIC F88DAB:

One of the great features of the Pioneer AVIC F88DAB is its powerful equalisation controls. This luckily features two EQ pre-sets. This allows me to tune two EQ curves; one for roof closed and one for roof open ensuring the best sound regardless of the vehicle’s configuration.

I really enjoyed this installation;

it was relatively simple but really delivered above expectations. The sound was full and rich with as much bass as could be needed. The new head unit was feature rich and the owner fell in love with Apple Car Play instantly. The dash-mounted Stormtrooper is really going to enjoy the miles now!

Bose SoundTouch – Bringing Music Everywhere

It is true to say that music has never been more accessible. Anything you might want to listen to is only a click away. You can choose to purchase it via a download site but more and more of us choose to subscribe to a streaming service such as Spotify, Deezer or Apple Music.  For a small monthly fee the whole world of music is at our fingertips like a vast lending library and as a true on demand service, we no longer need huge collections of CDs cluttering up the place.

All well and good you say but what are we supposed to play all this music on; our phone’s headphones, computer or tablet?

That’s not going to sound very good, is it?

No, we want a high-quality hi-fi system and that surely is why we need our CD players? Well maybe, but there is a fantastic alternative from Bose; the SoundTouch system.

The Bose SoundTouch wireless music players are easy to use, sound amazing and look superb. They are feature packed and there is a solution for any situation where high-quality music is required.

So how does it work?

The Bose SoundTouch system is designed to connect to your home wi-fi network. This allows it to connect to any music libraries you may have on a computer as well as being able to connect to your broadband link to play internet radio from around the world. On top of this, the SoundTouch system is equipped with Bluetooth connectivity; so you can connect any portable device, phone or tablet and stream your music. If you do subscribe to a music streaming service such as Spotify you can play this directly from the Bose control app on your device. It doesn’t stop there either because this is a fully networked system you can wirelessly connect multiple devices; these can be independent in each room or grouped together to play the same music throughout the house.

The simple control app can be downloaded to as many devices as you want which means you should always have a controller nearby but just to add another level of simplicity all the stand alone SoundTouch players have volume, source and radio pre-set buttons on the top to allow quick operation.

Let’s look at the SoundTouch family.

SoundTouch 10,20 and 30.

These compact and versatile units just need a mains power supply and your wi-fi network to play all your favourite music. The smallest unit, the Soundtouch 10 is ideally suited to smaller rooms such as the bedroom or study while the SoundTouch 20 and 30 are completely at home in larger spaces. The SoundTouch 30 with its integrated woofer produces a magnificent sound that will fill any space with rich, powerful music. All are available in black or white to suit any décor.

SoundTouch 300 and optional Acoustimass sub and surround speakers.

The SoundTouch 300 is a soundbar of course but unlike any other. Of course, as part of the SoundTouch family, it has all the convenience and power of the network but adds connectivity for your TV. It carries the proprietary Bose AdaptiQ system to learn the layout of your room and seating positions; ensuring you always get the best possible sound. Even on its own, this bar can generate a very impressive surround effect but if you add the optional sub and wireless surround speakers you will have a true 5.1 surround system that will delight. Again, very easy to use and even the remote control can be programmed to emulate any other meaning your Bose remote can control all your other devices such as Sky, Virgin, and TV.

SoundTouch Lifestyle 650 and 600.

If you want the absolute best for your TV and living room then look no further than the Bose Lifestyle 650. This powerful and elegant system with its virtually invisible speakers is beyond compare. The feature list is almost endless but what really matters is the sound. This surround system offers a level of audio immersion that is simply incredible. From the deepest rumbles to the lightest detail this system plays it all with precision. Since it also contains the full Soundtouch system for your music the Lifestyle 650 and 600 are truly total entertainment systems.

SoundTouch SA5 amplifier.

You may have a great pair of speakers already or may want ceiling speakers to keep it neat. You may want speakers outside or in other wet places where it would be impossible to take a mains powered device. In these cases the Bose SoundTouch SA5 amplifier is perfect. This can be installed inside the house and speaker wires run to wherever they are needed. Full control is via the control app and there is an AUX input for connection of external devices (e.g. TV).

SoundTouch wireless link.

This unassuming little unit is brilliant. It has all the power of the SoundTouch network and Bluetooth connectivity. That means you can stream your music, access internet radio or Bluetooth link your mobile device. This can then be connected to any hi-fi unit, Bose or otherwise; giving you the full range of SoundTouch features on any entertainment system with an external input.

If you would like to learn more about the amazing Bose SoundTouch system and how it would work for you please feel free to call us on 01625 432707. Better still why not call into our shop on Sunderland Street in Macclesfield; where we can treat you to a demonstration and you can take advantage of our special in store deals.

 

 

Range Rover Recovery

The Range Rover Vogue or L322 as it’s known. A British classic with world beating all terrain capability that will take you anywhere in leather trimmed luxury.

Now anyone who has owned one of these will know that there are a few niggles with this vehicle and one of the common problems is the audio. One day the stereo will not make a sound or the screen will just show the Land Rover logo while the red light just flashes on the volume control. This usually means the main amplifier has failed in the rear of the car. It could also be a failure of one of the other components in the audio chain but the amplifier is most common.

The cost of a replacement from Land Rover will leave you shocked, an eBay one will set you back a few hundred pounds with no guarantee and you may be no further forward if that is not the problem. Even if it is you will only have the same performance as before. Wouldn’t it be nice to properly improve the system while you have the chance?

This was the situation our customer recently had and after a short discussion and a budget decided upon we set to work overhauling the whole system.

The vehicle owner had specified the Pioneer Avic F88DAB head unit.

The rest was up to us.

The first job was to strip out all the unnecessary kit in the rear of the vehicle and from the dash.

Not for the feint hearted but reasonably straight forward when you know where all the hidden screws are! We will, of course, be rewiring the system so there will inevitably be many unused plugs on the original looms. These cannot be left to rattle around the back of the dash so we make sure that each unused end is padded and secured. There is also a reasonable amount of modification required behind the dash to allow the double din unit to fit. We have done quite a few of these and are used to it but again great care is needed.

Once the car was stripped it was time to install the new cabling. We had already decided on the system components and so we produced a custom loom for this. The Range Rover is a big vehicle and it still surprises me how long these looms need to be. All the service accessories need to be installed for the head unit; such as the Bluetooth microphone, dual USB ports, DAB and GPS aerials. We usually fit one USB to the centre arm rest bin and one to the glove box while the other items are discreetly fitted for optimum performance. I also replaced the original rear view camera that had failed. Car & Home Stereo can install a new camera into the original housing keeping the OE look.

Now the head unit can be installed and the dash rebuilt.

I think you will agree that this now looks far better!

The next task was to upgrade all the speakers and we decided on Audison all round. These Italian speakers are superb and so much better than the fitted Harmon Kardon units. A component set was installed in each door.

Now for the fun part!

Knowing the tastes of the customer we knew that he would want plenty of power. Space is a little limited so we needed an amplifier with high performance but compact size and the perfect candidate was the fabulous JL Audio RD 400/4.

This compact power house is a gem of an amplifier boasting 100W per channel. The sound quality from these is amazing. It shares a lot of the design features of the award winning JL Audio XD amplifiers but at a lower price.

This amplifier will fit perfectly in the metal rack assembly in the boot cavity. It is hidden but easily available for any adjustments required.

The results are astonishing. The improvement over the factory system is huge; the detail at the front is crisp and the bass performance feels solid with no distortion. I would recommend this system to anyone with a failing factory audio.

If you would like to know more about how we can improve the system in your Range Rover (or any vehicle) please give me a call; on 01625 432707 or better still call into the shop on Sunderland Street in Macclesfield.

blue audi s3 car and home stereo macclesfield

Awesome Audi

We have recently completed the audio system for this magnificent Audi S3. If you have read the previous instalment you will already be familiar with the car but it has developed considerably since then! This piece is a perfect example of how we work with our customers to achieve their audio dreams.

This has been a developing project in the quest for the best performance. What started as a simple bass upgrade has turned into a monster!

First things first:

When the car left the factory it was equipped with the B&O audio system and was quite frankly appalling. The front end detail was reasonable but the bass response was dire. The ‘sub’ that was fitted in the boot was a flimsy plastic chamber with a low quality, 6-inch paper and plastic speaker. Any attempt to push the bass resulted in a feeble burp, it had to go.

During the discussion with the owner it quickly became apparent that he was a true music addict and a simple upgrade was not going to be on the cards, he also admitted to being a JL Audio fan which we definitely approve of. We applied the simple motto that you can never have too much, only too little and recommended a JL Audio 12w6 subwoofer and an XD 1000/1 amplifier to drive it. Now we already knew that the signal from the factory amplifier was poor so we also recommended a JL Audio FiX processor to clean the response up.

The 12w6 sub is one of my all-time favourites and the results were very impressive but it wasn’t long before the bug bit again and our customer returned for more. Another 12w6 and XD1000/1 later the bass performance was doubled. Brilliant, but now the front end was starting to sound really bad in comparison, so a speaker upgrade was discussed.

Copious amounts of Dynamat inside and out kept the noise and vibration down while a set of JL Audio C5 650 components went in the front. This was all powered by a JL XD 400/4 in active mode while the awesome TwK processor allowed me to carefully tune the system.

 

The sound was amazing and that could have been where it ended, or so we thought.

Next Steps:

The owner of the car felt that there was a slight gap in the low mid frequency performance, and knew that there was room for an extra speaker in the middle of the door. That speaker can only be a 4-inch shallow unit so we knew it could not add the desired low mid. However the main door speaker location can accommodate an 8-inch driver and it just so happens that JL Audio produces a fantastic eight inch, free air mid bass unit, the ZR 800 CW.

This is a big driver but with a carefully designed spacer collar, it just fitted into the lower speaker position.

So what should we use for the high-mid and tweeter? Unfortunately JL Audio does not currently have a slim 4-inch but there is one company that has the perfect solution. The Focal 100KRS is a magnificent small speaker we use it a lot in Land Rover Defenders and know its potential so this was what we recommended. Again we produced mounting collars and the fit was perfect.

Of course, this extra speaker needed driving and there was really only one option for us and that was the JL Audio XD 800/8.

This allowed us to drive the tweeters and 4-inch mids at 100W while delivering a full 200W into each ZR mid-bass driver. Another cool feature is that the 800/8 shares the same chassis with the 1000/1 so now we had three identical looking amps in the boot!

What a sound we had now. The low mid gap was gone and the punch was quite something to experience. Thanks to the TwK processor the sound stage was crystal clear and right in front of the driver.

Was this finally the end? Oh no!

One thing still had to be addressed, the boot build. “Oh and while you do that since we can’t get a third sub in the boot can we squeeze any more performance from the existing two?” Challenge duly set we opted to refit the subs into slot ported enclosures giving us a realistic increase of up to 9dB from the same amplifiers. The owner wanted blue Alcantara to match the car with a raised JL motif on the box. Well, how could we refuse!

There’s definitely no room for golf clubs but that hardly matters when you hear this. There is, of course, a bass control at the front of the car and when wound up to full this system leaves you breathless.

This install has turned into one of my favourites and complements this gorgeous car perfectly. Look out for it at a show near you and you might just get to hear it.

Factory ‘upgrade’ systems

Recently I have been working on two cars that had factory upgrade audio options fitted. A Nissan GTR with the Bose system and an Aston Martin with the Linn option. My customers were both complaining of poor sound and were wondering how it could sound so bad when the car had the upgraded audio. Now both Bose and Linn are respected hi fi manufacturers who produce excellent products, at Car and Home Stereo we sell the full range of Bose home audio and have supplied Linn audio in the past. I know it well and have a lot of respect for them.

Clearly, both these manufacturers know how to make great audio so what goes wrong when they try to create a car audio system? And I’m not singling out these two, the Harmon Kardon, B&O, Meridian and Mark Levinson are little if any better especially when you consider the cost of ticking that upgrade option box. In my opinion, the short answer is money and marketing while the longer answer is a fundamental misunderstanding of the car environment.

Xcar:

Let’s take a fictitious, generic car manufacturer, Xcar. Let’s assume they are successful and respected producing a high-quality product with flashy showrooms and huge marketing budgets. They need to keep their cars selling and beating their competitors. This competition is excellent for the consumer as it forces the car manufacturers to constantly improve their vehicles. More power, more fuel economy, more safety, more features. More is always better, isn’t it? Of course, at the same time, they need to balance this innovation with costs so that they can turn a profit.

Now Xcar have a mid-priced car that sells very well but is in close competition with its rivals. How to make it more attractive while making more money? This is where the option list comes into play and right up there near the top will be the audio upgrade.

Remember that to marketing people more is always better so obviously, more speakers have to be better right? Wrong! At Car and Home Stereo we design audio systems with one goal; to sound great. What we use to achieve this is almost not relevant, there will be speakers, amplifiers and sound processors but the type and quantity will be decided by the customer’s requirements and personal preferences.

Some of the best sounding audio systems I have ever designed have used only four speakers and a subwoofer. The four speakers would typically be a two way component set comprising a mid and tweeter in each door so could be considered a single pair. A multitude of speakers means that there will be a lot of competing pressure waves in the cabin not to mention multiple reflections causing phase cancellations and ruining the sound stage. Manufacturers often put yet another speaker in the middle of the dashboard, perfect if it is to watch DVDs in 5.1 surround but terrible for stereo delivery.

But Xcar listens to the marketing department and offer a speaker upgrade package that takes the speaker count from six to fifteen. Of course, this many speakers are going to need an amplifier. They could go to a company that designs and builds car audio amplifiers for this but most people have never heard of Audison or JL Audio or Rainbow and Pioneer and Alpine are not considered up market enough. Marketing do their research and find that most of their customers have a house with some decent hi fi so why not get these hi-fi companies to build them an amplifier?

There are two major problems here.

The first is that the car manufacturer has gone to a home audio company. There are fundamental differences between your car and your living room, too many to mention here and most home audio companies simply do not understand them. At Car and Home Stereo we of course use amplifiers from the best car audio manufacturers and while these can be expensive they are ideally suited to the vehicle environment to ensure the best possible sound.

However, the biggest problem can be laid at the feet of the accountants. Remember they need to make more profit without increasing costs too much well putting a big brand hi fi badge on your speaker grille and installing the lowest cost amplifier can do that. The badge might even convince customers that this is great car audio.

amplifier upgrade Nissan GTR Skyline

This is the upgrade amplifier option for the Nissan GTR Skyline. Designed to drive seven speakers even the simplest offering from Hertz would outperform it. And there is the problem, Bose are completely capable of designing and building a tremendous amplifier but car manufacturers will not pay the price for this and go with the least expensive option. That doesn’t stop them from charging a hefty premium when you tick the upgrade box though.

You might assume that you are getting better speakers designed by that hi-fi manufacturer wouldn’t you?
Well more often than not you actually only get the standard speakers with a few more thrown in.

So what have we learned?

My advice is to never tick the upgrade audio box. You will most likely be disappointed and when it comes here to be improved I will usually have to remove it all anyway. Any changes I make will be completely reversible and invisible to any inspection but the difference to your listening experience will be astonishing. You will start to relish the long drive and hold ups will be almost a pleasure as you will have your favourite music in stunning clarity to keep you company.

If you would like to know more about how we can improve your car audio or would like to listen to our stunning Land Rover Discovery demonstration vehicle please feel free to pop into the shop on Sunderland Street in Macclesfield, Cheshire or give me a call on 01625 432707

Hertz Speakers

If you know our installer Tim at Car and Home Stereo you will know he is passionate about sound. His love of music extends beyond the shop into regular playing with his band and it is this passion that is reflected in everything we do as we strive to get the best possible sound for you. We are constantly looking for and testing the latest equipment available to help achieve that result.

We stock high-end equipment from JL Audio, MTX, Audison, Rainbow, Eton and many others but today I would like to highlight one of my favourites, Hertz Car Audio.

Hertz car audio is part of the Italian Elettromedia group, a company dedicated to producing the best possible audio systems. From the outset the Hertz brand has stood for excellent quality at an affordable price. Their bright orange packaging has become synonymous with performance and value for money. It is no coincidence that we chose Hertz speakers and subwoofers for our Land Rover Discovery demonstrator. The Hertz Mille Legend components fitted in the front doors never fail to impress.

Speakers:

The Hertz car audio speaker range has something for everyone. Sometimes we just need to replace a failing set of factory fitted speakers or provide an inexpensive upgrade to improve the sound. The perfect solution here is the Hertz Deici range. There is a perfect fit speaker for any car in this series and with prices starting at only £59.99 per pair they won’t break the bank. In reality, these sound really good and outperform anything else I can think of at this price point. As well as the speakers there are subs and ready-made enclosures in the Deici range and they all perform brilliantly.

Hertz DBA 200.3 self contained speaker uni

For example, the Hertz DBA 200.3 is a self-contained twin 8-inch sub with a 140W amplifier. The compact size means it will fit in any car boot and it is designed to work with any car radio head unit meaning adding bass is simple.

If you were looking for more performance I would immediately recommend the Mille Pro range. These speakers have it all; precision, power and loads of energy. The 6.5 inch mid and tweeter sets start at under £300 and represent amazing value for money.

mille pro 6.5 inch mid and tweeter

As you can see the build quality is astonishing. The main driver boasts a large over rolled hinge to allow an extended excursion; this means much punchier bass performance while the relatively large tweeter has a respectfully low Fs allowing a seamless blend with the mid. In fact, this tweeter shares a lot of technology with the higher spec. Legend tweeter which is incredible at this price.

Legendary:

But of course, if you want the best then that means installing the Mille Legend 1650.3.

This is what I listen to every day and every day they amaze me with new detail. I love this tweeter and in fact the whole set up is seamless with a truly accurate frequency response over the entire audio spectrum. With a good amplifier essential to extract the best from these speakers you will be rewarded with a smooth enveloping sound that is easy to listen to with no fatigue.

Of course, there are matching subwoofers and all I can say is please come down to the shop on Sunderland Street in Macclesfield to audition the 8 inch Mille sub in our Discovery, you will not believe it is so small when you hear it!

As if the above were not enough Hertz have other speaker lines to fill specific niches. There will be a full range of marine grade speakers soon which to be fair we will probably not stock, Car and Home Stereo not being near the sea! However, a range we do supply is the awesome SPL Show range, specifically designed for the competition scene these are a no compromise power product where loud is everything.

So as you can see there is something for everyone within the Hertz car audio speaker range and if you are thinking of an upgrade then please call us so that we can match the right system to you.

Special Offer.

In fact, we have put together a superb package for a limited time which would grace any car.

car and home stereo special offer soundsystem

The system comprises the fabulous Hertz MPK 165P.3 component speakers, the brand new Hertz DPower 4 amplifier and the Audison ultra compact APBX 8R sub enclosure. Normally this system would be £810 but we have a limited number of kits for only £600! An amazing saving for such a high-end system and of course we can fit it for you if you wish. Don’t forget that all this comes with a three-year warranty if we install it.

We hope to hear from you soon.

Campervans: Upgrades and Audio Systems

Day vans, campervans, motorhomes; whatever you call them, they have never been so popular. Two of the most familiar conversions are the Fiat Ducato / Peugeot Boxer / Citroen Relay and the evergreen VW Transporter. Whatever you drive, at Car and Home Stereo we have a vast range of products to improve your enjoyment when out and about.

Keeping it quiet:

If we can get to the vehicle before it is converted we recommend a comprehensive sound deadening treatment. This involves using a combination of Dynamat Xtreme and Dynaliner foam sheet to remove vibration, dramatically reduce road noise and to thermally insulate the vehicle.

dynamat car sound system

Dynamat is a thin and light sheet that is applied to the metal panels and prevents any vibration from being transmitted. This means an enormous reduction in road noise. It is applied to floor, sides, doors, and roof for optimum effect.  Dynaliner sheets are then applied over the Dynamat in varying thicknesses to create a thermal and acoustic barrier.

This insulation retains heat and again reduces external noise even further. When done properly the van will be significantly quieter and warmer. If the van has already been converted then it is still advisable to treat any panels that can be accessed as any amount will be beneficial. The Dynamat advantage is that as the patented market leader it is lighter and more efficient than any other product meaning you can use less.

Finding your way:

The joys of the open road are many and the ability to just start up and go are what make camper vans so appealing but really knowing where you are going and how to get there can definitely reduce the stress. Of course, I’m talking about navigation and we have a wide range of solutions available to be fitted. One of my favourites is made by Pioneer; whilst there are many great units out there I think the Pioneer AVIC F980DAB-C camper version is one of the best.

The feature list for this unit is extremely impressive as it boasts CD, DVD, FM/AM/DAB tuner, Bluetooth, Apple Car Play, dual USB, reverse camera input and of course class leading satellite navigation. All this performance, however, is not complex to use and that is one of the main reasons for its success. Pioneer have put a lot of effort into keeping the user interface simple meaning you can keep your eyes on the road, navigation instructions are clear and given in plenty of time for a safer drive. As this is the camper version the software is specifically designed for larger vehicles to ensure a safe route is calculated. It also contains a massive ten million points of interest database for the whole of the European continent to make sure you are completely informed.

Alpine:

Another fantastic unit is by Alpine and offers a massive 8-inch touchscreen. This unit is custom designed for the VW T5 / T6 and is quite simply stunning.

With a feature list as long as your arm this unit is unbeatable and as it has been designed from the ground up for the VW it blends seamlessly with all the vehicle systems.

To get the best out of these sophisticated systems it is imperative that they are correctly fitted. At Car and Home Stereo we have been installing audio systems in Cheshire for over 40 years and in fact were one of the first to install navigation in the UK. We have vast experience with these products and of course have all the ancillary parts to ensure a seamless fit in your dashboard.

Reverse with confidence:

One of the downsides of a camper or in fact any larger vehicle is the rear view. It can range from difficult to impossible to see backwards. Many newer vehicles are fitted with reverse sensors and that is certainly something we can fit your camper but there is no substitute to actually seeing what is there. We would always recommend a reverse camera. If you do not have a screen already we can install one discreetly and reversing will no longer be a chore. If you use the vehicle to tow then the camera can be angled to view the tow bar; making hitching up so much easier.

Using a combination of mirrors, camera and sensors reversing into the tightest of spots will be a breeze.

Sounds fantastic:

Your camper is a true “home from home” but as they are often based on commercial vans, unfortunately, the audio performance can leave a lot to be desired. As one of the leading audio installers in the UK, we are ideally placed to make this better for you. In fact, this is an area where we excel as our experience with leisure vehicles is extremely broad.

If you already have an upgraded head unit or are happy with the one you have then we would recommend a speaker upgrade for the front doors and while we’re at it why not add some speakers to the rear of the vehicle? One of our favourites is by Italian manufacturer Audison. The Voce K6 is a component set for the doors or dash and offers a true HiFi performance when correctly installed.

We also have custom designed subwoofer enclosures that can be completely hidden meaning you can have a full sound without losing any useful space.  We often use the JL Audio 6w3 subwoofer as its compact size and stunning performance make it ideal when space is at a premium.

Life In The Loud Lane

At Car and Home Stereo we are dedicated to getting the best possible sound in your car. We will carefully match your needs to the best equipment and electronics to achieve that goal. We have access to a vast range of products so that we can tailor a system that is perfectly suited to you and your car. Of course what everyone wants is different and two extremes were both in the workshop at the same time recently.

If you have read the Lotus Evora blog you will know that the emphasis was on a stealthy install with the aim to produce a highly detailed soundstage. This was achieved with a full Audison system using the amazing AP8.9 Bit amplifier, Voce speakers and Prima sub, a simple system boasting 520W, more than enough power for the small cabin of the Evora. The final tuned sound of this car was fantastic. The music was surrounding with detail and punch where it needed it.

In the adjacent workshop bay at the same time was a Vauxhall Astra van and the brief for this one was very different. This had to sound good but most importantly it needed the ability to crush you with bass! Being a van we had plenty of space to work with but on the down side all that metal was a prime candidate for epic vibration. Power supply was always going to be an issue from the standard battery and of course with the power we were going to need, the standard wiring would not be adequate.

How we did it:

The first job would be to strip the vehicle for acoustic treatment. Every panel had to be coated to make sure all the enormous energy of the subs was retained inside. There’s no point in installing a 3000W system if 1000W gets out, it might sound good to passers-by but if you’ve paid for all that power, you want to hear it all. Once treated, tapping on any metal panel sounded like tapping on wood. There was no resonance and as a bonus road noise was reduced to almost nothing. The doors were treated with more Dynamat Xtreme to improve the acoustic response of the front speakers and again reduce road noise.

What next?:

The power supply was upgraded with two auxiliary Optima yellow top, deep cycle batteries with a split charge system. Even though the MTX bass amps are ‘D’ class they still draw a significant current and it was important to make sure this would not drain the vehicle battery. This kind of power has to be made safe and that means fuses on each battery and on each supply to the amplifiers, there may only be 12 Volts but the current capacity on the Optima batteries is more than enough to melt any cable and incorrect fusing could cause a fire if short circuited.

Once the power supply was installed we could mount the amps on the forward bulkhead. As this was destined for the show scene we made sure that everything was as neat as could be.

The eagle eyed of you will spot the cut outs for the MTX 6×9 speakers below the amps. This is an unconventional position for speakers as they are behind the seats but they will add a much needed boost to the low mid-range to complement the component speakers in the doors.

The three main amps are MTX RT1000.1Ds, These develop 1000W each at 2 Ohms which is why they need 50mm sq. power cable! The rest of the speakers are powered by a JL Audio XD400/4 and everything is kept under control by the Audison Bit 10. The front speakers were mounted in the standard location on custom collars and the tweeters were mounted into custom ‘A’ pillar pods.

This improved the staging for the front and solved the problem of the size of the tweeter being too large for the factory location.

So what about the subs I hear you cry!

Well this had to be the show stopper so we knew we would have to build something a bit special. The MTX TX612 is a beast of a sub.

With its awesome power handling capability we knew we could really push this speaker. It has incredible excursion and that red, double stitched hinge is not just for show. We wanted to get the most from this driver so we opted for an optimised slot ported enclosure, one for each sub. As you can imagine there is a significant amount of weight here so we also had to make sure that there was no possibility that any of this structure could move. Safety is always prominent in our minds when designing any system.

This is the finished enclosure although there will be trimmed wheel arch boxes either side for storage.

The auxiliary batteries and fuses are located behind the enclosure and are accessible by removing the top trim panel. There will be a voltage display mounted in the right hand arch box so battery condition can be monitored. The main fuse and Stinger 500A peak split charge relay are mounted in the bonnet with the vehicle battery.

Did we fulfil our brief?

And then some! With the tailgate open the bass completely dominates and you can feel the sound waves pushing your chest. If you dare to put your head inside the boot you’re immediately disorientated by the sound pressure level. When sat in the front you can hear the rest of the music as well and now that awesome bass complements rather than overpowers. Of course there is a level control for the bass but the temptation is to turn it up for the biggest smiles!

At Car and Home Stereo we know that this sort of system is not for everyone and we always ensure you get exactly what you need so regardless of what vehicle please give us a call and we can start your journey to a better sound.

 

Exotic Evora


The Lotus Evora 400 is a true super car. A fire breathing 3.5litre V6 will propel this rocket to 60 in under 4 seconds and on to a top speed of over 180 mph. But, when you have finished playing with the race controls, stopped grinning at the insane acceleration and started to use the car every day you will probably start to notice something. The audio system is quite frankly awful. The infotainment head unit is an Alpine 990 navigation multi media player and as such is really quite a performer but after that it’s not so good.

There are a pair of Clarion 5 inch speakers in the doors and a pair of unbranded tweeters on the ‘A’ pillars. There is even an 8 inch sub powered by a small Alpine amp just behind the driver seat but you’d hardly know it. Of course the audio system was low on the priority list when designing this car but the sound quality for a £70K+ car is not good at all.

So what should we do to improve it?

We don’t want to add a lot of weight and I think it’s important to keep it discreet. There is no real need to change the Alpine head unit unless more features are required but everything else will go. The car’s owner agreed and was most interested in a high quality sound at all levels. He did not need it to be extremely loud but of course it has to be able to compete with the exhaust! From our previous experience with the Lotus Evora we know that the low mid-range gets lost in the road noise so we need to fit a speaker that can cope with this and also EQ the car appropriately.

We opted for the super flexible Audison Prima AP8.9 Bit amplifier as the heart of the system.


This is an 8 channel, multi input amplifier with a full digital signal processor on board. This allows me to configure the amplifier outputs as required and then to tune the system to the exact requirements of the installation. It is also very compact for the output and will fit neatly in place of the Alpine sub amp.

The speaker set would be the wonderful Audison Voce K5. I would not use the passive crossovers as I can set all the frequency slopes and cut offs in the amplifier.

The choice for the sub was easy, the Audison APS8R.

This slim 8 inch sub is perfect for the existing enclosure once it has been acoustically treated with sound deadening.

The first job after carefully stripping the vehicle interior are the tweeters. I must confess that I have done this on a few times now and know they are a great fit. A very slight modification is required to the ‘A’ pillar but the original tweeters could still be replaced if required.

 I absolutely love this tweeter. It is smooth and very detailed without any harsh edges at the very high end. It is quite large but that allows it to be blended seamlessly with the mid-range.

 

The door speakers in the Lotus are in a good location high up at the front of the door but they are mounted in flimsy plastic collars. The K5 mid driver is somewhat deeper than the Clarion unit so a set of wooden spacers are made to increase the depth available.

                             
Naturally we apply sound deadening to the door both inside and out to improve the acoustic properties of the space. Since we will run this as a fully active system from the amplifier we have to rewire the speakers, tweeters and sub. This is a significant amount of cable and in such a compact car can be a challenge to lay but of course we are will ensure nothing can be seen.

Moving to the back we mount the amp in place of the Alpine unit. The first job is to construct an amplifier plate and trust me when I say that even with the compact AP8.9 Bit that space is tight!

A new power supply is taken to the boot mounted battery and everything is loomed and tied down tight to make sure nothing can move. Once the amp is in place we apply appropriate sound deadening to the area where the sub will mount and when the panel goes back into place there is absolutely nothing to show that any changes have been made (although if you look closely you can just see the Audison logo through the grille).

With everything built back up we can turn our attention to tuning the system. Of course we can only partially tune any new system as the speakers need time to run in so we will definitely want the car back in a week or so. However we can set up the time correction, phasing and crossover frequencies at this point.

As I mentioned the Audison AP8.9 Bit is an 8 channel amplifier so with 5 speakers it is configured as a 5 channel with a bridged output to the sub and mids ensuring full power is delivered where it is needed and because it has multi input capability the Alpine sub level control continues to operate.

With the time correction, initial EQ and phase adjustments done the sound stage is right in front of the driver and appears to come from just above the dashboard! There is now a sparkle and liveliness to the sound with a beautifully blended sub and mid response. Playing Michael Jackson’s Thriller is a great test and this does not disappoint, the sound is crisp and punchy with really wide stereo separation, the footsteps at the start seem to walk right across the dash and the door slam is epic. The bass is smooth and can be adjusted from off to ‘back massage’. Time will tell if the mid-range needs to come up more to compensate for the driving noise but right now with the engine running the music sounds spectacular.
