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!

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.

stripped dashboard range rover car and home stereo macclesfield

stripped range rover dashboard macclesfield car home stereo

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.

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.

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

campervan interior sound system car and home stereo macclesfield

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.

sat nav pioneer car and home stereo macclesfield

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.

alpine unit 8 inch touch screen campervan T5 T6 car and home stereo macclesfield

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.

reverse camera vehicle campervan tow bar car and home stereo macclesfield

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.

Here’s one we built into the rear of a Land Rover Defender showing how small the speaker box can be while still producing a tremendous bass performance.

Don’t wait:

With summer almost upon us, it’s definitely time to get these jobs done. Whether you want a complete upgrade to your leisure vehicle audio or maybe just want a bit better sound we can help. We are the car audio experts in Cheshire and are here to help. If you are local to Macclesfield please call into our shop on Sunderland Street or simply give us a call on 01625 432707 our advice is free. If you do choose to upgrade we can offer up to a three-year warranty on products as well as a lifetime warranty on all installation for peace of mind, heck we’ll even throw in a cup of coffee!

 

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’.

Audio Installation with Full Instrumentation!

Over the 40 years that Car and Home Stereo has been installing audio systems to cars we have seen enormous changes. Changes to the source units available (who else remembers 8 track cartridges?!), changes to the playback systems and of course changes to the vehicles themselves. While a 1970’s Ford Escort shares a common purpose with a 2016 Audi TT, they share very little under the skin.

Most vehicle systems now are completely controlled by the on-board computers, true Drive by Wire. These systems have meant much greater reliability, higher efficiency and flexibility. However it has also led to a much lower tolerance of interference with respect to changes. Even the slightest change to a vehicle system can generate fault codes and even lead to vehicle malfunction.

This, coupled with fully integrated entertainment systems would appear to spell the end of audio upgrades, leaving you stuck with the dull factory installed system but help is at hand!

Fortunately our industry has risen to the challenge and developed systems that can be seamlessly integrated with any factory system regardless of complexity.

If you have a Bose or Infinity audio system in your car then the speakers may well be of a lower impedance than standard. This would mean a blown speaker could not be replaced with an alternative to the factory part but we now have speakers that are specifically designed to be added to factory systems meaning perfect fit and far better sound.

You may want to change the basic radio in your VW Golf to something with DAB radio or satellite navigation. The standard VW radio also displays parking information and climate control settings, there are controls on the steering wheel for volume and track search. These are features you would not want to lose and we can supply units that have all the facilities you may want as well as supporting all the standard vehicle displays.

With the advent of computer controlled systems there are also hazards to changing the head unit to one that is not compatible with the vehicle wiring. The results can be from your new unit not working to damage to the electrical system. At Car and Home Stereo we take safety very seriously and have a wide range of specialist interfaces to ensure that any new system integrates perfectly with your car.

Pitch Perfect – Rainbow’s Profi Line

Here at Car & Home Stereo Macclesfield, we’ve fallen head over heels for the Profi brand.

Uncompromisingly brilliant, these incredible pieces of equipment embody the precision and passion of real expert craftsmanship. The sound is so crystal clear, that you feel as though you’re at a live performance. Our resident car audio system expert and musician Tim described the sound as ‘utterly transparent’, and when you hear what these speakers can do when installed with precision – you understand why.

We’ll be honest, Profi line is not the cheapest way to get your hands on an audio system for your car. However if you want the best possible quality of sound, we think the Profi kit is worth every single penny. In common with all high end car sound systems, proper installation is vital to getting the quality of sound that you’ve paid for. Here at Car & Home Stereo of Macclesfield, we have a trained musician and qualified sound engineer with a passion for crafting perfect audio environments. Tim Campling offers a bespoke and comprehensive instillation service, tailoring each of his creations to the requirements of your vehicle and sound system – achieving perfect harmony between the two.
