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.

At Car and Home Stereo we are experts at creating wonderful sound for your car.

Time for a New Lifestyle

The amazing Bose Lifestyle 650

Car and Home Stereo have been supplying exceptional Bose music and home theatre systems for over 20 years. I still remember the first time the original Acoustimass speaker cubes were demonstrated to me. Tiny speakers that twisted with a sound that seemed to fill the room, very impressive.

From that day we have stayed with Bose as the ‘Home’ in Car and Home Stereo. Some of the most exciting products have been the Lifestyle range of home cinema systems and over the years we have seen continuous and dramatic advances in technology and performance.

The core design feature of the Lifestyle systems has always been amazing, immersive sound from almost invisible speakers. The latest version, the Sound Touch Lifestyle 650 takes this to another level. Let’s take a tour of the technology and features of this incredible home cinema system.

 

The speaker system is revolutionary. The diminutive OmniJewel speaker houses two drivers positioned at the top and bottom with the sound radiating from the central grille.

 

This allows for complete 360-degree dispersal and creates a huge image stage all around the speaker. If the speaker is wall mounted then the reflected sound adds to the widened soundstage. The result when all five speakers are connected is a truly immersive sound with exceptional image separation, perfect for movies. To make installation easier the rear speakers have a wireless connection to the control unit meaning no more wires to chase around the room.

Of course no cinema system is complete without the woofer. This is what creates the power and excitement in the soundtrack.

 

 

The Acoustimass 300 bass unit

From the cutaway, you can see how the driver is positioned under the sleek glass top for maximum dispersion without rattling the floorboards. The tuned port below the speaker enhances the truly deep tones perfect for when the star destroyer thunders across the sky! Again the woofer connection is wireless meaning it can be positioned anywhere and just needs a power point.

But what if your room is an odd shape making it difficult to install the speakers in the ideal positions? Maybe you have high ceilings and wood floors which can produce odd reflections and ruin the sound. Well, Bose has the answer in their AdaptIQ system. This learns the layout of your room and listening positions and automatically adjusts the sound to compensate for anomalies. This means that every system will sound as good as the showroom and you will not need to carefully position your speakers to optimise performance.

Finally, we come to the gorgeous console.

The sleek Sound Touch 650 console

Available in black or white this sleek, glass topped unit is the brain of the whole system and packs an amazing suite of features and technology. It is designed to be the hub of your entire audiovisual system. There are multiple HDMI ports to accept all your devices such as Sky, Virgin, Blu-Ray player and others. There is a single ARC equipped HDMI port for connection to your television but if your TV does not have ARC then there is a dedicated optical port for the TV sound. The smart Bose remote control can be programmed to operate all your other devices which means a lot less clutter on the coffee table!

That takes care of all your video needs but what about your music? Well, the Lifestyle 650 is equipped with Bluetooth for direct streaming of music from your phone or tablet but more importantly, it has the Bose Sound Touch wireless music system on board. This simple system links the Lifestyle to your wifi network and any connected devices. This means it can see your iTunes or My Music library on your computer or network drive giving you instant access to all your music. If you have a Spotify or Deezer account you can access that from the Bose control app on your smart device and play it through the Lifestyle system. There is also internet radio access giving you just about every radio station in the world in digital clarity.

All this technology is incredibly easy to control either via the Bose Sound Touch app or the system remote control which I think is important as we shouldn’t feel intimidated by an overly complex control system. You barely need to look at the instructions as it is so intuitive to use, the system even talks you through the installation making sure no mistakes are made during setup all thanks to the Unify installation process. System updates are automatic via your wifi connection meaning your system will always be up to date and upgraded as necessary.

And there is so much more to the Lifestyle system that makes it one of the best home cinema systems available today, far too much to talk about here. I would urge you to call in for a demonstration so that you can experience the full power of this magnificent range.

 

Simplicity Wins

At Car and Home Stereo we regularly install very high performance, in-car audio systems. It is intensely satisfying to build these systems as the musical performance they deliver is breathtaking. These systems do of course come with quite a high price tag so what can we do if the budget is a little more modest?

Let’s meet ‘James’. He’s 22 and just bought his first new car, a Ford Fiesta ST.

ford fiesta st

He loves music and thinks the standard sound system is OK especially since the car is equipped with Bluetooth so he can stream from his phone. After owning it for a while he starts to think about improving the sound but after lease payments and insurance he’s not got a lot to play with.

The first thing we will ask when he calls in to the shop is what type of music he listens to and what sort of sound he likes. The next step is to sit in his car and listen to the sound, often we will find the tone controls have been set to max bass and treble in an attempt to get a better sound. This usually just has the effect of making the sound muddy as the speakers cannot cope.

Now we know he would like a better bass performance for his music and more clarity from the main speakers. We need to add a subwoofer and better speakers to achieve a complete improvement. James has a limited budget and wants to get the best performance boost for the money.

We have a wide range of products available to suit all requirements but in this case an ideal solution would be the Rainbow Intellisub 8 and a set of JL Audio TR650 CSI components for the front doors. Total cost installed of £500. This very simple system would transform the performance of the audio and give years of pleasure.

But what if the budget will not stretch to £500, should we find cheaper products? The answer is always no. It is never worth compromising performance for price. There are cheaper products out there but they are always inferior and will not stand the test of time. The best option is to split the installation and have one part now and the next when funds allow. So which part first?

Simple, the sub. By adding the extra bass system there are two immediate benefits. First and most obvious is the bass improvement with greater depth and punch. The second improvement is more subtle, as there is no need for the main speakers to produce bass they start to sound a lot better. Certainly good enough while you save for the speakers!

I give this advice on an almost daily basis and it’s worth has been proved time and again with customers who have simple audio systems that far exceed their expectations. We have an in store demonstration stand that shows this off beautifully so please feel free to call into our shop on Sunderland Street in Macclesfield and we can start your journey to a better sound.

Wishing you a happy new year!

We hope your 2017 has got off to a good start!

Here, at Car and Home Stereo we already have some exciting, new products coming through the door. Come to our shop on Sunderland Street, Macclesfield, and see what we can do for you.

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.

Of course you may want a complete upgrade to your system but do not want to alter the look of your dashboard. This is an area in which we excel. Whichever car you drive with whatever audio system we can improve and add to it. Regardless of complexity we have the tools and skills to seamlessly upgrade your listening experience. With the products from Audison, Hertz, JL Audio, Pioneer, Alpine and many others we can create your perfect sound system.

We look forward to seeing you.

Selecting a Subwoofer : The Nitty Gritty

Most music consists of a full range of audible frequencies, from low bass (bass guitar, cello etc) to high treble (cymbals, piccolo) although a notable exception is John Cage’ Four minutes and Thirty Three seconds. In simple terms – the lower the sound, the longer the sound wave and the more energy required to generate it. In practical terms – bigger speakers and a more powerful amplifier.

IMG_0584

“Bass is an essential part of music and is the part that adds the drive and excitement, try to imagine Michael Jackson’s Billie Jean or Prodigy’s Fire Starter without any bass, for example.”

“Can’t we just use a more ‘bassy’ speaker?”

To explain why this is not really the answer we need think about what a speaker is doing. In its simplest form a speaker is a vibrating membrane that is generating sound (pressure) waves and to produce lower sounds, the speaker cone has to move more slowly and further. This is no problem on its own but at the same time we need it to produce the mid and treble frequencies. These sounds require a very quick response and result in a very complex vibration pattern. Expecting a speaker to do both low and high frequencies inevitably ends in a compromise of both. The practical result of this compromise is at best a muddled, less defined sound and at worst a distortion that will lead to the destruction of the speaker. The only solution is a dedicated bass speaker, a subwoofer.

_DSC0173

Fortunately there are a wide range of compact, high performance woofers on the market now. Speakers that will operate in very small enclosures and take up minimal space. In a lot of cases, where I’m upgrading a factory Bose or Meridian system, I can use the existing bass speaker location for a completely stealth installation. In many cases I can use wheel wells, under seat locations or custom build enclosures in boot recesses. Even when none of this is possible there are woofers from Jl Audio and Hertz that offer spectacular performance from a unit little bigger than a couple of shoe-boxes.

_DSC0182

At Car and Home Stereo my system designs are always sympathetic to the vehicle but most of all it is my passion for music and great sound that drives my recommendations.

Pitch Perfect – Rainbow’s Profi Line

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

_DSC0115

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.

 

_DSC0117

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.
