Sub-woofer: bass in not much space.

There is no getting away from the fact that every good car audio system needs a sub-woofer for a full range sound. By their very nature a sub-woofer needs to be large to play the frequencies required and it will also need to be in some kind of enclosure. So we have a large speaker in a fair size box, where is it going to go? Well that’s usually the boot. While the show car installations look great they can be a little impractical.

Just about room for a packed lunch in this one we made but on the plus side it did sound amazing.

What we often do is try to take up as little space as possible.

That could be by using one of the new breed of sub-woofers that are designed to operate in very small enclosures like the Audison Prima series.

These fabulous subs are completely at home in small boxes and are extremely slim as well. That means that even the 10 inch driver can virtually disappear into the boot leaving the lion’s share of the space free.

Sometimes however placing an enclosure in the boot is just not practical.

There might be a need for the whole of the load space, there might be wet items to carry such as bikes and prams or it might simply just look out of place. For those occasions we can build bespoke enclosures using existing voids so as to impose on the load space to the smallest degree.

That usually means fabricating with a composite of fibre glass and wood. We can mould these to be a perfect fit to the vehicle and when done right can sound amazing. The steps to producing one of these are always the same.

First we need to determine that there will be enough space.

All sub-woofers work best in a specific volume of air and it is essential that we do not restrict the performance by under sizing the box. Once we know that there is enough space we need to create a mould of the vehicle trim.

When I am happy that we have enough space the appropriate piece of vehicle trim is carefully removed and masked; before the first layers of fibre glass are applied. Once set this can be trimmed to the correct dimensions and the MDF front applied. Further layers of fibre glass are applied to seal the face to the enclosure. This can then be trimmed in an appropriate finish.

As can be seen, I like to line the inside of the enclosure with Dynamat sound deadening. This dramatically reduces any possibility of resonance and increases structural integrity.

By now the vehicle trim panels are all replaced and the enclosure can be securely mounted to the car. It is vital that the mounting is solid as although the enclosure is relatively light the subwoofer is not. This extra weight must be mounted in such a way that trim cannot rattle and of course the whole thing must be secure against movement during driving.

The final result is a discreet installation that uses a minimum of useful space.

I recently produced this enclosure for a Land Rover Freelander. As you can see it blends seamlessly with the vehicle and takes up no useful space. It contains the unbelievable Hertz ML2000.3 subwoofer. This 8 inch woofer has enough punch to fill the large Freelander with tight and deep bass and has a level of sensitivity that can play the lightest of bass notes.

Let’s talk about bass.

Music, like all sound, is made up of multiple frequencies. Think about a typical piece of music; there are high frequencies for cymbals and high voices; mid frequencies for most vocals, drums and guitar and then there are the low frequencies for bass drum, bass guitar, low organ or piano, synth and low register voice.

As you know almost all hi-fi speakers are made of several separate drivers; small tweeters for high frequencies, one or two dedicated mid-range drivers for the mid frequencies and a dedicated bass driver for low frequencies. There may even be a separate sub-woofer for very low frequencies. This separation of the speaker drivers is so that no one unit has to deliver too wide a frequency range which would lower the overall performance of that driver. This is most apparent if we try to get one speaker driver to deliver very low bass and mid frequencies at the same time, that is why we always see a dedicated bass driver or sub-woofer.


So if we want a true and accurate reproduction of music it is obvious that we need a sub-woofer. This is just as true for the car as well as the home and in some respects it is more important in the car as we have to allow for road noise and low frequency absorption of the interior.

The first thing I need to say is that a subwoofer is not just there to rattle the windows, it is an essential part of the audio system and has to have a true hi-fi performance to accurately reproduce the lower notes. I have often said that if you can hear where the subwoofer is then it is too loud. Its sound should blend with the rest of the music to create a complete sound stage that envelops the listener. These systems are often described as SQ or sound quality systems. The subwoofers do not need to be huge and do not need to dominate the boot, a lot of modern SQ subs are designed to work in small air spaces meaning I can build discreet enclosures taking up very little space.

In this car I constructed an enclosure that sat in a recess of the boot. We used the JL Audio 10TW3 as it is optimised for a small space but can still deliver a truly musical performance.

This car was a BMW Z4 with a custom enclosure behind the passenger seat using the JL Audio 6w3 driver.

Even when there are no hiding places to use we have subwoofers that are extremely discreet like the Audison Prima 8.

At only 4 inches deep this tremendous unit will not dominate the boot space but deliver excellent performance.


What if you do want that earth shaking, window rattling, feel it in your bones experience?
Often known as SPL (sound pressure level) performance; we are experts in delivering this as well.

Of course this does mean taking up space but usually that is never a problem! Here the emphasis is on power and lots of it.

These speakers need to be built to withstand epic amounts of power. They also have the ability to move huge amounts of air. That means they need a massive cone excursion capability and be strong enough to not flex under pressure.

Our new range of XFire subwoofers and amplifiers are built to deliver and then some! Designed by a European champion car audio competitor these subs are engineered to take anything you can throw at them. The 12 inch is rated to 4500W with an excursion (xmax) capability of 30mm one way (that’s 6cm front to back!). This monster can satisfy any requirement for ground shaking bass.

So whether you want sublime, discreet bass to complement the front speaker stage or the kind of low frequency you can really feel; we can design and install the perfect system for you.

Car audio upgrades, sometimes simple is best.

It is common when searching for ideas about car audio upgrades to find images and blogs about out of this world systems. Earth shaking bass installs and custom built fiberglass and Alcatara door pods. At Car and Home Stereo we can do all of this and more and of course they are beautiful to behold. Inevitably these sorts of installs come with a pretty high price tag as well, what if you just want to improve the audio in your car at a sensible budget? Well let’s look at a typical upgrade that provides a very big ‘bang for your buck’!

A recent install of ours was to a Renault Megane RS. This fabulous car is at home on road or track especially when ‘tweaked’ to over 400 BHP as this one was.

Unfortunately the stock audio system is quite frankly dire. The dreadful speakers are mostly to blame but the low power of the head unit certainly does not help as any attempt to squeeze out a decent bass response just results in hideous distortion.

This was what the owner had experienced and indeed had already replaced two of the speakers as they had failed. He realised they were never going to sound good so popped into the shop to discuss options.

Usually I get carried away when designing a system but fortunately the customer told me straight away that his budget was £1000, certainly for the first part but he would consider future upgrades. He also told me that his preference was for dance music, high energy and plenty of bass. However he was very keen to keep the look of the interior unchanged and did not want to lose the boot to a mass of amplifiers and subwoofers.

So what should we choose?

The front speakers are a 5 inch mid in the door and 1 inch tweeter on the dash. Space is an issue in the doors so nothing too deep but we needed something that would deliver a good mid bass performance from only 5 inch. I knew there would be an amplifier so power was not an issue. In the end it was an easy choice; the JL Audio C2 525 component set. JL Audio are the masters of bass, their subwoofers are legendary and they know how to engineer a speaker to get the best bass performance possible.

In addition the C2 tweeter is very lively and I felt would suit the dash location of the Renault Megane perfectly. Of course we would be installing Dynamat sound deadening to the doors to further enhance the speaker performance. The sophisticated crossover has a range of adjustments to allow fine tuning of the sound which is of great benefit as the factory head unit has very limited EQ controls.

Choices, choices…what amplifier to choose?

Budget and space was tight and I wanted the best possible sound for this car, I had to work with the factory head unit so needed something that could deliver a big punch from a compact unit. It had to be a 4 channel as it was also going to drive the subwoofer in the boot. I wanted a unit that could take a high level in and had plenty of control; step up the brilliant JL Audio JX 400/4D.

This powerful D class amplifier boasts 400W output with a host of EQ and filter controls allowing fine tuning of the sound output. It will take high or low level inputs with up to 10V capability on the high level, perfect. Another benefit is the size; the compact dimensions of this amplifier mean I can install it under one of the front seats out of sight. Channels 1 and 2 will drive the front speakers while channels 3 and 4 will be bridged to provide a huge mono output for the sub.

But what subwoofer should we fit?

Well as we knew the customer’s preferences and requirements it had to be compact but still deliver hard hitting bass. After checking that he was happy with the size in the boot we settled on the JL Audio CP108 microsub.

This is a high output, slot ported enclosure houses the 8w3 subwoofer and can punch far above its weight. The subwoofer itself is extremely good but when married to the JL Audio designed enclosure it is astonishing. When set up correctly you could be forgiven for thinking you were listening to a 10 or even 12 inch woofer.

So a simple system at under £1000 but one that plays loud and clear with no distortion and offers plenty of scope for future upgrades like Bi amplification and DSP signal processing.

The test was always going to be when the owner of the car heard it for the first time, I knew it was good but would he like it? At first listen he played the same CD that was playing when he dropped the car off at our workshop. After a second or two a huge smile spread across his face and remained there for about half an hour while he tried other tracks. ‘Absolutely awesome, exactly what I wanted’ as he stepped out of the car. He mentioned that he was taking the car down to the Nurburgring, Germany was going to sound good!

Improving the Mustang

The Ford Mustang GT, 5 litres of good honest, V8 muscle car.

The Mustang looks great from any angle and the rumble from that big lump up front is wonderful. Unfortunately the same can’t be said for the sound inside the car; the performance from the audio system is very weak. We recently worked on just such a car equipped with the Shaker audio system which, although fitted with an amplifier and subwoofer in the boot as standard, was distinctly lacking in performance.

As you may know I am an advocate of simple systems. The simpler they are the easier they are to control. Dozens of speakers does not automatically mean better performance where sound quality is concerned. A lower part count but of a better quality is much to be preferred.

The owner of the Mustang felt the same about the sound. After a discussion regarding his musical preferences he left the car with us for three days.

Choosing the system:

The first job was to assess the interior of the car for speaker and hardware locations and to listen to it to get a feel for the general acoustics both stationary and with the engine running. Try to work out where extraneous noise was coming from and gauge the sound stage from the seating position. The Mustang has six speaker locations in the front and two more on the rear deck; with an 8 inch sub in the boot. There is no spare wheel and the empty wheel well is spacious so ideal for amplifiers. There was also quite a lot of road noise in the cabin so we knew that a complete sound deadening treatment was required.

The audio performance for this car had to be spectacular, for me that meant A and AB class amplifiers for the main speakers with full active EQ control. I wanted detail and power in the front but also an all-encompassing performance from the whole cabin. I was instructed not to change any part of the car so that it could all be returned to standard so I knew I could only use an eight inch sub.

My choice of amplifiers had to be from the magnificent Audison Voce range.

I needed seven channels for a fully active system so that meant an AV5.1K and a Due. The beauty of the 5.1K is that channels 1 and 2 are full class A which is perfect to drive the tweeters. Channels 3 and 4 are class AB and ideal for the mid drivers. I had settled on the staggeringly accurate Rainbow Profi series for the front speakers and the Voce 5.1K would be the perfect partner. I opted not to install tweeters in the front A pillars as I felt they were too far forward to be of use and I knew I could tune the sound stage with the Audison Bit 1. This way all front speakers would be in the doors for the optimal imaging.

For the rear deck I chose the Hertz Mille Pro 165.3 coax. These are tight and punchy, perfect to complement the front detail. The Voce Due amplifier is very dynamic and again suits the performance I was looking for.

Since I was restricted to an 8 inch sub in the original enclosure I opted for the Hertz Mille Legend ML 2000.3. I have the same sub in my Discovery and know how much punch and performance this speaker can deliver. The 1000W from the sub stage of the Voce 5.1K amplifier will help as well!

Once the system had been decided upon it’s time to start work.

Initially we need to strip the car down to allow for cable runs and sound deadening treatment. This in itself can take a full day; as it is imperative that cable runs are safe and cannot cause rattles. A job like this requires a significant amount of cabling so we have to ensure that there is room under all the trim and all looms are protected and supported. Power cabling should be separate from any audio cabling where possible and of course carefully fed through grommets and sealed where passing through bulkheads.

Once I knew all the amplifiers and processor would fit in the wheel well I set about sound deadening the area.

This is made easier with all the trim panels out and will really help to reduce noise but will also improve the sub performance as no acoustic energy will be wasted into the resonant panels. Although the picture does not show it the treatment goes right up the side of the boot area onto the rear wing panels.

I also treated the rear deck as this can easily resonate with the extra energy we are generating in the speakers. I also built new wooden speaker collars to replace the standard plastic ones. This helps to isolate the speaker from the resonant metal deck.

Next Steps:

Once the rear treatment is complete I could start to manufacture the panels to support the hardware. Even though this can’t be seen I like to make this a perfect fit and trim it to look like the original.

This shot shows the initial setting up of the processor and amplifiers. This process tells the system where the input signal is coming from, what speakers are installed and allows me to set up the initial crossover points for the speakers, fine tuning will take place at the end of the install.

Now my attention turns to the front doors.

The Rainbow Profi speakers are quite simply stunning, their accuracy is very close to perfect so careful installation is essential. This of course means a full sound deadening treatment inside the doors as well as making wooden speaker collars and supports. Although not shown we also apply foam speaker rings around the mid and tweeter drivers. This helps to ensure an acoustic seal to the door card.

Great care is taken to ensure everything is moisture sealed to prevent any damp getting to the door card.

As I mentioned earlier, we were to use the original subwoofer enclosure to keep the car looking standard. This enclosure was manufactured from plastic so needed significant treatment to improve its acoustic properties. This was accomplished by lining the interior with copious amounts of sound deadening and adjusting the internal volume to suit the Hertz Mille Legend driver.

With all the trim panels back in place and a grille on the subwoofer the car looked almost standard. We did install the Bit 1 controller in the centre dash below the radio for convenience but even here the chrome finish and blue illumination looked perfect.

So how did it sound after tuning?

Well words can hardly do it justice. The image was high but surrounding with everything placing exactly where it should be. The sub was powerful without being obtrusive and a perfect blend with the front speakers. The Profi speakers benefit from an extended run in period but even initial performance was stunning. Playing my usual suite of test tracks demonstrated amazing clarity and detail; I use Eva Cassidy’s Fields Of Gold as a test piece and in this system her voice is sublime. This is one system I could listen to forever without any stress.

Drive Safer this Winter

I’m sure it has happened to most drivers; you’re happily driving along listening to your favourite music when out of nowhere you hear sirens along with flashing blue lights. You know you have to slow down or pull over but there’s nowhere to go and the panic sets in. Well maybe not everyone and not so dramatically but wouldn’t it be great if you could have advanced warning of the approach of any police or emergency vehicles? What would be most useful would be a device that could detect the approach of any marked or unmarked vehicle giving you plenty of time to react as necessary.

Introducing the Target Blueye:

This very sophisticated device monitors the Tetra radio bands that all emergency vehicles in the UK

currently use. It can simultaneously detect up to 200 channels at the same time meaning it will never miss one while scanning. Target Blueye will operate at up to 1Km range; allowing plenty of time to make sure you are not caught unawares. Because Target Blueye only monitors the Tetra carrier waves to detect proximity and in no way intercepts communications, it is entirely legal.

While we in no way endorse speeding the video below demonstrates how Target Blueye works.

As you can see from the video; the display alerts the driver to an approaching emergency vehicle in plenty of time for the driver to pull out of the way. This could be police marked or unmarked, ambulance, fire engine, motorbike or helicopter.

If you would like to know more about how this system works or would like to book in for an installation please call us on 01625 432707.

It seems almost every day we hear of another road rage event or reports of dangerous driving. Often these events have only one witness, the driver. So it makes sense to install a high quality witness recording camera. A good witness or dash cam will continuously record both front and rear of the vehicle; meaning any event will be captured and may be used as evidence. It should also have time, speed and location information as well as G shock measurement to indicate the severity of any impact.

One of our favourites at Car and Home Stereo is the…

Titan 2 from Virtus Fleet:

This powerful package is neat and fully automatic. Images are recorded to an SD card of up to 128Gb meaning a lot of information can be stored. Any significant shock events are stored in a different file that is automatically saved. All data is encrypted which means it can be used as acceptable evidence for legal purposes. Parking mode is on by default so it will wake up if there is any interference with the vehicle. It also monitors battery levels so there will be no problem with running the car battery down if the vehicle is left for an extended period. For leisure or commercial vehicles there is also a heavy duty external rear camera available.

The Titan 2 may cost a little more than some cameras out there but the high quality of these units makes them extremely good value.

Reversing cameras are brilliant as a parking assist. Warning tones are great but there is no substitute for actually seeing what is truly behind you.

Many cars these days have a screen built into the dashboard but many are not equipped with a reverse camera. At Car and Home Stereo we can often integrate a reverse cam to the factory screen; which will work just like the original equipment showing the image as soon as reverse gear is engaged. This allows for greater safety and accuracy when parking and saves a lot of strain on neck muscles!

If you would like to know more about any of the safety features we can fit to your car please feel free to contact us on 01625 432707 or pop into our shop on Sunderland Street in Macclesfield.



The stages of Car Audio upgrades

When a customer comes in for advice about an upgrade to their audio system we go to great lengths to ensure we get a good understanding of what they want. What sort of music they listen to, how they like to listen to it, what sort of staging they like and so on. Once we feel we have enough information then we will start to design a system for that particular customer and vehicle. We will probably suggest two or three options of varying performance levels but almost all will contain the same fundamental setup of processor, amplifiers, speakers and subwoofer.

Of course we have to make sure that everything will fit and be as discreet as the customer wants but that is something where our experience and knowledge of different vehicles comes to play. Depending upon the level of performance required we will design the appropriate interconnect system and recommend the amounts of sound deadening and acoustic treatment to make sure we achieve the best possible sound.

What about costs?

Only after all the system has been designed will we start to discuss costs as we will have a very good idea of how long the install will take and exactly what components are needed. In my opinion it would be very bad to start a system only to find out we need to add something and inform the customer of the extra cost during the installation, much better to know from the start.

The final figure can be quite high as you can imagine and sometimes the ideal system for our customer may be too much to afford all at once. So now there are two choices, either compromise the desired performance and settle for a simpler system or split the ideal installation into manageable stages. We would almost always advocate the latter. It might take a little longer to achieve the final result but the when you do it will be exactly what you want.

So how do we split it up?

To a certain extent this will depend on the system and the car but what we want to aim for is a huge leap in performance with every stage. We like to see a big smile after every upgrade!

Let’s take a recent customer who has just had the last piece of his design installed. His car is a 1 series BMW which came with the basic audio system installed. He is a younger customer who likes a wide range of music but particularly enjoys dance music and to play it at a fair volume. He is critical in his tastes and really appreciates good sound. When he first came to us nearly a year ago he had just got the car and hated the sound system but wanted to retain the looks of the dash. After the initial discussions we recommended the following upgrades; Audison Bit 10 processor, Hertz HDP5 amplifier, Rainbow BMW specific speakers and Audison slimline sub enclosure. Total installed cost was a little over £2000.

Unfortunately the owner was not in a position to upgrade the whole car audio system in one go so we suggested the split route. The obvious first step would be the speakers and even here we can break it down into two separate parts, the doors and the under seat bass speakers. We suggested the doors should be first which was what he did which improved the front sound stage immensely.

As I recall it was only a month or two before he came back to have the under seat bass speakers replaced as he could hear that they were letting the sound down. Once again the improvement was marked with tighter bass response.

So what next?

Well the customer really wanted more bass and since that would need the amplifier we recommended that he add the sub and amp at the same time, quite a large investment. The additional benefit though was that the amplifier would be driving the speakers as well as the sub so there would be a massive improvement for all the sound. This must have been about 8 months ago so the initial expense of the car had been forgotten and our customer went ahead. You should have seen the smile on his face when he turned it on for the first time! The sound had been completely transformed now that it wasn’t dependant on the BMW head unit.

Added Extras:

For many people this would be enough but we knew it could be even better so last week we fitted the last part of the plan, the Audison Bit 10. This required tuning and we could really set this up properly as all the speakers were well run in. Adding the processor and tuning really lifted the sound stage and brought the bass response right into the cabin by careful use of the time alignment function. Again there was a huge smile from the customer, he could hardly believe it was the same equipment the change was so pronounced.

So it took nearly a year to achieve but by sticking to the original plan this BMW sounds absolutely amazing. It would be so easy to compromise the performance by getting cheaper equipment installed all in one go but with a little patience you can have the car audio system of your dreams.

If you would like to know more about how we can improve the audio in your car please call me on 01625 432707 or better still pop into the shop on Sunderland Street in Macclesfield. I hope to see you soon.

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!

Latest Products from Bose.

Sorry to bring up the ‘C’ word but that time of year is fast approaching. Of course, if you’re anything like me then gift shopping might not start until December 24th but for the better organised of you, it is worth a look at the Bose range of audio systems now.

There some new additions to the range this season and they always seem to fly off the shelves so getting in early will ensure you are not disappointed.

The first of the new products is the super cute Soundlink Micro Bluetooth speaker.

Just released, the Micro is part of the Colour range and this one is truly rugged. The integral flexible strap means it can be attached to just about anything and the weatherproof design means not having to worry about getting it wet. With built-in Siri and Google assist compatibility you can control your music without picking up your phone and of course for taking calls on the go the Bose Soundlink Micro has speakerphone capability.

Like all Bose sound systems, this one sounds fantastic and is designed to give a rich, powerful performance even when outside while still delivering impressive battery life. This is all the more impressive when you consider the price of only £99.99. Available in black, red and blue we carry stocks of all three but hurry, I’m sure these are going to be extremely popular.

The original Soundlink colour was incredibly successful because of its performance, rugged build and long battery life, the Mk2 version takes all of that and improves upon it. Now with Siri and Google assist compatibility control is even easier while the voice prompts mean pairing and setting up is a breeze. Control can be further enhanced with the Bose Connect app for Apple and Android devices.

All this for £129.99 makes the Bose Soundlink Colour incredibly good value for money.

Soundlink Revolve & Revolve Plus:

The original Bose Soundlink Mini redefined how good a Bluetooth speaker could be and was the biggest selling portable Bluetooth device for a long time. That unit has now been retired and has been replaced with the Soundlink Revolve and Revolve Plus.

The Mini was unbeatable indoors but a little less so outside so the engineers at Bose set out to improve this. The result was a completely new design and the most striking feature is the full 360 degree sound delivery. This technology has come straight from the top of the range Bose Lifestyle system where a fully immersive surround sound performance was required.




By placing the driver vertically there is no directionality to the sound meaning everyone around the unit gets the full experience. I can vouch for this personally as my Revolve + in the garden is astonishingly good.

Battery life is equally impressive with up to 12 hours available from a single charge. Again they are rugged with shower resistance and of course full compatibility with Siri and Google Now. Control convenience is further enhanced with voice prompts from the unit and compatibility with the Bose Connect app.

The Revolve comes in at £199.99 while the Revolve+ is under £300 at only £279.99. Both are available in silver or black.


That concludes the Bose Soundlink line up, all of them are mightily impressive but which one is right for you? If you would like to know more then please call us on 01625 432707 or call in for a demonstration at our shop on Sunderland Street in Macclesfield and remember we will always try to match any genuine price.


Volkswagen Passat Car Audio Upgrade.

A modern car typically comes with a fully integrated multi-function entertainment system. This will usually provide satellite navigation, full Bluetooth hands-free calling and music streaming along with a comprehensive vehicle information display. It is quite unlikely that you would want to change this system as it provides all the functionality and is aesthetically pleasing. Unfortunately, the sound reproduction from these units and installed speakers can range from mediocre to downright poor, so what do you do to improve it?

A perfect example of how we set about improving a car audio system is demonstrated by this Volkswagen Passat Alltrack we had in recently. The owner was extremely happy with the car, his job meant he spent a lot of time commuting and as he lived off the beaten track the 4 wheel drive was essential. However, he was less enthusiastic about the fitted audio but since he had been to us with several cars in the past he knew we could help.

As a returning customer I already knew his musical tastes, I also knew about his hearing. He loved music in all its forms from hard rock to opera; country to jazz; hip-hop to soul and everything in between, unfortunately, his ex-military background had left him with a reasonably severe high-frequency hearing loss from weapons fire. I had to design a system that was capable of delivering a powerful performance whatever the demand and make sure that it could be tuned to compensate for his particular needs.

The design process;

The first consideration has to be the customer and since I knew that this car would need careful tuning there would have to be a digital signal processor. The standard audio in the Passat is only a simple 4 channel system and I knew we would be installing a subwoofer so again a signal processor could be used to develop the subchannel. My choice would be the Audison Bit 10.

This versatile device is able to connect to any non-digital car audio head unit. With up to six input channels, five output channels and a very powerful DSP suite on board it is the perfect solution for a simple system.

The software allows me to create a map of the system installation and most importantly tune every single speaker to perfectly balance the sound. Then I can start to add the specific requirements for the individual customer’s requirements.

Of course, before we get to the tuning stage we have to choose the amplifier and speakers. Again knowing my customer helped as I knew what I would have to get from the speakers. His particular requirements meant that I would need a tweeter that could deliver a higher than normal performance without getting harsh or shrill and I knew that he would like to play the whole system loud. Initially, I thought about the Audison Voce K6 which is one of my favourites. This is a fantastic speaker set and is incredibly smooth however I felt the tweeter may not quite suit the way I would need to set this system up. I also wanted a door speaker that would be happy with an extended low-frequency response to again suit my customer’s requirements.

I finally settled on the Hertz Mille Pro MPK165 for the front doors.

This speaker set was ideal; the main driver has a large over roll allowing a great excursion while the sensitivity ensures that no detail is lost in the midrange. The tweeter is a gem that loves to deliver and has no problems at higher power levels. Of course, I treated the door to a generous coating of sound deadening to further improve the acoustics. We also make sure that there can be no moisture ingress by sealing the custom collars and speaker basket with silicone.

While the Passat has a large load area the owner did not want too much space taken up as it was a working vehicle. Of course, we still needed to deliver an exciting bass performance and we quickly decided on the Audison APBX 8.

This compact unit is an absolute powerhouse delivering tight and punchy bass at up to 500W. This can be seen from the installation photograph it really is discreet.

Now that the processor and speakers had been decided upon we just needed to choose the amplification. Fortunately, there is a good space under the boot floor in front of the spare wheel; we opted for the JL Audio RD 900/5.

This five-channel amplifier can provide ample power for the whole system; and also allows for a cabin mounted bass control which is essential as the VW head unit has no sub control.

How did it sound?

Initially, I tuned the system to my standard reference for the vehicle. Although the speakers would need a good few hours to run in the initial performance was excellent. My reference Michael Jackson CD sounded fantastic with punchy bass and very clear mid and top. Next, I started to add the modifications required for my customer. I enhanced the power above 3 kHz to compensate for his hearing loss and extended the low frequency in the main drivers to deliver the extra punch he preferred. Because of the extra high frequency, I carefully adjusted the time correction so that it didn’t all appear to be coming from the driver’s side tweeter.

The final sound still needs to be adjusted to taste once the speakers have run in but the initial reaction of the owner was one of delight. It would probably sound over-bright to must people but it worked beautifully for this customer. That’s the beauty of adding a sound processor in that we can tune it to precisely your exact tastes and requirements.

We love to get this right and it gives us great satisfaction to see that big smile from our customers when they hear it for the first time.

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.

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.

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!
