Tim on Driving Sounds Magazine

As the UK’s only specialist car audio magazine, Driving Sounds aims to bring this niche industry to the attention of a wider public by promoting good sound in cars.

Good car audio is not only about equipment but also about the way it is installed which makes the industry unique. In most cases a system is sold complete with installation expertise, which is required to ensure that a vehicle’s standard functions and systems are not adversely affected.

Driving Sounds Magazine presents readers with reviews of vehicles that drivers have had audio installs fitted to. There are product reviews, installer features and also simplified explanations of what bits of a technical specification and features list are important to the final sound and which are simply marketing noise.

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.

Demonstration of Distortion

An interesting situation occurred at Car and Home Stereo recently that I would like to share. It highlighted a phenomenon that is quite counter intuitive and led to some interesting discussions.

We have a demonstration Land Rover Discovery that has a simple, high quality audio system installed that is tuned to perfectly suit the interior acoustics. We always encourage our customers to sit in and experience it as it shows what can really be done with car audio. The amplifier that powers the system is the magnificent Audison 5.1K which develops a true 1650 Watts.

There is one pair of component Hertz Mille Legend speakers in the front doors and a Hertz Mille subwoofer in the rear.

A customer recently auditioned the system and we spent a good hour playing different types of music with a view to producing something similar in his car. He was completely blown away with the sound, couldn’t believe the clarity and how the sub blended perfectly with the whole system. And then he said ‘I love it, but it’s not very loud is it?’. In fact he reckoned his standard Ford system was louder!

Now I know just how loud our system is and the odd thing is that the cleaner the sound the less we perceive volume. Since we had some time I decided to run a little proof experiment with my customer’s car.

As part of our equipment set we have an industry standard spectrum analyser which is also equipped with an SPL meter. It was a simple task to set this up in the Discovery first and then the Ford to compare. As expected our Discovery hit 126dB easily, the Ford however struggled to hit 110dB. In real world terms this equates to a perceived doubling of power (a true doubling is 3dB but we don’t really hear it that way). The next test was the distortion level. By plugging an oscilloscope into the amplifier output we can measure the clipping levels. Unsurprisingly the Discovery registered less than 5 percent distortion at full volume as this was how it was set up. However the Ford reached 5 percent at a little over half volume and climbed to over 25 percent.

There is no arguing with the figures so what is going on? Simply that the higher  distortion levels were being registered as unpleasantly loud and our brains are trying to get us to turn it down! Distortion is the quickest way to destroy a speaker or indeed your hearing.

At Car an Home Stereo we value our customers and hope to be providing high quality audio systems for many years. A distorted sound system will very quickly do serious harm to our hearing and that is why we only choose the best equipment and like to carefully set these up to give the best possible sound. Brands such as JL Audio, Audison, Hertz and Dynamat may not be the cheapest but certainly are amongst the best. The fact that when installed correctly they can deliver an amazing sound makes them excellent value for money.

As to my customer with the Ford, he now has a fabulous system based around a JL Audio amp and speakers with a Rainbow active sub. He loves to play it loud and I know it will give him years of pleasure without doing any harm.

What To Look Forward To In 2017

It’s good to be back after the festive break and there is a lot to look forward to in 2017.

World renowned audio manufacturer Audison have just announced their new Thesis speaker range. The Thesis amplifier represents the absolute pinnacle of performance without compromise and now there is a speaker set available to match. If you are looking for the absolute best possible sound then this is it.

Staying with Audison, the new slimline Prima subwoofers and enclosures offer stunning bass performance from a very compact form. These will appeal to anyone who does not want to sacrifice much boot space but still demands a Hi-Fi response.

There will also be a new Prima Pack custom installation kit for the BMW 1 series. This car has always had a very disappointing standard audio system and the Prima Pack is a tailored solution comprising the stunning AP amplifier, a custom Prima speaker pack and compact subwoofer. As with all the Prima Pack systems the factory head unit remains unchanged but the audio performance is greatly enhanced by the AP amplifier. The speakers fit perfectly into the factory locations and the sub is designed to blend seamlessly with the factory trim.

On the other side of the Atlantic, JL Audio have released their amazing new processors, the new Fix and TwK.

The FiX range is simplicity itself to use and automatically deals with all the anomalies inherent in vehicle factory head units. Building on the success of the CleanSweep processor, the FiX can automatically de-equalise audio streams and can even remove spurious time alignment errors giving  a flatter, more open sound from which we can build a better audio system.

The new TwK processors take this a huge step further by allowing access to a vast range of processors via the JL Audio software. From input/output configuration to full spectrum equalisation, this product means that every installation can be tuned to perfection.

Over the break we have been busy building new demonstration stands to showcase some of our best car audio equipment as well as tweaking our Land Rover Discovery demonstrator. This simple car audio system still astonishes me with its clarity and power showing what can be achieved with just one pair of speakers, a subwoofer and amplifier. If you haven’t heard it and can come down to our shop on Sunderland Street in Macclesfield I would encourage you to do so, it is sure to impress.

Our focus, as ever is on installation of the highest quality whether it is a simple dash cam or a full blown custom audio system. We are proud to be a part of the national FourMasters group offering the highest installation standards and a three year warranty on installations.

Please feel free to pop in or give me a call on 01625 432707 to discuss ideas and start your journey towards 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.

Christmas ’16: In Retrospect

As we come to the end of another trading year it seems fitting to look back at what has changed for us. Personally I think the development of affordable and powerful Digital Signal Processing by Audison has been a complete game changer. At Car and Home Stereo we have always embraced any new technology that will improve the in car audio experience. I can remember fitting Phoenix Gold analogue graphic equalisers in the 90s and spending ages carefully setting them up for the vehicle acoustics. Then the customer’s ‘expert’ mate would have a go, dial in the ‘smiley face’ EQ curve and ruin the sound.

When digital systems started to appear I was delighted as there were no more sliders to get fiddled with. I was one of the first to install the Phoenix Gold TiDEQ and it was brilliant if not tearfully expensive. Inevitably, cheaper systems appeared from other manufacturers but they were short on processing power and were distinctly underwhelming.

Fortunately Audison picked up the baton of digital signal processing and ran with it.

With powerful software and a host of automatic and manual signal conditioners on board, the Bit range of products now allow me to take any car and be confident of a stunning audio result, regardless of system installed and at a more than reasonable cost.

Another one of my favourite company is JL Audio. Their range of subwoofers and amplifiers are almost unmatched for performance and fidelity. Ten or more years ago we were installing plenty of subs but they were large and needed large enclosures for the best sound. This meant eating up lots of boot space, many customers just did not want that and so compromised on the bass performance. JL Audio, already masters of subwoofer design, set out to help everyone get the best bass performance regardless of available space. In the last couple of years they have produced some spectacular speakers that will operate in almost ridiculously small enclosures. Their TW range particularly so. At Car and Home Stereo sound quality is our first consideration and adding a subwoofer is to my mind essential, now we have the products to allow this regardless of space.

Another product that has really impressed me this year is the SoundTouch 300 soundbar from Bose.

This very stylish soundbar not only looks fantastic with its black glass top and minimal design but it has a sound that will quite simply amaze. As one of the undisputed leaders in sound reproduction technology Bose have delivered a product that defies reality. Although it is only a single bar it manages to create sound from places far beyond its size. Close your eyes and you will be convinced that there are speakers all round you! If that is not enough then you can also add the optional powerful subwoofer and even wireless rear speakers for a true surround sound experience. Of course it also contains the Bose SoundTouch technology which is just about the best music streaming system available today as the icing on the cake!

And if you are stuck for a last minute Christmas gift, the Bose SoundLink Mini is perfect.

Don’t be fooled by the diminutive size of this little Bluetooth player, the sound is amazing. Full portability thanks to its long life rechargeable battery and a rich, full sound whether on its charging cradle or taken on an outing.

All that remains is for us to wish you a happy Christmas and New Year. Here’s looking forward to 2017 and all the exciting developments that are on their way for car and home audio.

Please note that we will be shut for the Christmas holiday from December 25th until January 3rd. Have a happy and musical Christmas!

Upgrading the Defender

The Land Rover Defender is a true British classic design. Although, now sadly out of production, the longevity of the Defender means that they will be on (and off) our roads for a great many years to come.

landrover defender stock

It’s design hasn’t changed much in its 70 years and, despite continuous improvements to comfort the audio, performance has always been poor. A relatively noisy environment coupled with small speakers has always meant the sound in the Defender has a lot left to be desired!

As Macclesfield in Cheshire is a fairly rural community there are a lot of these vehicles about as you can imagine and over the years I have developed an audio upgrade package which is powerful and discreet.

The first challenge is the speaker size. Being only 10 cm without modification means that the bass performance is limited. Step forward JL Audio! As the undisputed leaders in subwoofer design, JL Audio are perfectly placed to design speakers that have a much better bass response. This is not to say that a 4 inch speaker can replace a subwoofer but JL Audio’s expertise means that you will get a massive improvement over the stock speaker.

c2 400 subwoofer

To bring the bass response up to the required standard we need to fit in a subwoofer. The irony is that although the Defender is a large utility vehicle, there is almost nowhere to discreetly install a sub box without compromising useful space. JL Audio is here to the rescue, again, with their amazing sub, the 6w3.

jl subwoofer

This astonishing unit is a true 6 inch subwoofer. It is optimized for a tiny enclosure of just 0.125 cu ft. I have developed a carpet trimmed speaker box that will fit just under the roll cage bar behind the front seat. One can be used but for best results we recommend one either side to create an effective 12 inch sub. This allows for a much smoother performance and really blends with the music.


So now we have a sub we are going to need an amplifier. Again, space is limited but fortunately there is room under the driver’s seat for a compact unit. It makes no sense to just amplify the sub so we always install a multi-channel unit to power sub and speakers.

Here we must address the acoustic issues in the vehicle because of the speaker layout and the rather boxy interior of the Defender the sound staging is challenging to say the least. It is essential to install some sort of signal processor or regardless of the quality of the installed equipment, the sound stage will be poor.

I now always use the Audison Prima AP9Bit amplifier. This amazing unit has a full digital signal processor coupled to a powerful 8 channel amplifier in a very compact chassis.


This amplifier can be configured in any way I need depending on the complexity of the installed system. In the Defender it can be a 5 or 6 way for one or two subs. I can then configure the signal processor for the car acoustics and the personal musical tastes of the owner. The software is very powerful, providing  full spectrum equalization on every channel with very fine time alignment available to place the sound stage where it needs to be.

As a musician I can appreciate the subtleties of sound and this software allows me to bring out the finer details of the music even in a challenging environment like the Land Rover Defender. I am often challenged by owners who say you can’t get a good sound in a Defender but I guarantee that I can. I have installed many of these systems now, both for private individuals and for local dealerships, the feedback is always the same, that they just can’t believe how good this sounds. One customer even came back to tell me that the sound was better than in his Bentley GT!

It is true that the kit described above is extremely good but without the ability to carefully tune it the results would be arable at best. That is where I can make the biggest difference, my experience and exacting standards mean that this great equipment can be enjoyed to its true potential and I feel that this is true value.


Whatever you own, Land Rover, Lamborghini, Lotus or any other car with a challenging audio performance I can make it better, give Tim a call on 01625 432707 or email sales@carhomestereo.co.uk to start your journey to better sound.


The Unsung Heroes of Radio

Aerials, the unsung heroes of radio!

They may not be glamorous or sexy but your aerial is arguably the most important part of any radio system. It is the link between the station transmitter and your car radio and without it the best radio receiver in the world is going to be silent.

This is particularly true for modern DAB receivers. Digital radio is still broadcast on the FM waveband but the signal is now just a string of 1s and 0s instead of a modulated analogue signal. This transmission method means more stations, more data, better sound and clarity. There has been an explosion of content providers keen to use this digital media rather like we saw when digital TV started.

Despite the many advantages of digital transmission, there is one major drawback, the fact that it is either fully available or not at all. That is to say that if reception quality falls then the signal completely disappears. With an analogue FM signal if the signal strength dipped then all that happened was a slight interference or a drop to mono, DAB on the other hand will ‘bubble’ and disappear, usually just when things are interesting!

So let’s concentrate on DAB aerials as they are crucial to good reception. Most DAB radios are sold with an in windscreen aerial.


Let me say now that these are the least desirable type. They work but at a very low gain which means that in weaker signal conditions they will fail. Of course, a lot of modern cars have no external aerial and you may not wish to install one so these stick on aerials are your only option. Some are better than others and at Car and Home Stereo I have tested as many as I can find. The one I use is the most successful one to date offering reasonable reception under most conditions. This is not to say it is faultless and it still suffers from directional issues which are to say a station can be clear when travelling to work but poor in the opposite direction.

For best reception there is nothing better than an external aerial. Since DAB radio is broadcast on the FM waveband it is perfectly possible to use a standard aerial as fitted to the roof of some Fords and wing mount on Land Rover Defenders. All that is needed is a modulator to separate the two signals.


These can offer up to 10 dB of gain for both FM and DAB which means a great reception for both.

Unfortunately the modulator cannot be used with existing amplified aerials as fitted to many cars.


These vehicle aerials strip off the higher frequency signals before sending to the radio so no DAB. In these cases I always prefer to fit a replacement combined FM/DAB aerial.


These can again offer up to 10dB of gain and of course suffer no directional issues. If your car has navigation then there is a version of this aerial that also contains a GPS receiver. The mast is removable and the look of the car is unchanged. I have often fitted this aerial to cars with no external mast like the Volkswagen T5 and the reception is dramatically improved.

As I said at the start, aerials are not glamorous but getting it right will mean trouble free reception and less annoying drop outs.

Simon Says? Speakers Please!

For this instalment let’s look at speaker installation. The speaker is the last piece of hardware between your music and your ears and as such has an awful lot to do with the sound you hear.

The science behind the speaker is extremely simple; pass an electric current through a wire that sits inside a magnetic field and the wire experiences a force, vary that current and you vary the force. Of course this demonstration produces no sound but if we attach the wire (or coil) to a diaphragm (or cone) we have the nucleus of a working speaker. The electronics in the amplifier produce the varying electrical current and the speaker responds, creating the highly complex vibrations in the air that we hear as music.

The above description is of course highly simplified and in reality there are many more aspects to speaker design. We have to consider the weight of the moving parts, the resistance to movement within the materials themselves, the linearity of the magnetic field, the quality of the coil wire, the damping to prevent uncontrolled excursion, stability of the frame and so on and so on! Fortunately all of these considerations are engineering problems and this means that better engineering will lead to a better product.


When Mr. Ford or Mr. Audi or even Mr. Porsche are told that they have to put speakers in their cars their first consideration is not about quality even when they enlist the help of respected Hi-Fi companies. Their overriding concern is one of reliability. A blown speaker is a warrantee issue and that costs money. The trouble is that a speaker that can survive heavy metal hard core country rap at full volume has to be made super resilient. This speaker is not going to be able to respond to the subtle nuances of any quality musical performance.


At Car and Home Stereo we are always going to install a high quality speaker, carefully selected to match the vehicle and musical tastes of the customer. This is where our installation skills are needed. The average car door is a challenging place for a speaker. It is a steel box that is often wet inside, can be freezing one day and very hot the next. There are moving parts within it and it is subject to a large amount of vibration and noise. Let’s look at a typical installation addressing each point.

First of all we carefully remove the inner trim making sure that all clips and seals are retained. After this the next job is to treat the metal skin with sound deadening material which will absorb road noise and any vibrations within the door.


Particular attention is paid to directly behind the speaker as this will absorb the sound generated by the back of the cone and prevent reflection back into the door panel.

Once the outer skin has been treated we apply a foam barrier to the inner skin. This forms a watertight seal and acts as a thermal and acoustic barrier. This keeps the car warmer in winter, cooler in summer and again reduces road noise. The difference these treatments make to a car is astonishing.


Now we come to installing the speaker. The factory units are often built to fit so we must make panels and collars to allow a perfect fit to the door.


It is very important that no moisture gaps are left as it may come as a surprise to know that doors are designed to let rain flow through them. Any gaps could lead to a wet floor so we make sure everything is sealed with high quality silicone, both the collar and the speaker, this also ensures no air gaps to compromise the speaker performance.


Quite a lot of work but absolutely worth it. These Audison APK speakers sound great anyway but by treating the door they are at least 30% better.
