Campervans: Upgrades and Audio Systems

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

Keeping it quiet:

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

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

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

Finding your way:

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

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


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

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

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

Reverse with confidence:

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

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

Sounds fantastic:

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

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

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

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

Don’t wait:

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


Summer Is Here!

Summer is here (at least for the next few days). So what could be better than driving your convertible with the roof down at last? So good to feel the wind in your hair, not so good if you want to listen to your music. What used to sound great with the roof up is now hollow sounding with a weak bass response and turning the bass up just makes everything muddy sounding. This phenomenon also occurs with the windows wound down on a conventional car to a slightly lesser extent. So what’s going on and how can we fix it?

As we know sound waves are just compression ripples in the air, in a car these waves are generated by the speakers and when the air is still and contained in a small cabin we do not need much energy to get a decent sound level. However, if we create large holes in the structure by opening the windows or taking the roof off we have opened the speakers up to the outside world. Suddenly your small speakers are trying to fill the world with sound; on top of that, they have to compete with more road and wind noise as well as all the air turbulence.

It would be OK if all frequencies were affected evenly and all that was needed was more power but unfortunately, this is not the case. Without getting into the technical reasons what we find is that the higher frequencies tend to be less affected but the mid-range clarity is lost and the bass is severely reduced. Try it for yourself, listen to a piece of music you know well while driving and then open the windows. It is obvious from the pictures above that far less sound is going to reach your ears.

What we need is to be able to adjust the sound to compensate for the changes brought about by opening the car. Certainly we need more power by adding an amplifier but more importantly, we need to be able to adjust the sound for the different configurations of the car so that it always sounds the same.

To achieve this we have a range of digital signal processors at Car and Home Stereo that we can configure and program to solve the problem. The two leading units are the JL Audio TwK88 and the Audison Bit family of processor/amplifiers. These powerful processors can be programmed to allow precise tuning of the vehicle acoustics and most importantly have multiple pre-set capabilities which allow the user to switch between different tunings for different conditions.

So how do we do it?

The process requires taking acoustic measurements with the vehicle roof up and down. The same can be done for a non-convertible car with windows closed and open.  We use a combination of spectrum analysers and FFT (Fast Fourier Transform) measurements to map the acoustic signature of the vehicle interior. By playing a test signal (usually pink noise) we can see what the placement of the speakers and vehicle interior is doing to the sound and of course, we can do the same with the car open.

Once we have the measurements we can start to tune the system. We start the process by adjusting time delays and phase controls to see if there are any cancellations being brought about by speaker positioning, we will also adjust speaker crossover points for the same reason. We do this first because no amount of EQ tuning would compensate for a phase issue and in fact, would probably make the sound worse. It also means less work for the processor which will ultimately give me more control. The goal is a clean, flat response to the test signal which we can use as a starting point for the real world tuning for the customer.

What’s Next?

Once we have the desired response for the car in the closed condition we look at the measurements for the converted configuration. The difference in the original measurements can now be compensated for by re-tuning the system and saving to a second pre-set. Once again we start with phase adjustments as with the top off there will be far less reflected sound and the speaker phase conditions will be different.

The result is the same audio performance for both configurations of the vehicle and at the touch of a button, you can switch between the two presets meaning great sound regardless of hood position.

We mounted the Audison controller for this Mercedes in the ash tray making it quick and easy to change presets but invisible when the cover was closed.

This tuning process is not simple and many different factors have to be considered as the adjustments are made. It also requires accurate and quite sophisticated measurement tools and at Car and Home Stereo we have invested in these to ensure we can achieve the best possible performance for our customers. We can also use these tools to identify acoustic problems in audio systems and we are more than happy to run a diagnostic on your car to help you choose the right way forward to better sound.

If you would like to take advantage of our test equipment or wish to discuss any aspect of tuning please feel free to call me on 01625 432707 or even better call into our shop on Sunderland Street in Macclesfield for a chat and a listen to our demonstrator.

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.
