Bentley and Mercedes audio upgrades

Modern vehicles often have very sophisticated information/entertainment systems built into the dashboard. In a lot of cases it would be just about impossible to change this and besides, why would you want to? They usually look great and offer large clear displays with all the features you could want.

A great example is the VW Golf 7.5. With DAB, Car Play, USB, navigation and vehicle information interface it has everything, except great sound and we can easily solve that!

Bentley Upgrade:

Whilst this is still a great car; older vehicles may not have all the features you want. Firstly, the entertainment system could do with an upgrade.

This may not be a simple task however as there may well be complications such as factory fitted amplifiers, steering wheel controls and dashboard information displays. A perfect example is this 2010 Bentley Continental. The car is absolutely stunning but the entertainment system is woefully out of date, the navigation is missing a great deal of new roads; there is no IPod / IPhone support; no music streaming and no DAB radio. There are however controls on the steering wheel for volume and modes, a rear mounted multi speaker amplifier and a screen that displays climate controls as well as vehicle information.

While we would like all the modern source capabilities we would not like to lose all the comfort features. Fortunately we have a lot of experience with these cars and have developed a fabulous solution. We can now seamlessly integrate new top of the range units to the Bentley to give you every modern convenience while retaining all relevant vehicle information displays using a state of the art, custom panel.

 

Bentley Continental or Flying Spur right up to date. As always anything we do can be reversed to return the car to standard trim at any time.

Mercedes Upgrade:

Another prime candidate for an upgrade is the Mercedes. These often come without Bluetooth or navigation and certainly no digital radio. Once again, here at Car & Home Stereo we have solutions for all types to bring them right up to date.

Adding these features adds a whole new lease of life to the car. Simple to use, elegant and seamless integration to the vehicle controls means you will enjoy all the luxuries of a new car without spending a small fortune.

Of course upgrades are not just for luxury cars and whatever you drive will benefit from our careful attention.

 

If you would like to know more about any of our upgrade options for your new or old vehicles please call on 01625 432707 or pop into our shop on Sunderland Street in Macclesfield.

 

Audi TT Audio Upgrade

The latest Mk3 Audi TT is packed with technology and has a very sophisticated infotainment system installed as standard (it desperately needs better speakers but that’s another story). But what of the Mk2 TT? Still a great car; but the old Chorus, Concert and RNS-E navigation systems are certainly showing their age. Regardless of whether it is equipped with standard or Bose audio the head unit is the same and is definitely lacking features and performance.

One feature that the later cars have is a multi-function steering wheel which incorporates audio controls. These are invaluable as they allow you to alter such things as volume and track without taking your hands off the wheel. When we upgrade the system we would definitely want to retain these.

Our most common upgrade to the TT is one the Pioneer multi-media navigation units. These very sophisticated entertainment systems feature DAB radio, CD and DVD, Bluetooth streaming and hands free telephone, Apple Car Play. They also include dual USB ports, reverse camera input and external video input/output.

We have all the appropriate installation items required for installation; so that all vehicle functions work properly. This includes steering wheel controls as well as neatly blending with the dashboard.

Audi TT audio upgrade

I think you will agree that this upgrade looks great and of course brings a whole suite of desirable features to the car.

Speakers:

With the head unit brought up to date it’s time to look at the speakers. Regardless of whether the audio system is base level or has the Bose option; the speakers have pretty much the same disappointing performance. On the positive side the speaker locations are good and the cabin is compact and quiet.

The simplest option is to just upgrade the front speakers. There are three speaker locations per side, two in the door and one on the corner dash. If the car is not already equipped with the smaller driver then the ‘grille’ in the middle of the door is actually just a solid cover without a mesh. If we wish to add these drivers then the appropriate part can be sourced from Audi. This then allows us to add a proper three way speaker system, one solution is the Audison Prima APK163.

What else?

We also like to add sound deadening treatment to the door to improve the acoustic response. The Audi door is well constructed but a generous addition of Dynamat or Skinz will dramatically enhance speaker performance.

Another option (and my preferred one) is to ignore the dash tweeter location and install a high quality two way system to the doors. Perhaps the magnificent Hertz Mille Legend MPK1650.3.

 

This is my preferred option as I prefer to keep the speaker count to a minimum. With a three way system there are by necessity two different crossover points; one for the bass / mid and one for the mid / tweeter. More crossover points mean more opportunity for phase errors to creep in if we use the standard passive crossovers with the kit. This can lead to poor definition in the image and sound stage. With a two way speaker system there is only one crossover point that is easier to control and thanks to the good speaker/listening position in the TT the staging works very well.

Amplifier:

Of course a great speaker requires a great amplifier to achieve the best results. Therefore, the standard Audi (or even the Bose option) amplifiers will never be good enough.

One of my favourite options is the Audison Prima 8.9Bit amplifier. This extremely compact amplifier is absolutely perfect. It is small enough to completely hide and is powerful enough to drive all the vehicle speakers. However, if more power is needed then a secondary slave amplifier can be connected alongside.

Of course its greatest asset is the very powerful digital signal processor on board. This DSP allows me to carefully tune the system for the optimum sound staging and personal preferences of the customer.

It also allows me to customise cross over points, time delay and phasing to ensure the best possible response in the car. Even better, if the TT is a convertible then I can tune two different performances; one for top up and one for top down. These tunings can be swapped at the touch of a button to ensure optimum sound whatever the configuration of the car.

Is it all worth it?

Naturally these speaker and amplifier upgrades are not cheap but consider this; if you were to opt for the expensive dealer audio ‘upgrade’ option then when you changed the car you would lose it all and you certainly would not get any of the cost back. In comparison everything I add can be removed and the original equipment reinstalled. This means you keep your investment and can have it reinstalled in your next car (and the next and the next…) and whatever the vehicle I can re-tune it for fabulous performance. I think this makes great sense and offers tremendous value for money.

If you would like to know more about how we can improve the system in your Audi TT or indeed any car please feel free to call me on 01625 432707 or better still pop into our shop on Sunderland Street in Macclesfield for a chat.

Digital Signal Processing

Well summer is fast approaching (hopefully) and that means we can finally get the car windows down and open the convertible hoods. While the fresh air and wind in the hair is nice, the open plan car has a dramatic effect on the sound quality from the stereo system. Even stationary, opening a convertible roof completely devastates the way your music sounds leading to a very disappointing performance.

What is going on of course is that certain frequencies are being lost to the outside world while some are retained inside the cabin. The result is usually a great loss of bass and mid-range while the treble stays fairly constant. This results in a very unbalanced sound that simple bass and treble controls cannot fix. However you do not need to suffer as we have the tools to make sure you can enjoy the same performance whatever the configuration of your car.

What we need are two audio systems, one for top up and one for top down. The top down system would need more bass and mid-range speakers with a less efficient tweeter. It would need more power than the top closed system to compensate for the losses and of course we would need to be able to switch between the two systems.

Of course the idea of fitting two different systems for different configurations is not practical but nevertheless it is what we need. So if we can’t do that what can we do to ensure great sound at all times?

The answer lies with signal processing and careful tuning for different car configurations.

Digital signal processing allows us to shape the sound to suit the environment. This is different to simply adjusting the bass and treble controls to suit the music as we are working to produce an accurate sound for the given equipment and vehicle. In addition most processors are equipped with two or more memory pre-sets that can be retrieved at the touch of a button. This effectively means we can have two (or more) different audio systems in one car.

There are many processors available today but which one is best? Well the truth is it’s the one that suits your particular system. It will depend on how many inputs and outputs are required as well as where those inputs are coming from. Are we integrating with a standard head unit or a vehicle’s factory amplifier? Are we to use analogue or digital signals? How many amplifiers are we connecting to? All these questions and more need to be addressed before we choose.

Of course the real power of any processor is its tuning capability and that can only be as good as the tuner!

Even a relatively simple system such as this in my Discovery can look daunting. All crossover points, slopes, levels, time correction and phase are accessible with the software and without a thorough understanding of what is going on it is very easy to end up with a terrible sound or at worst damaged speakers.

In the right hands these tools are extremely powerful. When I tune a system I can bring all my years of musical experience to the project. This means I can give you exactly the sound you want; regardless of how you use it or the configuration of your car.

If you would like a practical demonstration of what a well-tuned processor can do; please call into our shop on Sunderland Street in Macclesfield where I would be delighted to demonstrate our Discovery. It really is a revelation.

Improving the BMW audio

We have had a lot of calls recently from owners of newer BMW 1, 3 and 5 series vehicles complaining about the very poor sound quality of the factory audio system; even those with the Harman Kardon upgrade option. Some have described it as the worst sounding system they have ever heard! We have carefully listened to lots of these cars and can definitely agree. The bass is weak, the midrange is very confused and even where the optional tweeters are installed the treble is dull and lifeless.

Standard BMW speaker.

As if the poor speakers were not enough the problems are compounded by the head unit itself. Since BMW know that their installed speakers are of low performance the head unit is pre-equalised to prevent the user damaging them. This manifests itself as a roll off of bass as the volume increases; amongst other tricks such as reducing the treble when you think you are turning up the bass. All this adds up to a very disappointing performance with poor definition and a dreadful sound-stage.

But help is at hand. At Car and Home Stereo we have developed a 3 stage plan to improve any BMW audio system. All upgrades are specifically designed for the BMW and fit seamlessly with no changes to the vehicle interior. Each stage is a significant improvement and can be performed over time to spread the cost.

Stage 1; upgrading the speakers.

There are 6 speaker locations in the front of the BMW; tweeters either in the door or wing mirror position, mid speakers in the front doors and  bass units under the front seats. There will also be two speaker locations in the back of the car.

A stage one system replaces the front speaker set as we are always most concerned with the sound for the front of the car. If your vehicle is not equipped with tweeter locations then the appropriate parts can be obtained from BMW spares. While we can just replace the mid speakers, the tweeters add a tremendous performance boost.

There are quite a few manufacturers producing a BMW speaker replacement kit and we take great care to match the speaker set to our customer’s preferences. Not all the sets have the same characteristics and choosing the right one is important to make sure it suits the application.

We can install the speaker set in as little as 3 hours; we guarantee you will be very impressed. This upgrade may be all you need to satisfy your tastes, but in case you want even better, read on.

Stage 2; amplification.

This is where we can make staggering improvements. It is not enough to just add a simple amplifier because if we did then we would just get a more powerful version of the original signal. This is fairly pointless as we know the signal from the factory head unit is poor with all the problems mentioned above. What we need is a way to overcome those problems and that means we need a DSP, a digital signal processor. These are powerful equalisers that allow us to adjust the head unit output to correct the built in problems.

Ideally the processor and amplifier should be the same unit and fortunately there are a range of very high quality units available from Audison, JL Audio and others. Like choosing the right speakers it is imperative that we choose the right amplifier to ensure we can realise the perfect sound for our customer.

One of our favourites is the Audison AP8.9. This compact 8 channel amplifier/processor is capable of providing power to the whole car system. It can even be enhanced with the addition of dedicated slave amplifiers to increase the system power. The real strength of these amplifiers lies with the DSP. It allows me to carefully tune the sound output to perfectly match the acoustic requirements of the vehicle and the musical tastes of the customer.

A stage 2 system is worlds better than the original and is often enough of an improvement to satisfy; but of course there is an obvious final step…

Stage 3; adding a sub-woofer.

Although the under seat speakers are 8 inch drivers they should not be considered sub-woofers, they are really bass speakers, an attempt to get too much low frequency will drive them to distortion. If you want plenty of deep bass then there is no alternative except to add a boot mounted sub-woofer. That does not mean there has to be a boot full of large speakers. On the contrary, we have many solutions that are extremely compact. Again we will choose the best solution for your needs from Hertz, JL Audio and Audison to name a few.

So there we have it, three simple stages to audio heaven in your BMW. Don’t forget that all of this is removable and can be reused in your next car; try doing that with a factory upgrade!

If you would like to know more about how we can improve the audio in your BMW or indeed any other car, please get in touch. Call us on 01625 432707 or better still call into our shop on Sunderland Street in Macclesfield. We look forward to speaking to you.

Skyzack Guest Blog: What to consider when buying your first car

This week at Car & Home Stereo, we’ve got a guest blog from Skyzack LTD.

Skyzack LTD is a business support club based in Macclesfield. Their mission is to ‘help small and medium sized businesses become more visible while providing opportunities to young people interested in getting into business for the first time.’ This in mind, one of their team members, Aaron, would like to share a young persons perspective on buying your very first car.

What to consider when buying your first car:

When it comes to passing your driving test, the next big, exciting part is buying your first car! We would all love to jump straight into a brand new Mercedes, but let’s think realistically, there are many things we have to consider. From running costs to reliability, here are some of the most important things to consider when buying your first car as a young person.

Finance:

Many young people won’t be able to afford a Mercedes, so when it comes to choosing the right car for you; we have to think about the price, what is your budget? Are you buying the car out right or are you considering finance and spreading the cost over a few years? With finance there are many options you can take to suit your needs. For all finance types you will need some kind of deposit; the more deposit you have to lower your monthly payment will be.

Below is a list of the different types of finance you can get:

  • HP: Higher purchase is where you spread the cost over so many years and you own the car at the end of the finance. The monthly payments are likely to be higher depending on how many years you spread the cost over. For example, you can spread to cost from 1 year to 5 years.
  • PCP: Personal contract purchase is where you can suit the payments around your budget. When it comes to the end of the finance agreement, there are 3 ways you can go about it. 1: You can give the car back, 2: You can give that car back as a deposit for a new car, or 3: Pay the lump sum of what’s left to pay for the car.
  • PL: Personal lease is something perhaps not many young people will consider using. This is because a personal lease vehicle has to be returned in the same condition you brought the car in; otherwise you’ll be hit with a massive bill to pay for the damages and as a new/young driver it probably isn’t the best option.

Depending on how much you pay for the car, the year of the car and how long you want the finance the car for, each finance option is different. When it comes to buying a car from a well-established dealership, they will talk you through the best options depending on the car you want to buy.

If you are over the age of 18 years old, many car dealerships will have good deals on brand new cars on finance. There are even some schemes in place where you get the car, insurance, tax & car servicing is all included within the price of the finance and you just pay for fuel. For most young people this is a great idea as we don’t tend to think about road tax and having ours cars serviced often.

Overall, finance is a great way to be able to get an up-to-date car as long as you can afford the repayments!

Insurance:

If you decide against going for one of the many free insurance finance deals, you need to think about how you are going to insure your car. Insurance for young drivers has sky rocketed throughout the years. With an average of £2,700 for a young driver, this is certainly going to be one of the most important things to consider. How are you going to pay? There are 2/3 options.

Paying in full: This would definitely be recommended when paying insurance as it is the cheapest way to paying your insurance.

Paying monthly: Paying monthly is more expensive than annual as you are essentially loaning the money from your insurance company. This means you have to pay a percentage of APR on top of the insurance price. This is usually broken into a deposit and 10/11 monthly instalments.

Family/friends help: If you don’t have enough money to pay the full annual payments but don’t want to pay extra when paying monthly you could always ask a family member or close friend to pay the insurance in full then you pay them back using monthly instalments, that way you don’t have to pay the APR on top but you can still pay monthly.

How to get the price down:

Avoiding comparison sites is our recommendation; they do make the insurance search a lot easier, but more expensive. If you would like to get a general price you may end up paying then use a comparison site. However, insurers have to pay comparison sites commission, so it will bump up the price a bit. Most insurers will offer you a lower price if you get a quote by calling them. Adrian Flux states that 75% of their customers can receive a cheaper quote over the phone.

Buying new or second hand:

When it comes to buying a car, you’ll have to decide if you want to buy a second hand car either from a dealership or a private seller. Or you can buy a brand new car with the spec & colour of your choice. Buying a new car is great. You get a fresh car completely of your styling and choice to show off to your friends, but in the long run it may not be worth it.

As of 2014; 40% of 17 year old male drivers crash within their first 6 months of driving – itv.com. So if you are one of them, you would ruin your new pride and joy. And if you don’t have the correct insurance, you may be in for a hefty bill.

Gap Insurance:

You should definitely consider adding Gap insurance to your policy if you are going to finance a new car.

What is it? Gap insurance (Guaranteed Auto Protection) is the difference between the actual cash price of a vehicle and the balance still owed on the financing. When you take out finance, you pay more over the finance period than what the car is worth. For example, if you bought a car for £10,000 with a monthly interest of 6%, after 3 years you would have to pay £11,910 back through monthly payments. In the event of a crash, your insurance company would pay you £10,000 for the car value. Gap insurance would pay £1,910 for the remaining balance. Without gap insurance, you would have a written off car and still be paying £1,910 for it.

Used Cars:

Buying a used car, however, still has similar risks involved. Purchasing a used car will not give you the choice to have your own personal touch, unless you modify it and it may not be as reliable. Another issue involved is if you don’t receive a warranty, is the chance of your car breaking, potentially even 5 minutes from leaving the garage. If this happens and you have no warranty, there isn’t much that can be done. However if you manage to purchase a reliable used car, you will have a car that you can change to your taste and love like a new car, then in a few years’ time, you can go ahead and buy your dream car.

These are just a few of the main things you need to consider when buying your car and each choice is personal to you. Some of you may prefer a new car, some may just want a cheap run around. Either way, your car is your pride and joy. So go out there, find your dream car and be safe!

Whatever choice you make, remember that you can upgrade your car with Car & Home Stereo. Contact them today on 01625 432707. Or pop into the shop on Sunderland Street, Macclesfield.

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.

Sub-woofers:

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.

However…….

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.

If you would like to discuss how we can really improve your car audio please give us a call on 01625 432707. Or even better, pop into our shop on Sunderland Street in Macclesfield.

Find your way with Pioneer navigation.

The popularity of the motorhome has never been higher; the convenience of just being able to load up and drive away with all the comforts of home is priceless. One of the most popular vehicles for conversion is the Fiat Ducato. It sports a great chassis and a powerful, efficient engine. The only drawback is the fact that the Ducato starts life as a van, meaning a very basic audio system.

Perhaps the most useful feature to the driver of a motorhome is navigation; over the years we have added this feature to many vehicles.  As the dashboards have changed we have sourced installation kits to allow fitment of aftermarket units and this has proved more than acceptable. We have frequently used Pioneer products as they offer the best performance and although powerful and feature rich are exceptionally easy to use.

Fiat Ducato:

Well now Pioneer have extended their magnificent Evo range of bespoke navigation/entertainment systems to include the Fiat Ducato.

The first thing you notice is the perfect fit as this has been designed to integrate seamlessly with the Ducato dash. The large 7 inch touchscreen is bright and clear and is angled forward to reduce reflection and glare which was always a problem when a conversion kit was used. The controls themselves are clearly laid out while the touchscreen icons are large and easy to read at a glance. All the original vehicle features are retained such as steering wheel controls.

Pioneer’s acclaimed Navgate software is a joy to use with simple controls but extremely powerful and accurate navigation. The internal, high speed navigation covers 46 countries with more than eleven million points of interest. Powerful algorithms ensure the best route is chosen. Since this system is designed for motorhomes the software allows you to input the vehicle’s weight, height, width and length to make sure you will only be directed to appropriate routes and avoid any restrictions.

Connectivity:

Since almost everyone now uses a smartphone of some sort the Pioneer Evo is equipped with both Apple Car Play and Android Auto ensuring perfect integration with your device. Once connected it allows voice commands to control your system for enhanced safety while driving. Of course it also allows you access to all your stored music and streaming services for the complete entertainment experience.

To further enhance your listening the Pioneer Navgate Evo is equipped with a DAB+ digital radio tuner, full Bluetooth streaming and dual USB inputs. For safety an optional reverse camera is available to assist manoeuvring. There is even a hideaway CD/DVD player available if you still use CDs and of course movies for when stationary.

This unit has all the power and performance you would expect from Pioneer. Therefore we would highly recommend a speaker upgrade to take advantage of this. We have a vast range of speaker systems available; one of the most common popular is the Audison Prima APX165.

This speaker set is ideally sized to replace the front door speakers in the Fiat Ducato and will offer vastly better sound over the standard units. All changes are completely invisible as they fit behind the original trim.

While we are in the doors we would also recommend adding a full treatment of sound deadening. This improves the sound from the speakers and also to reduce road noise. This comprises a layer of sound deadening applied to the metal panel of the door followed by a closed cell foam sheet applied behind the door card. The difference to how quiet the vehicle is has to be experienced to believe it.

Final Touches:

Finally, for those looking for the best possible sound we would add a discreet subwoofer. Usually located under one of the front seats this really lifts the audio performance to home hi-fi standards.

We have the magnificent Pioneer Navgate Evo for Ducato on demonstration in store. If you would like to pop in we are on Sunderland Street in Macclesfield; where we can install any of the above upgrades. If you have any questions or would like to know more about upgrading your motorhome please call us on 01625 432707.

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.

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!

VW Golf 7 Audio Upgrade

Following on from our last blog we have an example of a car audio installation to a VW Golf 7. This is a perfect example of how one of our standard systems is adapted to make sure the owner gets exactly the sound he wants.

As our customer lived a good way from our shop he decided he wanted the whole job done in one rather than splitting it up to spread the cost. Initially, we started to talk about our stage 3 upgrade.

Fortunately, our customer already owned a JL Audio HD600/4. This magnificent amplifier is one of JL’s finest boasting very impressive power figures with incredible dynamic range.

This was an ideal amplifier for a really high-end system; he liked it loud but did not want any distortion when playing his favourite dance music. Since this amp was so good we felt we should recommend an upgrade to the front speakers over the Hertz MPK 165 initially suggested. The owner wanted clarity without colouration and his preference was for a very dynamic high frequency. My recommendation was for the Audison Voce K6 component set.

These speakers are one of my favourites and offer a truly natural sound. The tweeter is larger than some but this helps to give it a remarkably low-frequency capacity meaning a better blend with the mid-range.

We opted to stay with the usual Audison APK165 components for the rear fill. These speakers are a fantastic upgrade to the factory standard at an extremely good price. However, he was happy to upgrade the sub to take advantage of the power available but did not want to lose too much boot space. The obvious choice was the JL Audio 10TW3 in a slim enclosure as this will deliver smooth, powerful bass from an enclosure only 12cm deep.

So to the installation.

Our customer did not want any more boot space taken up so we had to locate the other equipment in the cabin. We knew the amplifier would fit under the passenger seat but this left no room for the Bit10D; that would have to go under the driver’s seat. We also chose to situate the crossovers for the front speakers here as well. This of course added to the complexity of the wiring but by using high-quality speaker cable and double shielded RCA cables there was no chance of any interference or quality loss.

The doors got a complete treatment of Dynamat Extreme and Dynaliner to optimise the acoustics and eliminate any chance of rattles. We built custom collars for the speakers ensuring they were sealed to the panel to maintain moisture protection.

The rear door tweeters are in the door panels but the front ones reside in the A-pillars. We constructed custom mounts for both of these.

Important note.

When removing the VW A-pillars the retaining clips must be replaced with new items as they are an integral part of the airbag safety system and removing the clips compromises their integrity.

The final part of the installation meant mounting the Audison DRC and the location chosen by the customer was the small fold-down tray to the right of the steering wheel.

This location is convenient to use but renders the installation invisible when closed.

The next task was to tune the system. We already knew he liked a bright, dynamic sound so we programmed it for a lot of energy in the higher frequencies without getting harsh. The bass had to be tight and punchy and the TW3 does not disappoint. With so much power available we could keep the gain on the HD600/4 at almost minimum giving the highest dynamic range.

Of course, the speakers will require a week or so of running in before a retune but the owner’s initial reaction was ecstatic. It was all we could do to get him out of the car to register his three-year warrantee!

As mentioned we have standard packages that we can recommend but a great many are customised by us to make sure you get exactly what you want from your new car audio system.
