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.

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.

Car audio upgrades, sometimes simple is best.

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

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

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

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

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

So what should we choose?

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

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

Choices, choices…what amplifier to choose?

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

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

But what subwoofer should we fit?

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

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

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

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

If you would like to know more about how we can improve the audio in your car then please give us a call on 01625 432707 or better still call into the shop on Sunderland Street in Macclesfield for a chat and a demonstration.

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.

porsche boxster 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.

Hertz D Power 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!

Bose SoundTouch – Bringing Music Everywhere

It is true to say that music has never been more accessible. Anything you might want to listen to is only a click away. You can choose to purchase it via a download site but more and more of us choose to subscribe to a streaming service such as Spotify, Deezer or Apple Music.  For a small monthly fee the whole world of music is at our fingertips like a vast lending library and as a true on demand service, we no longer need huge collections of CDs cluttering up the place.

All well and good you say but what are we supposed to play all this music on; our phone’s headphones, computer or tablet?

That’s not going to sound very good, is it?

No, we want a high-quality hi-fi system and that surely is why we need our CD players? Well maybe, but there is a fantastic alternative from Bose; the SoundTouch system.

The Bose SoundTouch wireless music players are easy to use, sound amazing and look superb. They are feature packed and there is a solution for any situation where high-quality music is required.

So how does it work?

The Bose SoundTouch system is designed to connect to your home wi-fi network. This allows it to connect to any music libraries you may have on a computer as well as being able to connect to your broadband link to play internet radio from around the world. On top of this, the SoundTouch system is equipped with Bluetooth connectivity; so you can connect any portable device, phone or tablet and stream your music. If you do subscribe to a music streaming service such as Spotify you can play this directly from the Bose control app on your device. It doesn’t stop there either because this is a fully networked system you can wirelessly connect multiple devices; these can be independent in each room or grouped together to play the same music throughout the house.

The simple control app can be downloaded to as many devices as you want which means you should always have a controller nearby but just to add another level of simplicity all the stand alone SoundTouch players have volume, source and radio pre-set buttons on the top to allow quick operation.

Let’s look at the SoundTouch family.

SoundTouch 10,20 and 30.

These compact and versatile units just need a mains power supply and your wi-fi network to play all your favourite music. The smallest unit, the Soundtouch 10 is ideally suited to smaller rooms such as the bedroom or study while the SoundTouch 20 and 30 are completely at home in larger spaces. The SoundTouch 30 with its integrated woofer produces a magnificent sound that will fill any space with rich, powerful music. All are available in black or white to suit any décor.

SoundTouch 300 and optional Acoustimass sub and surround speakers.

The SoundTouch 300 is a soundbar of course but unlike any other. Of course, as part of the SoundTouch family, it has all the convenience and power of the network but adds connectivity for your TV. It carries the proprietary Bose AdaptiQ system to learn the layout of your room and seating positions; ensuring you always get the best possible sound. Even on its own, this bar can generate a very impressive surround effect but if you add the optional sub and wireless surround speakers you will have a true 5.1 surround system that will delight. Again, very easy to use and even the remote control can be programmed to emulate any other meaning your Bose remote can control all your other devices such as Sky, Virgin, and TV.

SoundTouch Lifestyle 650 and 600.

If you want the absolute best for your TV and living room then look no further than the Bose Lifestyle 650. This powerful and elegant system with its virtually invisible speakers is beyond compare. The feature list is almost endless but what really matters is the sound. This surround system offers a level of audio immersion that is simply incredible. From the deepest rumbles to the lightest detail this system plays it all with precision. Since it also contains the full Soundtouch system for your music the Lifestyle 650 and 600 are truly total entertainment systems.

SoundTouch SA5 amplifier.

You may have a great pair of speakers already or may want ceiling speakers to keep it neat. You may want speakers outside or in other wet places where it would be impossible to take a mains powered device. In these cases the Bose SoundTouch SA5 amplifier is perfect. This can be installed inside the house and speaker wires run to wherever they are needed. Full control is via the control app and there is an AUX input for connection of external devices (e.g. TV).

SoundTouch wireless link.

This unassuming little unit is brilliant. It has all the power of the SoundTouch network and Bluetooth connectivity. That means you can stream your music, access internet radio or Bluetooth link your mobile device. This can then be connected to any hi-fi unit, Bose or otherwise; giving you the full range of SoundTouch features on any entertainment system with an external input.

Range Rover Recovery

The Range Rover Vogue or L322 as it’s known. A British classic with world beating all terrain capability that will take you anywhere in leather trimmed luxury.

Now anyone who has owned one of these will know that there are a few niggles with this vehicle and one of the common problems is the audio. One day the stereo will not make a sound or the screen will just show the Land Rover logo while the red light just flashes on the volume control. This usually means the main amplifier has failed in the rear of the car. It could also be a failure of one of the other components in the audio chain but the amplifier is most common.

The cost of a replacement from Land Rover will leave you shocked, an eBay one will set you back a few hundred pounds with no guarantee and you may be no further forward if that is not the problem. Even if it is you will only have the same performance as before. Wouldn’t it be nice to properly improve the system while you have the chance?

This was the situation our customer recently had and after a short discussion and a budget decided upon we set to work overhauling the whole system.

The vehicle owner had specified the Pioneer Avic F88DAB head unit.

The rest was up to us.

The first job was to strip out all the unnecessary kit in the rear of the vehicle and from the dash.

Not for the feint hearted but reasonably straight forward when you know where all the hidden screws are! We will, of course, be rewiring the system so there will inevitably be many unused plugs on the original looms. These cannot be left to rattle around the back of the dash so we make sure that each unused end is padded and secured. There is also a reasonable amount of modification required behind the dash to allow the double din unit to fit. We have done quite a few of these and are used to it but again great care is needed.

Once the car was stripped it was time to install the new cabling. We had already decided on the system components and so we produced a custom loom for this. The Range Rover is a big vehicle and it still surprises me how long these looms need to be. All the service accessories need to be installed for the head unit; such as the Bluetooth microphone, dual USB ports, DAB and GPS aerials. We usually fit one USB to the centre arm rest bin and one to the glove box while the other items are discreetly fitted for optimum performance. I also replaced the original rear view camera that had failed. Car & Home Stereo can install a new camera into the original housing keeping the OE look.

Now the head unit can be installed and the dash rebuilt.

I think you will agree that this now looks far better!

The next task was to upgrade all the speakers and we decided on Audison all round. These Italian speakers are superb and so much better than the fitted Harmon Kardon units. A component set was installed in each door.

Now for the fun part!

Knowing the tastes of the customer we knew that he would want plenty of power. Space is a little limited so we needed an amplifier with high performance but compact size and the perfect candidate was the fabulous JL Audio RD 400/4.

This compact power house is a gem of an amplifier boasting 100W per channel. The sound quality from these is amazing. It shares a lot of the design features of the award winning JL Audio XD amplifiers but at a lower price.

This amplifier will fit perfectly in the metal rack assembly in the boot cavity. It is hidden but easily available for any adjustments required.

The results are astonishing. The improvement over the factory system is huge; the detail at the front is crisp and the bass performance feels solid with no distortion. I would recommend this system to anyone with a failing factory audio.

If you would like to know more about how we can improve the system in your Range Rover (or any vehicle) please give me a call; on 01625 432707 or better still call into the shop on Sunderland Street in Macclesfield.

Awesome Audi

We have recently completed the audio system for this magnificent Audi S3. If you have read the previous instalment you will already be familiar with the car but it has developed considerably since then! This piece is a perfect example of how we work with our customers to achieve their audio dreams.

This has been a developing project in the quest for the best performance. What started as a simple bass upgrade has turned into a monster!

First things first:

When the car left the factory it was equipped with the B&O audio system and was quite frankly appalling. The front end detail was reasonable but the bass response was dire. The ‘sub’ that was fitted in the boot was a flimsy plastic chamber with a low quality, 6-inch paper and plastic speaker. Any attempt to push the bass resulted in a feeble burp, it had to go.

During the discussion with the owner it quickly became apparent that he was a true music addict and a simple upgrade was not going to be on the cards, he also admitted to being a JL Audio fan which we definitely approve of. We applied the simple motto that you can never have too much, only too little and recommended a JL Audio 12w6 subwoofer and an XD 1000/1 amplifier to drive it. Now we already knew that the signal from the factory amplifier was poor so we also recommended a JL Audio FiX processor to clean the response up.

The 12w6 sub is one of my all-time favourites and the results were very impressive but it wasn’t long before the bug bit again and our customer returned for more. Another 12w6 and XD1000/1 later the bass performance was doubled. Brilliant, but now the front end was starting to sound really bad in comparison, so a speaker upgrade was discussed.

Copious amounts of Dynamat inside and out kept the noise and vibration down while a set of JL Audio C5 650 components went in the front. This was all powered by a JL XD 400/4 in active mode while the awesome TwK processor allowed me to carefully tune the system.

 

The sound was amazing and that could have been where it ended, or so we thought.

Next Steps:

The owner of the car felt that there was a slight gap in the low mid frequency performance, and knew that there was room for an extra speaker in the middle of the door. That speaker can only be a 4-inch shallow unit so we knew it could not add the desired low mid. However the main door speaker location can accommodate an 8-inch driver and it just so happens that JL Audio produces a fantastic eight inch, free air mid bass unit, the ZR 800 CW.

This is a big driver but with a carefully designed spacer collar, it just fitted into the lower speaker position.

So what should we use for the high-mid and tweeter? Unfortunately JL Audio does not currently have a slim 4-inch but there is one company that has the perfect solution. The Focal 100KRS is a magnificent small speaker we use it a lot in Land Rover Defenders and know its potential so this was what we recommended. Again we produced mounting collars and the fit was perfect.

Of course, this extra speaker needed driving and there was really only one option for us and that was the JL Audio XD 800/8.

This allowed us to drive the tweeters and 4-inch mids at 100W while delivering a full 200W into each ZR mid-bass driver. Another cool feature is that the 800/8 shares the same chassis with the 1000/1 so now we had three identical looking amps in the boot!

What a sound we had now. The low mid gap was gone and the punch was quite something to experience. Thanks to the TwK processor the sound stage was crystal clear and right in front of the driver.

Was this finally the end? Oh no!

One thing still had to be addressed, the boot build. “Oh and while you do that since we can’t get a third sub in the boot can we squeeze any more performance from the existing two?” Challenge duly set we opted to refit the subs into slot ported enclosures giving us a realistic increase of up to 9dB from the same amplifiers. The owner wanted blue Alcantara to match the car with a raised JL motif on the box. Well, how could we refuse!

There’s definitely no room for golf clubs but that hardly matters when you hear this. There is, of course, a bass control at the front of the car and when wound up to full this system leaves you breathless.

This install has turned into one of my favourites and complements this gorgeous car perfectly. Look out for it at a show near you and you might just get to hear it.
