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.

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.

Your cars security matters

Modern cars are awash with incredible security and comfort systems. Automatic lights, wipers, radar distance detection and auto braking to name only a few. One feature that has become very commonplace is keyless entry and starting. To unlock the car all that is required is to have the keyfob in your pocket as you pull the door handle. The same applies when you push the start button as the car detects the key‘s proximity. Surely this is secure? Maybe not as much as we would like to believe.

 

Obviously the car and the fob are in communication so that they recognise each other but this has thrown up a worrying security breach as the video below demonstrates.

The released footage shows two car thieves (now thankfully caught) stealing a Mercedes in less than 60 seconds. No keys and no damage to the vehicle. They use a ‘relay box’ that can electronically find the key from outside the house and transmit its code to a receiver near the car. This code will unlock the car and allow it to start. What you may not be aware of is that the car will remain running without the fob even when out of range.

So unfortunately all the sophisticated security systems fitted by the car manufacturers are useless. The police are now suggesting we go back to the ‘90s and start fitting ugly steering wheel locks (which are relatively easy to overcome) as a deterrent. There are much better options.

 Ghost immobiliser.

This really is the ultimate protection for modern cars. This extremely high spec. security device can be hidden completely. It radiates no signal and cannot be detected on the vehicle diagnostic port (OBD). It requires the user to enter a code of their choice using existing vehicle buttons before the car can be driven. Since there are no flashing lights or touch key ports there are no cables to follow. Thus making the unit virtually impossible to find and defeat. It acts on the vehicle data network so there are no relay clicks or cut wires to give it away. So whether the thief is armed with a scanner, a relay box or even the genuine key the vehicle will not be able to be driven.

See here for compatible vehicles, if yours is on the list then it is at risk. The development of this unit requires rigorous testing so new vehicles may take a little time to appear.

Installation can only be done by trained, high quality technicians and we are proud to be included as approved installers.

RAC Trackstar tracking unit.

If the car cannot be started then the only option is to physically tow it away and unfortunately this is what is happening. There are even anecdotal reports of brazen thieves turning up with liveried tow trucks in the middle of the day and helping themselves.

While no security device is going to stop this, if there is a good tracking system installed then the action of moving the car at all will alert the tracking station. The movements of the vehicle can then be monitored and the police informed of the location. This usually leads to a speedy and more likely recovery.

We recommend and install the RAC Trackstar tracker. This covertly fitted unit is category 6 insurance approved and is fully automatic. If the vehicle is moved without the key then it immediately reports to base station. They will then contact you to ask if you know if it is moving (for example during service), if it is unauthorised then the vehicle is tracked. If the car were stolen with the key then you would call the emergency number to report a theft and again the vehicle is tracked.

There is an app that allows the user to personally monitor your vehicle’s location.
It even enables you to set a ‘ringfence’ around it to alert you if the vehicle is driven without authorisation.

Recent journeys are also logged providing real information about location and speed.

For many insurance companies these are a required fit for high risk vehicles. However, the peace of mind they offer is priceless even if the installation is not mandatory.

Clifford Concept 650 alarm immobiliser.

We have been fitting the Clifford range of alarms for over 20 years; in all that time they have proved extremely reliable. It is true that they must be installed to a very high standard and that does cost a little more but the protection offered is peerless.

While more modern cars suit the Ghost immobiliser, the Concept 650 is ideal for earlier vehicles and classic cars. As classic vehicle values soar it makes sense to protect them properly and the Clifford is ideal. It is often joked about but the very presence of the distinctive blue LED flashing in the car is enough to deter a potential thief.

As a hard wired system with a high parts count installation is necessarily complex. We go to great lengths to make sure it is discreet and reliable. The basic system offers multi point immobilisation, perimeter protection at all points of entry, internal movement sensor and close external movement warn away sensor. In addition there is a secure PIN coded override button as well as the famous blue LED inside the car. Meanwhile, you get two high range multi-channel remote controls. On top of this, there are further systems that can be installed or enabled. These include anti-hijack, remote start as well as extra sensors such as break glass, tilt or shock. All of these allow us to customise the security to your needs.

Why we do it….

The answer to what we do is easy, it’s in our mission statement;” To provide exceptional audio experiences that exceed expectation”. We achieve that goal by taking the best, most appropriate kit and by drawing on our many years of experience, training and skill we install that equipment to produce an audio system that will deliver exactly what the customer wants and more.

But why do we do it?

Quite simply, passion; a passion for great sound, a passion for music in all its forms and a passion for technology.  As a musician, I truly believe in the power of music’s ability to move, exhilarate and excite. For me, designing and installing systems that can deliver these truly emotional experiences is hugely rewarding. By the same token, it pains me to think of all the terrible audio systems in cars today.

We all know that the BMW and Mini systems are awful but really the audio in VW, Audi and Vauxhall is not much better. Changing these terrible car audio systems can change your life! I mean it, having a great system to listen to will lead to less stress while driving, traffic queues will no longer be a burden as you immerse yourself in your favourite music and you might want to take a little longer getting there so you can listen to a whole album.

How we do it:

Great car audio is complex, much more complex than home audio. In a car, we do not have the luxury of being able to easily move speaker positions or change listening locations. Instead, we have a noisy metal box with lots of hard glass surfaces to reflect sound, fixed speaker and listening positions not to mention electrical and electronic limitations. Unfortunately, a frequent comment I hear is that ‘you can’t get a decent sound in a car’. Well, I would argue that you just haven’t heard one yet. Come and sit in our Land Rover Discovery and listen to what just two speakers, a small sub and amplifier is capable of. I guarantee you’ll be impressed.

But of course, if it were that simple then everyone would do it. The truth is that the final result is going to be determined by a huge number of factors. This is where my experience and training along with my passion to produce the best possible results comes into play. As mentioned previously there are many complications to installing and achieving great car audio, fortunately, there are none that I have not encountered before and certainly none that I cannot overcome. Not only do we strive for the best sound we can but we also take great care to make sure it precisely matches our customer’s needs.

Getting the sound you want may cost a little more than you anticipated but we will only ever advise correctly and ensure that you get the best.

Latest Products from Bose.

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

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

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


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

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

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

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

Soundlink Revolve & Revolve Plus:

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

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

 

 

Bose

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

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

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

 

That concludes the Bose Soundlink line up, all of them are mightily impressive but which one is right for you?

Volkswagen Passat Car Audio Upgrade.

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

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

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

The design process;

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

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

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

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

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

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

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

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

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

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

How did it sound?

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

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

We love to get this right and it gives us great satisfaction to see that big smile from our customers when they hear it for the first time. If you would like to know more about how or have any questions please feel free to give us a call on 01625 432707. Better still call into the shop on Sunderland Street in Macclesfield for a chat.

We hope to hear from you soon.

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!

Looking at Volkswagen systems

I am often asked what system I would recommend for a certain type of car. My answer is usually that it depends on the type of sound and performance you are after. That is certainly true but there are some constants and I think it will be useful to discuss these over a few installments.

For the first one, I will choose the latest VW Golf.

 

The Volkswagen Golf Mk7 is a fabulous car but the audio system leaves a lot to be desired. Even the so called upgrade packs are disappointing and certainly not worth the premium charged. The large screen infotainment system in the dash is certainly smart but does not have a particularly good audio performance while the speakers deliver a lackluster sound at best.

So what are the options?

If you choose to replace the head unit (and we highly recommend it) then the absolute best choice is the Alpine X901D G7.

This exceptionally high-end unit is specifically designed for the VW Golf 7. It is a perfect fit and will support all the existing VW systems such as reverse images, steering wheel controls, and vehicle information displays. The performance leap of this machine over the standard system is amazing and is the perfect base to add an upgrade audio package.

However, you may not wish to change the head unit and we would completely understand this. If your car is leased or on a purchase plan it may be best to not change the look of the vehicle at all.

Fortunately, we have developed several audio packages that can be invisibly added to your car that will massively improve the sound.

The Audison Prima pack:

This specific kit is a true plug and play solution from the masters of OEM integration, Audison. The kit comprises their DSP amplifier with built in EQ presets for the Golf, replacement front door speakers, discreet subwoofer for the boot cavity and all interconnecting cables meaning that nothing needs to be cut or changed. At a little over £1000, this is amazing value for money and sounds far better than the VW dealer upgrade options. Although we would strongly recommend it the sub is optional and if you choose not to have this then the price is even lower!

As soon as you hear this you will notice the massively improved clarity, the sound stage will be higher, wider and more surrounding. The bass will be stronger with a much better punch without being ‘boomy’. Of course, all of this can be removed when you come to change the car and with a little reprogramming can be made to suit whatever car you purchase next making this a much better investment than the dealer options.

At Car and Home Stereo, we have also developed our own upgrade options drawing from the best products from around the world. For convenience, we describe these as Stage 1, 2 and 3 but of course, there are variations to take account of personal tastes and requirements.

Stage 1:

This is full speaker upgrade pack based on the 5 door Golf. While the choice of speakers could change the acoustic improvement products do not. These are as important as the speakers themselves in maximising the performance of the upgrade.

The full kit comprises Hertz MPK 165 front component speakers, Audison Prima APK rear component speakers, 4 sheets of Dynamat Extreme sound deadening, 2 sets of F.A.S.T. acoustic foam sealing rings and 2 sets of speaker mounting collars.

The cost of the stage 1 upgrade is only £650 with an installed price of £900. Even on the standard VW head unit this sounds amazing with improved clarity and bass performance. The performance detail is also improved thanks to the far more sensitive speakers and the acoustic treatment in the doors.

Stage 2:

This is a stand-alone sub and amplifier package. As you can imagine there are many to choose from but there are two that we have found to be highly suited to the Golf as they are powerful but take up a relatively small space in the boot.

Stage 2a is the Audison APBX 8R slim sub enclosure and the small but powerful Hertz DPower 1 amplifier.

This offers 600W output and will tuck into one side of the boot taking up almost no space at all and at only £479 for the two it represents great value for money.

Stage 2b is the same amplifier but married to the fantastic JL Audio 10TW3 sub in a slim enclosure. This sub is exquisitely musical, a real hi-fi experience and this package adds up to £650.

This amazing, compact sub can also handle a lot more power if you are a real bass nut!

Stage 3:

This brings everything from before and adds amplification and processing to the entire system. There are again two recommended packages here.

Stage 3a uses the Audison AP Bit amplifier. This incredible amp with built in processor is tiny and powerful, quite capable of driving the entire car system. The on board processor allows for perfect tuning of the sound stage to suit anybody’s taste. The phase and time alignment controls mean the sound can be focused to wherever it is needed making for a wide and spacious soundstage. These amplifiers start at only £600 so represent tremendous value for money.

Stage 3b is a combination of the JL Audio FiX 82 processor with the JL Audio XD400/4v2 amplifier. The processor is specifically designed to automatically compensate for original head unit anomalies. It will take out any spurious EQ that has been added by the factory radio as well as eliminating any unwanted phase changes. It also allows for personal tuning via PC to really dial a system in. Once the processor has cleaned the signal up the XD 400/4 amplifier delivers the power. This amplifier has become one of my firm favourites offering tremendous, clean power from a very compact chassis.

This package is slightly more expensive at £750 but does offer a higher level of performance.

As I mentioned earlier these packages are extremely flexible to suit individual requirements but I can heartily recommend any one of the above. We have installed many of these systems and know that they perform brilliantly.
