New car audio products from Pioneer, JL Audio & more

Recently, newly released products in car audio have been really exciting. In fact, it never ceases to amaze me how innovative our industry is and how we manage to stay ten steps ahead of the car manufacturers. In this blog, we will look at some of our favourite products that are new this autumn/winter.

Pioneer multimedia units:

First up is the new range of multimedia navigation units from Pioneer.

As you would expect from Pioneer, this new range boasts the usual array of high-end features. This includes stunning screen and graphics, superb navigation, DVD/CD, Bluetooth, dual USB, DAB and FM/AM radio. However, on top of this, they now feature the very first fully wireless Apple Car Play.

Equipped with a wifi chip, the new AVIC range from Pioneer means that gone are the days of fumbling for your frayed and unreliable connector. Your iPhone will automatically sync with your in-car entertainment system when you get in. Music can now be streamed via wifi for superior sound compared to Bluetooth. Your iPhone stays safely in your pocket while Eyes Free Siri can control all aspects of the Car Play features. Driving just got a great deal safer! These systems can start from as little as £750 fitted, an absolutely amazing price considering the sophistication of these units.

Alpine in-car entertainment:

Another absolutely stunning new arrival is from Alpine electronics, the iLX F903D Halo 9.

 

Alpines reputation for amazing vehicle specific head units is rapidly growing. Along with this, they have been the leaders of in-car entertainment for decades.

The Halo 9 is something really special. This has to be seen to be appreciated as no picture can do justice to the simply gorgeous 9-inch touchscreen. The 903 is equipped with Bluetooth, Apple Car Play, Android Auto, DAB radio, FM/AM tuner, HDMI input and a host of AV inputs for parking cameras and accessories.

These units have been especially popular with VW Transporter owners and we have a bespoke installation kit for the T5/T6 which allows retention of all steering wheel controls as well as parking visualisations. Once connected to your smartphone you can use a selection of navigation apps including; Waze, Google maps and Apple maps, all your stored music is available as well as various streaming services such as Spotify and Amazon Music. This device will read out texts, allow you to dictate replies, use WhatsApp and of course make and receive hands-free calls. All this is displayed on the huge, clear display and the fully glass capacitive screen is a joy to use.

This unit would grace any car but can even be fitted where previously a conventional double Din unit was prohibited because of the dash design. We have them in stock and ready to fit.

JL Audio Amplifier:

Moving away from head units we are now installing the new JL Audio VXi range of amplifiers.

These are extremely compact with spectacular power output and are everything you would expect from JL Audio. The icing on the cake is that the VXi amplifiers also contain a full TwK Digital Signal Processor.

Coupled with the powerful TuN software these amplifiers offer unmatched precision and power. JL Audio is relatively late to the whole DSP movement. However, this is because they have been developing a product designed to be the best and this shows in the huge suite of controls and level of sophistication available. In no way is this product for the enthusiastic amateur but in the right hands, it allows absolute control and the ability to fine-tune a car audio system to perfection.

Audison Speaker:

One of the leaders in car speaker technology has to be Audison, their Voce range is one of my all-time favourites and I use their Prima range as my ‘go to’ speaker if I am upgrading a standard audio system. Their latest offerings are sure to be massively popular as they are custom sets for BMW and Mini.

We all know the BMW sound system is awful and there are plenty of custom options to supposedly ‘upgrade’ the sound, unfortunately, some of them are little better than the original. So I am very pleased to see the Prima BMW kit from Audison.

Like other manufacturers, these are designed as a perfect fit to the BMW and Mini but these are engineered to a whole new level. Audison has created a main driver with more excursion for the best possible mid-bass performance while the tweeter has a beautifully smooth response to blend seamlessly with the mid. Yes, they cost a little more than some but the performance benefits are more than worth it.

We at Car and Home Stereo are always looking for the finest products; so that we can supply the best possible experience at any budget. After all, whether you spend £100 or £10,000 you want the best value for money and that is what we strive to provide; the best products with the best service.

If you would like to know more about our products and services for car and home audio please call us on 01625 432707 or 07971 928881, email sales@carhomestereo.co.uk or pop in for a chat and a coffee at our shop on Sunderland Street, Macclesfield. We hope to see you soon.

 

 

Bentley and Mercedes audio upgrades

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

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

Bentley Upgrade:

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

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

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

 

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

Mercedes Upgrade:

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

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

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

 

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

 

Audi TT Audio Upgrade

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

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

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

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

Audi TT audio upgrade

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

Speakers:

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

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

What else?

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

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

 

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

Amplifier:

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

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

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

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

Is it all worth it?

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

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

Amplifiers: The heart of the car audio system.

In its basic form an amplifier has one job, to take a small signal and make it bigger.

amplifier

This would be so easy if music looked like the above sin wave but of course music is much more complex.

Music is a complex mix of multiple frequencies with varying levels and shapes. Sin waves, square waves, saw tooth waves all layered to create sophisticated patterns of vibrations in the air. Astonishingly our ears can pick up these complex and subtle vibrations and our brains can interpret these signals at a very precise level and let us experience music. Consider listening to a large orchestra. Even when all the instruments are playing it is possible for our ears to detect just one small part rather than a wall of noise. Composers know this and carefully layer instruments to create symphonic masterpieces.

How a speaker can reproduce this is for another discussion but let us consider the amplifier.

The signal coming from the CD player should contain an accurate version of the music at a very low level. I say ‘should’ because a lot of standard fit head units actually do not have a clean signal and this has to be dealt with before it gets to the amplifier but again that is for another discussion. So let’s assume there is an accurate signal leaving the CD player which contains all the subtle nuances of the music.

What happens inside that big box?

As I said earlier, the small signals from the CD player have to be made larger so the speakers can play them but as I also mentioned these signals are extremely complex. Recreating these complex signals requires some very sophisticated circuitry but above all very high quality electronic components.

So what is it you get when buying a better amplifier?

I like to use the analogy of standard, high, and ultra high definition TV. If you have experienced all three types then you know the difference. Standard definition is OK and is, for most purposes good enough. However high definition is sharper and clearer so no fuzziness around the edges making it easier to watch. Ultra high definition takes it to another level and quite honestly it’s pretty much like looking through a window with vibrant and subtle colours, crystal clear images with no flicker or artefacts. You could describe it as just like the real thing and this makes it much less fatiguing to watch as your brain does not have to compensate for the poor image.

Music is exactly the same, the more accurately it is reproduced the less your brain has to compensate for distortion or missing information. This compensation is what causes listening fatigue and can lead to headaches and the desire to turn the system off!

A better amplifier will be able to reproduce every last nuance and detail of the music and you can quickly tell the difference when you hear it. You will notice things in the music that you have never heard before; instruments will be clear and well defined without any muddiness when there is a lot of information playing. Vocals will be lifelike even allowing you to hear the space they were recorded in exactly as the artist intended. This is what a really good amplifier can do for you and why it is always worth spending more to get a better sound.

Someone once told me a good way to describe better and better sound was to think of the artist playing behind layers of curtains, each time you improve the system you remove a curtain until eventually you are standing in front of them.

So what does it take to get right to the front?

The Audison Thesis Venti amplifier. Over £8000 of sonic perfection for two channels. If you want the best then here it is.

If you would like to know more about how we can improve the sound in your car please call us on 01625 432707 or pop into our shop on Sunderland Street in Macclesfield.

 

Digital Signal Processing

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

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

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

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

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

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

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

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

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

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

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

Improving the BMW audio

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

Standard BMW speaker.

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

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

Stage 1; upgrading the speakers.

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

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

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

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

Stage 2; amplification.

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

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

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

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

Stage 3; adding a sub-woofer.

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

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

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

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

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

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

What to consider when buying your first car:

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

Finance:

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

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

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

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

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

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

Insurance:

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

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

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

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

How to get the price down:

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

Buying new or second hand:

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

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

Gap Insurance:

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

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

Used Cars:

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

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

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

Sub-woofer: bass in not much space.

There is no getting away from the fact that every good car audio system needs a sub-woofer for a full range sound. By their very nature a sub-woofer needs to be large to play the frequencies required and it will also need to be in some kind of enclosure. So we have a large speaker in a fair size box, where is it going to go? Well that’s usually the boot. While the show car installations look great they can be a little impractical.

Just about room for a packed lunch in this one we made but on the plus side it did sound amazing.

What we often do is try to take up as little space as possible.

That could be by using one of the new breed of sub-woofers that are designed to operate in very small enclosures like the Audison Prima series.

These fabulous subs are completely at home in small boxes and are extremely slim as well. That means that even the 10 inch driver can virtually disappear into the boot leaving the lion’s share of the space free.

Sometimes however placing an enclosure in the boot is just not practical.

There might be a need for the whole of the load space, there might be wet items to carry such as bikes and prams or it might simply just look out of place. For those occasions we can build bespoke enclosures using existing voids so as to impose on the load space to the smallest degree.

That usually means fabricating with a composite of fibre glass and wood. We can mould these to be a perfect fit to the vehicle and when done right can sound amazing. The steps to producing one of these are always the same.

First we need to determine that there will be enough space.

All sub-woofers work best in a specific volume of air and it is essential that we do not restrict the performance by under sizing the box. Once we know that there is enough space we need to create a mould of the vehicle trim.

When I am happy that we have enough space the appropriate piece of vehicle trim is carefully removed and masked; before the first layers of fibre glass are applied. Once set this can be trimmed to the correct dimensions and the MDF front applied. Further layers of fibre glass are applied to seal the face to the enclosure. This can then be trimmed in an appropriate finish.

As can be seen, I like to line the inside of the enclosure with Dynamat sound deadening. This dramatically reduces any possibility of resonance and increases structural integrity.

By now the vehicle trim panels are all replaced and the enclosure can be securely mounted to the car. It is vital that the mounting is solid as although the enclosure is relatively light the subwoofer is not. This extra weight must be mounted in such a way that trim cannot rattle and of course the whole thing must be secure against movement during driving.

The final result is a discreet installation that uses a minimum of useful space.

I recently produced this enclosure for a Land Rover Freelander. As you can see it blends seamlessly with the vehicle and takes up no useful space. It contains the unbelievable Hertz ML2000.3 subwoofer. This 8 inch woofer has enough punch to fill the large Freelander with tight and deep bass and has a level of sensitivity that can play the lightest of bass notes.

If you would like to know more about our bespoke building service please call us on 01625 432707 or better still call into the shop on Sunderland Street in 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.

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!
