Tim on Driving Sounds Magazine

As the UK’s only specialist car audio magazine, Driving Sounds aims to bring this niche industry to the attention of a wider public by promoting good sound in cars.

Good car audio is not only about equipment but also about the way it is installed which makes the industry unique. In most cases a system is sold complete with installation expertise, which is required to ensure that a vehicle’s standard functions and systems are not adversely affected.

Driving Sounds Magazine presents readers with reviews of vehicles that drivers have had audio installs fitted to. There are product reviews, installer features and also simplified explanations of what bits of a technical specification and features list are important to the final sound and which are simply marketing noise.

Simplicity Wins

At Car and Home Stereo we regularly install very high performance, in-car audio systems. It is intensely satisfying to build these systems as the musical performance they deliver is breathtaking. These systems do of course come with quite a high price tag so what can we do if the budget is a little more modest?

Let’s meet ‘James’. He’s 22 and just bought his first new car, a Ford Fiesta ST.

He loves music and thinks the standard sound system is OK especially since the car is equipped with Bluetooth so he can stream from his phone. After owning it for a while he starts to think about improving the sound but after lease payments and insurance he’s not got a lot to play with.

The first thing we will ask when he calls in to the shop is what type of music he listens to and what sort of sound he likes. The next step is to sit in his car and listen to the sound, often we will find the tone controls have been set to max bass and treble in an attempt to get a better sound. This usually just has the effect of making the sound muddy as the speakers cannot cope.

Now we know he would like a better bass performance for his music and more clarity from the main speakers. We need to add a subwoofer and better speakers to achieve a complete improvement. James has a limited budget and wants to get the best performance boost for the money.

We have a wide range of products available to suit all requirements but in this case an ideal solution would be the Rainbow Intellisub 8 and a set of JL Audio TR650 CSI components for the front doors. Total cost installed of £500. This very simple system would transform the performance of the audio and give years of pleasure.

But what if the budget will not stretch to £500, should we find cheaper products? The answer is always no. It is never worth compromising performance for price. There are cheaper products out there but they are always inferior and will not stand the test of time. The best option is to split the installation and have one part now and the next when funds allow. So which part first?

Simple, the sub. By adding the extra bass system there are two immediate benefits. First and most obvious is the bass improvement with greater depth and punch. The second improvement is more subtle, as there is no need for the main speakers to produce bass they start to sound a lot better. Certainly good enough while you save for the speakers!

I give this advice on an almost daily basis and it’s worth has been proved time and again with customers who have simple audio systems that far exceed their expectations. We have an in store demonstration stand that shows this off beautifully so please feel free to call into our shop on Sunderland Street in Macclesfield and we can start your journey to a better sound.

Demonstration of Distortion

An interesting situation occurred at Car and Home Stereo recently that I would like to share. It highlighted a phenomenon that is quite counter intuitive and led to some interesting discussions.

We have a demonstration Land Rover Discovery that has a simple, high quality audio system installed that is tuned to perfectly suit the interior acoustics. We always encourage our customers to sit in and experience it as it shows what can really be done with car audio. The amplifier that powers the system is the magnificent Audison 5.1K which develops a true 1650 Watts.

There is one pair of component Hertz Mille Legend speakers in the front doors and a Hertz Mille subwoofer in the rear.

A customer recently auditioned the system and we spent a good hour playing different types of music with a view to producing something similar in his car. He was completely blown away with the sound, couldn’t believe the clarity and how the sub blended perfectly with the whole system. And then he said ‘I love it, but it’s not very loud is it?’. In fact he reckoned his standard Ford system was louder!

Now I know just how loud our system is and the odd thing is that the cleaner the sound the less we perceive volume. Since we had some time I decided to run a little proof experiment with my customer’s car.

As part of our equipment set we have an industry standard spectrum analyser which is also equipped with an SPL meter. It was a simple task to set this up in the Discovery first and then the Ford to compare. As expected our Discovery hit 126dB easily, the Ford however struggled to hit 110dB. In real world terms this equates to a perceived doubling of power (a true doubling is 3dB but we don’t really hear it that way). The next test was the distortion level. By plugging an oscilloscope into the amplifier output we can measure the clipping levels. Unsurprisingly the Discovery registered less than 5 percent distortion at full volume as this was how it was set up. However the Ford reached 5 percent at a little over half volume and climbed to over 25 percent.

There is no arguing with the figures so what is going on? Simply that the higher  distortion levels were being registered as unpleasantly loud and our brains are trying to get us to turn it down! Distortion is the quickest way to destroy a speaker or indeed your hearing.

At Car an Home Stereo we value our customers and hope to be providing high quality audio systems for many years. A distorted sound system will very quickly do serious harm to our hearing and that is why we only choose the best equipment and like to carefully set these up to give the best possible sound. Brands such as JL Audio, Audison, Hertz and Dynamat may not be the cheapest but certainly are amongst the best. The fact that when installed correctly they can deliver an amazing sound makes them excellent value for money.

As to my customer with the Ford, he now has a fabulous system based around a JL Audio amp and speakers with a Rainbow active sub. He loves to play it loud and I know it will give him years of pleasure without doing any harm.
