Awesome Audi

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

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

First things first:

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

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

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

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


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

Next Steps:

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

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

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

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

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

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

Was this finally the end? Oh no!

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

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

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