BMW M3 CSL gets a Stealth Install

This being the CSL version, the customer also used the car for track days aswell as normal driving so didn’t want to put too much additional equipment into the vehicle.  We suggested a product that was made specifically for this model of BMW, a pair of JL Audio 8″ subwoofer enclosures that replaced the original rear speakers and mounted to the rear shelf.  This gave him subbase in the car without adding a huge box into the boot compartment.

After a few listens we decided on a set of Focal 165K2P front 6.50″ component speakers and a Genesis 4 channel Series III amplifier to power the system.  As the products were of real high quality the customer also used cabling of the same quality, 2x Chord Cobra RCA cables and Chord Carnival Silver Screen speaker cable to get the best out of the system.  The amplifier was fitted underneath the boot carpet so as not to take up any valuable space the customer may need to use.

Absolutely brilliant, outstanding service from advice on which alarm to have, very professional install and great introduction to the system when it’s fitted. I’d recommend these to anyone. Well done!

Just wanted to say a massive thankyou to you guys at Source, especially Chris and Paul who over the past few weeks have impressed me no end. I went to them with a typically sub-standard BMW sound system, not really knowing how it should be improved and had a really friendly informal chat with Chris about the best route to take. What has impressed me most is that never at any point are the people here pushy – they really listen to your requirements and budget and make honest suggestions and give a number of options. Chris and Paul both spoke in some detail about what the issues were and how the problems could be addressed and I felt I was in safe, honest hands throughout the upgrade process. A whole new set of 3 way speaker set up and a new amp later the car sounds crystal clear like never before. Not wanting to change the head unit, the guys had solutions as to how to keep the car looking as factory as possible, and even asked me back in so they could check how the system has bedded in. Old components are carefully removed, allowing you to have them replaced should the car ever be sold. Their installation couldn’t be faulted and their customer service is genuinely excellent – polite, highly knowledgeable and above all honest, with their customer’s best interests at heart. I have no reservations in fully recommending them and have no doubt I will be back in future. Thanks again gents !! Jason
