Audio Upgrade to BMW Z4 2005

After listening to this car we realised why the customer wanted to upgrade the sound system.  The customer opted for JL Audio speakers which consisted of VR525-CSi front components and VR690TX 6″ x 9″ speakers for the rear.  The subwoofers used were Hertz Energy and these were placed into a custom built enclosure under the rear shelf and then covered with a trim panel so they couldn’t be seen when the boot was open.  The power for all these speakers were from 2 Audison SRx amplifiers, an SRx4 4 channel amp for the speakers and an SR1D mono block amp for the 2 subs.

Really happy with my service and my purchase. Christian and Paul were really honest and polite, and helped me make the right decision in regards to choosing to upgrade my sound system as opposed to replacing my faulty CD player like for like.

When I arrived back home after my short trip from Source to Donny today, I thought a short thank you email was in order. When I first sat behind the wheel and heard what a difference your adjustments had made, I was very pleased. I put Pink Floyds’ “Dark Side Of The Moon” in and set off for home. When I pulled onto my drive, I couldn’t get out of the car for 10 minutes because the CD hadn’t finished. It was stunning ! All the meticulous work you put into my install came together today and exceeded all my expectations. The sound stage is now immense, fills the front of the car and is fully balanced to my seating position. A great many thanks to you and all the team at Source Sounds, I wish you every success in the future.

Dear Chris and Staff I am just writing here to say thank you for the excellent service received from you and all your staff there. People are so quick to complain, but not as quick to congratulate on a job well done. My husband and I are really pleased with the fitting of the sat nav to our Ford Kuga which we feel has been done to a high standard and with excellent attention to detail. The knowledge you and everyone else who works there seems to have is great and gave me great confidence. And the customer services was professional and friendly. Even though the job you did for us was a small one I’m sure, compared to a lot of your other work, I was made to feel that nothing was too much trouble. The time taken to answer my questions and help me out was very much appreciated. I will have no hesitation in recommending you to other people and will certainly be back again. Thank You !
