The best car audio in Sheffield! Paul spent over an hour with me just talking about everything, door speakers, amps, sub woofers & these guys really know their stuff. Chris (who did the work on my car) spent ages making sure I had no rattles at all. I got a top of the range set up within my budget, head unit, amp, sub & door speakers & cannot speak highly enough for these guys, i learned loads & got a system that properly rocks. If you want car audio, go see these guys, even if just for a quick chat, you’ll see what the hype is about. 10/10

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.
