I had the Bose system in mine and it irritated the life out of me.
Fitted Andy's sub kit and sound deadening and it was a huge improvement, almost good, definitely acceptable.
I made the mistake of hearing Andy's front door system. From there on it was only a question of when, not if, I was going to fit it.
I went for the center as well, 7 sheets of silent coat to each door and Bit ten processor.
I just don't want to get out of the car now. It really has transformed the car for me.
Can't thank Andy enough for getting a solution to the original crap sound.
If anyone needs any phone support when fitting their own, drop me a pm and I'll reply with my number. Having done the whole process myself, it seemed a bit daunting to start but now I would have no hesitation doing again.
Satan.
