I'm no sound expert but from what I have heard is that Bose are pretty good sound systems but I'm dissapointed with it on my 147. First off you have to crank the sucker to 50 just to get proper audio level. The speaker on the drivers side is softer than the other even when playing with the balance. Also in the boot there is a Bose emblem on the carpet, is there a amp or something that may not be working ? Almost any over the counter stereo will give better sound than what I have Are you guys happy with yours ?
