Okay i seem to have a bose sound system in my 1999 audi s3. Now everytime i play music and there is some bass it goes all distorted and pops. Basical the sub speaker is blown and i need a new one. So i went into my loft and found from my old cars a kenwood dvd headunit with amplifyer, small sub with built in amp and some parcel shelf speakers. So i decided that i was going to wire this all in to my car. Went down to Halfords this morning to get a basic wireing kit as i have lost parts of mine and got speaking to one of the helpers there. He told me that i would not be able to wire onto the door speaks as they are fiber optic and that if i mess with the sound system it can put my car into safe mode. So the question is:
Is this true?
What have other people done to enhance their bose sound system?
