Hi I'm new and just started driving a '99 Audi A4 2.8 Quattro. I wanted to get my subwoofers and amp installed in the trunk. However, I've been told everytime that trying to do that with an Audi will shutdown everything or something like that. And it's got Bose speakers in there which I've heard was part of the problem too in the fact that it's already got some kind of system in it. I know that I'd get most accurate info from actual Audi drivers here so I'd like to know what you can tell me. Thanks
