Re: A4 Speaker Size (Mario Maverick)
Well, in my mother's 2000 A4 1.8T without the Bose package, the speakers are really 4.5" (or whatever the standard 4" size is) and I had to buy MB Quart speaker adapters to be able to get my Boston ProSeries 5.5s to fit. I had to remove the door to do this. I assume the 6.??" size refers to the 2002s, but I also think that even if Audi did use 6.75" speakers, 6.5s shouldn't require much or any "adapting" at all to fit.
