I think the rear speaker behind the backseats blew, it sounds like something is vibrating around in it...
if it blew how could i fix it or replace it? thank you

 

same with mine, i heard that we have to get to the speaker and glue the dust cap back on because most likely thats the problem. can you hear it vibrate louder when the bass is higher? thats what mine is doing so i figured it must be the dust cap.

 

Yep, bad job from audi. theres a diy on fixing it, but its just common sense...just glue it back with some high-strength adhesive and problem solved,.

 

Hey hey now, Bose design, not audi.

 

Or you could replace it with something doesn't suck. Also, your fade should be mostly to the front, anyway.
