Harman Kardon rear trunk sub woofer rattle help in 2003 E46 M3 Convertible
I have a Harman Kardon audio system in my 2003 M3 convertible. My rear sub woofer (the one in the trunk between the rear seats) makes annoying rattles. I removed the rear seats to save weight on the car (about 40 lbs! less) so this may be part of the problem, but any recommendations on how to reduce the rattling? I covered where the seats used to be with black automotive carpeting. Maybe padding with dynamax between the carpet and the bare back (seat back rest) of the car would do the trick?
