When I refer to the "wall," I am speaking of the piece that divides the trunk from the cockpit, where the rear speakers are mounted.

I've been noticing that when there is a bass note in the music, there is a almost "flutter-like" sound that comes from that area. I'm not sure what a blown speaker sounds like, but this is what I kind of suspect. Bass is 7, and it is a really cheap sound, like a cheap sound system "Upgrade." It bothers me because I am usually ALWAYS listening to music while driving. It happens at any volume over +10.


So, does anybody have any idea what i could be? If it's something that needs to be fixed, I'd like for that to be done while it's still under warranty.

Thanks.
