I have 2 12" subwoofers in my truck. they sound good only the back wall of my truck's cabin rattles and it sounds crappy. how can i make it stop rattling?
Get rid of the subwoofers. If they annoy you, think about how much they annoy everybody else. Do you have any idea how irritating it is sitting in traffic next to some deaf brain dead douche who thinks he has to prove something with his giant speakers?
