My little "how to" video on solving the majority of rear end rattle from a subwoofer. I originally had plans just to get some dynamat, but it sounded like there was just to much noise. Not just things vibrating. I took the panel off and saw metal on metal contact and found a way to solve it. I made the video to show what i found and the solution i used to get rid of the rattle. I also show a solution for the bumper rattle.
