Hey whats going on peeps? Well I have a problem and Im hoping Im not the only one that has had this problem. When ever I drive now it seems with the music down or off all together the back window rattles/scratches. I have a system in the trunk and the trunk has dynomat, which maybe that could be a factor to why I'm having this problem. It seems as if the back window is scratching against the back panels or something Im not to sure. Im wondering how could I fix this. The only thing I do now is keep the music up just enought to drown out the scratches

 

have you checked the panels for being loose. A system will rattle everything to death.
