rear deck rattle

[nat3d]

so when my sub hits it shakes my rear deck and back glass and makes it rattle pretty bad. my rear deck is dynamated so im assuming the cover is vibrating off the back glass (like where my third break light is) anyone have an idea on how to fix that?

Did you dynamat both sides of the rear deck? Try using a little block of styrofoam and make it fit between the third brake light and the windshield
