my hatch cover vibrates alot win my subs hit and my sound system hits pretty clean without it on so it there a way to fix it from vibrating, do other people have the same problem?

 

never heard mine do it, take the cover off and get 5% limo tint on the back window ..

just make sure all the back screws on the hatch are tight, and your clipping it into the metal portion of it. If that dont work then I'm out of ideas.
