Hey guys, a couple of weeks ago I took my car to my audio shop I usually go to to get my amp moved off of my sub box. When I got my car back, I was driving away listening to some music. I have two 12 kicker cvr's so it hits pretty hard. I like my music. But I noticed an awful rattling sound coming from the back seat that wasnt there before. When it starts to rattle if I push up on the headliner in the back, it stops... my question is how do I fix it? or what is the problem? Do I need to take the headliner out to see what it is? Thanks guys.

 

....anyone?

 

i think you should try to put some foam there and see if that helps
