PLASTIC TRIM (and its vibrations)
 

Ive decided that Im going to add some foam or something of the sort to the back of the back rear plastic trim pieces. Do they just pop off and what is the best way to go about taking them off? Im doing this mostly beacuse of the recent addition of subs and if anyone has any better ideas PLEASE SUGGEST THEM:D.

...I know about dynamat but its not THAT bad. I can lightly pull them with my fingers and it will stop.
