Have any of you used Dynamat Xtreme on your car? If so, where did you put it, and did it improve quietness inside the car?

i fully did the trunk and the rear insides of the quarter panels, it didnt do much except make my bass sound cleaner, still get a ton of squeaking from all the parts in the car. everything is too loose, the side pockets and the things in the trunk next to the cargo cover.

 

has anybody done the doors? i'm curious if that stuff really works. i hear when people do the trunk, its supposed to stop the rattles and stuff like that.
