You mean the roof? I was thinking that but they said it really wasn't necessary.. only on SUV's. I'm sure it would help but I don't think I'mg onna do it, plus it takes too much time, and I ain't got time :mrt: TIME IS MONEY!
you don't need to put it on the roof... my system is pretty loud, and all it ever does is deflect... it never makes anynoise. The back wall is a whole different story. I've got something like 3 coats of dynamatt xtreme on there. Same with the rear and front doors. I also have a bunch on the floor under where the subs go, but there where no rattles their anyways.
I would def. recomend doing the roof. I have done the entire floor, doors, rear wall, and the roof of my ext. cab sierra. It is like getting into an office. it is so quiet, and it is really quiet in the rain. If nothing else it blocks road and wind noise.
my experience with generic brands of dynamatt have been bad. I've used fatmatt and some other brand of stuff. The stuff is a joke, its like over glorified tin foil. And honestly to me, puting 5 layers of cheap stuff isn't worth the time/effort of putting it on and getting it to fit right.
Yeah... well I got some dynamat on the back doors and the back wall, and it sounds better except they "tuned" my amp and now the base doesn't hit as hard. I think they forgot I had a base knob.. I dunno, I'm gonna go back there Monday.
