Make sure that you get both inner and outer skins on the doors, as well as covering up any holes. Doing this will make a substantial improvement in the way the mid sounds.
yeah, thats what i was thinking, especially being such huge doors. i just was seein if anyone had any experience cuz some of those holes are tiny to put mat down in. a real pain in the arss
I've gotten my fair share of cuts working through those, just try to cover as much of the outer skin through those holes as you can. I actually put a few layers around & right behind the mid on the outer skin.
