Hey Everyone, Im debating on wheter or not to install dynamat on my expo. I just upgraded the speakers and was wondering if anyone would recomend doing this. Does it make a big difference> How much does the stuff cost and how much should I get. Also whats better the spray on kind or the rolls?
Thanks OH ya one more thing, what is the general purpose of dynamat?> DOes it increase sound quality of sound volume or what?
