My pioneer 6x8 3 ways rattle alot when they have bass so I was going to get some dynamat but it's kinda costly. I was wondering if there was any other good product I can use thats cheaper or just spend alittle more and go with dynamat and if so which kind would work for me I just want good sound so should I get the door speaker kits or just the 4sq rolls and put them in the doors?
