I've done quite a bit of research up till now and I've found that it seems Butyl based deadeners are the ones of choice and now im wondering how how much ill exactly need. I have a 05 silverado ext cab and the roof is quite noisy from all the flexing and rattling I feel sorry for it almost. But I think im gonna go with Second Skin deadening . Now the owner recomended I use 2 layers of damplifier pro which is 90mils thick but a friend said thats to much which the regular damplifier is 65 mils just like dynamat extreme . I just wanted to pool opions on how much to use system is in the sig also my box is downfiring but I may try up firing soon .
