Ok, to start off. I just installed two 10AQHDC3s in my truck powered by a saz3000d. Im loving how loud and strong the bass is but im having trouble enjoying it really. Im getting lots of rattling and roof flex. I was wondering how many sq. ft. of Damplifier Pro would be needed for my truck. Its an 02 gmc sierra extended cab. I have read through alot of forums and all seem to say SS is by far the best deadener but I have never deadened any vehicle and not sure what I need. Thanks for any and all info. Also how many layers and where.

The rattling may not be coming from your roof. Where panels are touching each other and can vibrate could cause a rattling noise. It can be frustrating to track down. Stay by removing panels until you track down the culprit. There are multiple methods available to prevent panel vibrations, good luck.

i would start with a minimum of 10sqft on the roof alone

Thanks for the replys guys. Any chance someone from Second Skin could chime in?
