Morning Ladies and gents. So I have stripped the interior of my Sierra and am looking to install dynamat before anything goes back in. That being said, I have never messed with it before and would like to know if anyone can help me figure out exactly how much I need and for those with experience with it, can you explain to me how I know what thickness I need, etc. I will not be putting a large system in it or anything like that, but I plan to give it to my son for Christmas and I am sure at some point he will put a system of some kind in it.

Thanks for the help!
