Check out the photos of my recent install of 200+ sq. ft. of FatMat sound deadening material before my Alpine / Diamond Audio install. Yes, above the headliner was also done, and the inside of the door shells and the back of the plastic door panels.
Here's a photo journal of the mods that I've done to my truck since I bought it. I'll keep the new stuff at the top.
Note: Most of the picture captions are clickable.
