Get that instead of Dynamat, it is a better bang for your buck. I would say at least 1 layer on the whole car (doors, floor, roof, hatch etc.) and than possibly double up on the hatch and the roof above the hatch. Check my build to see my install of this stuff. Also what kind of electrical are you going to have? That amp is power hungry so I would say at least (2) runs of 1/0 wire, a decent battery under the hood and a good battery or 2 in the back.
