One layer of Raamat in the hatch, with a layer of closed cell foam over it. It cut down on the road noise, and the bass does sound clearer. No before or after db readings, though. I'll do the doors, floor and headliner when it's time to redo the stereo. I'm only opening the doors up once. I'm trying to avoid creating rattles.
