Just thought i'd add my 2 cents on the whole deadening concept.
I recently did double layers of eDead v1 in my friends 2001 Forester and it helps loads. I would definitely reccomend putting deadener on literally every nook and cranny though. Cover any nonfunctional door holes, but if you do so, put sound deadener on all the metal BEHIND the door holes too if taht makes sense.
