Actually Sound Deadner isnt that hard to do and taking panels off on newer cars is generally pretty easy (at least in my ride lol) most new ones are just clipped in so at the most u'd need a panel popper, screwdrivers, and some sockets, if you wanted to go all out and deaden the whole car.
EDIT: look at Second Skin for Sound Deadner, less than dynamat and better IMO
