also be sure to put Dynamat around the speaker housing for the front speakers and dynamat on the rear deck sheet metal. It sure eliminated the rattling I got after replacing all of my speakers. You can go further by putting Dynamat on the doors, floor, trunk and roof, but I'd only put that much Dynamat in a better car, say a Matrix.
