the problem is the speakers are mounted to the door panel. this is bad for sound and rattles like hell. the problem is that the doors do not have a inner lining of metal. it is just thick plastic. i cut this back where the speakers where going. i dynamated the outer skin and then made a inner panel with wood. i cut the hole for the speaker then covered the whole inner door with dynamate. i also put the dynamate sound absourber behind the speakers to cancel the rear wave from the speaker. this set up rocks and does not rattle at all.
