I have door rattles, but only when I have the stereo sound levels pretty high. I plan to use audio matting on the inside skin of the door (Dynamat or Fatmat), and some adhesive neoprene on the inside of the plastic panel.
One thing you should check: the screws in my doors (the ones behind the interior door handles) were fairly loose from the factory and tightening them made a difference in my car.
