[QUOTE="BodegaBay, post: 1559694, member: 560141"] Yes, deaden the outer door panel. Then deaden the inner metal skin of the door -- on both sides (the one facing the outer door panel and the one facing the towards inside the car's cabin. I personally don't use plexiglass but others do. They mount it to the inner door skin panel via stainless screws. I don't personally know if the plexi will resonate but others here can comment. Dynaxorb and Deflex are in the same category so their usefulness is subjective. However, "ndpang" in the DIYMA forum noted that acoustical foam seemed to be better vs. Deflex during his subjective listening tess. I do know a lot of home audio/theater speaker manufacturers use acoustical foam in their cabinets and have emperical data showing such improvements. Plus they are vastly less expensive vs. Dynaxorb/Deflex. I personally use acoustical foam in my setup. [/QUOTE]
