Evening chaps and lasses, finally getting round to fitting my alpine speakers into the doors of my type r. I have bought some sound proofing (adhesive backed type), but do i insulate the outer skin of the door ie the surface where the door card mounts or do i put the sound proofing into the door and stick it to the inside face of the outer door skin?...............ive also got some diffusers to put behind the speakers.
Any help would be grateful.
