Hey, all.
I'm considering sticking some expanding foam in the space between the felt 'liner' of my 02 WRX wagon rear door and the door itself. I have a large stereo subwoofer in the back, and _something_ in there is rattling. I think it's some of the wiring tapping against the metal of the door. ;)
I'm considering several options, including stuffing some small blocks of soft foam in the space to press the wiring in place, or perhaps even using some of that expanding spray foam.
I don't think there are any 'moving' parts in there, just wiring. So I don't think there's much risk of problems if I gently pack some foam in that space.
Does anyone agree/disagree??
Thanks!!
