I'm hoping someone hear might have some ideas with what's going on. I uploaded a video so you can see/hear for yourself. When I tighten the speaker against the door, the speaker starts to distort. When I back the screw off, the sounds goes back to normal. But I've had other odd problems with the stereo system so I'm wondering if there's some kind of electrical/ground problem that is causing this. I have posted everything on the RDX board, you can read details here:
AWFUL right-channel distortion at all volumes in 07 Tech door speakers - AcuraZine - Acura Enthusiast Community

Any advice is greatly appreciated.
