Noise/Distortion in Right Rear Speaker Only When Vehicle is Running???

[rpr]

Any idea what would cause this? It's driving me nuts.
It is not a constant buzz (like a short somewhere), it sounds like a vibration (like from the door panel) that coincides with the level of sound being played by the speaker. However, with the car off (engine not running), the speaker plays perfectly clear.

Any help?

I had that problem, check your wiring behing the head unit. One of my speaker wires was not completely covered and some of the wire was exposed and was picking up engine noise. I covered it up with electrical tape and problem was solved.
