I figured I would stop by here in my quest to solve a very mild speaker crackling noise. My right front speaker (Focal 165vr, hooked up to a Soundstream RUB4.600) has a slight, intermittent crackle. I only can hear it at low volumes, and still is there when speakers are muted.

I am assuming this is a wiring issue. Before I pull off my door, I wanted to see if anyone had feedback on what I should be looking at. Forums across the web have all sorts of different theories. Since I am wired to the existing factory wiring running through the molex in the door, I assume there may be something unique about this I may have to look at.

Anyways, if someone can provide some guidance, it would be much appreciated.
