I have been driving myself crazy trying to figure out this humm sound. I thought it was from PAC converter Im using.
I checked the RCA cables tonight, and the front cables are the culprit. They are brand new Street Wires Zero Noise series cables. What I dont understand is how I have this issue with brand new cable. (heres a link to them, http://www.crutchfield.com/p_211ZN52...er-reviews-tab
Now I need to get a new set of patch cables, I have RF cable running to Sub amp.
Anyone suggest a good inexpensive 11 ft Patch cable?
