[QUOTE="Heathen, post: 8765572, member: 680849"] I'm chasing the cause of, what seems to me, Ground Loop. I turn the headunit on, and the speakers have a low hiss. Once the media is about to start, the hiss gets louder. *Headunit is new and not faulty (as far as I can tell). *Problem is present for all sources (video, USB, radio) *I've tried earthing the headunit to the same place as the amplifier - no difference *Different RCA cables were used, away from where the existing ones run, and that made no difference either Any other ideas? Of could this interference be something other than Ground Loop? [/QUOTE]
