I've finally got all of my stuff connected for my HTS. Before I push the entertainment center back against the wall, I'd like to clean up the "jungle" of wiring back there. Its seems like I remember something about keeping certain wires away from others to avoid interference. Before I start zip-tying stuff together, I need to know what wires can be lumped together...and which ones need to be away from each other. My thinking is, keep all speaker wires together, all power cords together, and all composite/component together. Is this right?
