I have an amp separate from my home theater receiver that runs the left and right main speakers. It can be powered on by a 12v trigger. I once had it set up this way but I lost the cable. Question: I thought I remember the cable being a simple, one wire cable connected by rudimentary jacks (small cylinders of metal)and that I could probably make one from some stranded wire soldered to small pieces of heavy gauge wire as the jacks. OR, as I have read here and there, does the cable have to be two stranded and the jacks have to be mono 3.5 mm plugs? I mean, it's just a simple pulse it's sending, right?
