I have a pre amp and it has 3 wires coming out the back +12v/ground/orange(antenna) I thought the orange wire was for 12v ignition I hooked it all up and the leds dont light up right and no sound to the speakers. was I wrong to think the orange wire needed to be hooked up to the 12v ignition?
orange is usually illumination, it gets hooked to orange, so the leds dim when the rest of your lights dim. you should be able to leave that lead unhooked and everything work.
