Still a little fuzzy here....you're not trying to run the amp off of the power from the radio are you? If you are it will not work. The cables on the radio (pos/neg) are usually like 16gauge...your amp will require a much larger gauge wire. In fact...if the cable is too small the amp will turn on for a sec (maybe even just light the light) then go dead.
Holy confusing....might want to restate that question...ther is no power per se on the output/input....I suppose signal is DC voltage but I don't think thats what you meant. Remote wire has minimal power it is designed to turn the amp on and off with the ignition...check the main power cables red and black usually. Be careful..it can scare ya good....lol Good luck...
