Alright i have an old school punch 500. I am using monstor RCA'S ran down the passenger side of my Cobalt to the trunk. I have a 1farad cap as well. My remote wire is hooked up to the power steering fuse, and ran down the center of the car. All power wires are in the trunk. All was working well, then one day i start getting this extreme bass and full excursion from my p3 12...and there wasnt even any music on. Also you can hear the gears shift through the sub, and you can hear the turn signal also. It has gotten to where it won't even play music, it just does its "super excursion" feedback Is this problem likely because of how I have it remoted? Thanks in advance, and if you have any questions ask, and i'll answer.
