my amp has power, a great ground, turns on with head unit, so my main 3 connections are fine, I thought my RCA's may have been bad, but I connected them to another amp and they were fine, I have no sound coming out, my speakers also work fine, tried them with a different amp...is there a way I can modify my speaker terminals? or is this something I would need to contact kicker about and see if I could send it in for repair
