i had my kicker zx850.2 amp running on a long car ride and it randomly shut off and wouldnt come back on. i replaced the remote wire and the rca cables and still nothing. the only time i can power to my subs is when i put one rca cable in the output and one in the input, but the subs still arent getting enough power. when i put both rca cables in the input i get nothing. the amp light wont even come on. can someone please help me?
