i havnt checked the hu settings yet but i was screwin around with it for about an hour or so the rca plugins were all ****ed up so i opened the amp an did the best i could to soder it back. theres no smoke tho, im just stumped how some little douche hooks his sub up to my amp plays with a few knobs an now my ****s ****ed. pisses me off. does anyone know how much it would cost to send it to usamps for a repair if they even do that?
