I had my system working already, and it sounded good an all,then i got a flat tire, so i had to take everything out, when i put it back in, the pos. wire touched the neg. and it sparked, once i got it all back in it wouldnt work!, i pulled out the headunit, and somehow the Remote wire, and the RCA cables got pulled out of there, so i hooked it all back up right, checked all the fuses. and still nothing... The subs move to the song, so i guess its not the head unit, do u think i fryed the amplifier? One more thing, on one of the songs on the 50 cent CD the subs knock pritty good, but they dont work on any other songs
