check if the speaker wires are grounded or touching eachother, just one strand can cause problems. if you push in on the subs and they grind or catch, get new subs. if the speaker wires were shorted, you could have blown the amp's signal circuit. try replacing the wire with fresh 12 gauge. if they're DVC subs, replace that wire too. and for god's sake man keep a flashlight in your car.
