well the one thing I see as your main problem is you set your gain by ear even a little bit can be enough on certain songs to clip the signal being sent to the sub heating it up quick, reset the gains the right way and fix any burnt wiring and see if it helps but you may have shaved/cooked some life off the epoxy coating on your vc's.
