Hello, new to the forum. Today i attempted to wire a new head sony Sony MEX-N5000BT a hifonics 1500d amp and a pioneer 12" subwoofer. I got everything wired up turned the key and i was super excited it worked. But i decided to go for a drive and as soon as i started my truck my sub went dead. My amp is running my head unit has power and speakers play just no sub. Please does anyone know what a problem could be? Like i said it works and bumps hard on the on position with the key but when the truck is running no sub???
