Well just the other day I was removing a sub from its box and i touched the basket on a positive pole of a 6 by 9 and yes they were on. What did i do? The head unit is fine i replaced the rca cables and the subs and speakers are fine. So the amps are messed up correct or what? If they are what do i do?
You should first check the amps fuses. Your amp kits fuse and any connections. Check with a multimeter if you are getting voltage and current at the back of the car and check if you get continuity threw the speakers. That might give you a better idea of the problem. beyond that idk man good luck.
