About a week ago i took out the midbass amp to send it back to jbl so they can send me a new one, today I put in the midbass amps and everything was good, it played and there was no more pop from the door speakers, while I was driving and listening to it everything shut off, all the amps, crossovers, and the 2xs, nothing had power, no fuses blew, so I drove to school and when I was leaving everything turned on and I was listening to it for about 5 min and then again everything shut off.
