I hooked my system up a while ago and it sounded good. Then my rockford fosgate prime 300-4 started flashing power and protect and making the speakers pop. After i fixed it started doing it again and it wouldnt shut off when i turned the car off. There is nothing wrong with the wiring because i tried 2 other amps and they both shut off when the car went off. I really dont know what to do at this point.
