So I've had my subs for about a year now, and recently my amp started cutting out and now it doesnt turn on. If I reconnect everything, pull all the fuses out and put them back in, the amp will power up and immediately shut off. I don't know what is causing this. I have my turn on wire under my accessory fuse. That fuse is good. I checked by using that fuse in another slot and it works fine. My ground is connected to my chasis in a pretty good spot. I also put my amp in my brothers car and it worked perfectly and we have the same set up. What are my possible problems?
