either over driving the amp or there's a short somewhere or you wired the subs wrong. Gain settings at minimum can still overdrive an amp if the head unit's pre-out voltage is strong enough that means you already telling the amp to make more power than its capable of and its giving a dirty signal generating a lot of heat causing the amp to trip multiple protection circuits.

Try unhooking the subwoofer and only play the mids and highs. If it still does it then you can eliminate the subs being wired wrong.

Make sure your EQ is flat, Loudness is off and no bass boost on the head unit.

If its not the ground then you might have a short somewhere in your speaker wiring or speaker wires get cut and stripped somewhere and its shorting out with the car as a ground.

Alrighty then. The issue has been solved with that. Thanks to everyone for the help. It turned out to be when we put the door speaker back in, a screw caught the wire and shorted it out. Fixed that and now she stays playing! How about amp settings for the speakers (front component and rear deck), anyone wanna help with that? My old settings for the sub are perfect.
