Question about Car Audio & Video
Generally if your amplifier goes into protect, you have a bad ground.
Unhook your power wire from the battery and trace your ground wire to the chassis of the vehicle. Strip the paint from the ground location, Put the ground wire back on the grounding location. Tighten the ground wire down securely with no play and hook back up your power wire.
Other cases revolve around the RCA cables.
Unplug the RCA's and see if the protect light goes off.
Plug one in and see if the protect light comes on and then the other.
If the protect light comes on, you have bad patch cables. Replace them and see if your issue is resolved.
If the amplifier was shorted, the system board made have been damaged.
