SOURCE: !!!red protect light is on!!!
Unless the amp itself is defective, there's a short or ground somewhere.
First disconnect the speaker wires and RCA (or high level) inputs, leaving just ground, remote turn-on and power leads connected. Then see if the amp powers up normally. If it doesn't check the ground with a multimeter and make sure it is good. If the amp powers up normally, check the speaker, speaker wires and inputs for shorts or grounds.
Hope this helps.
