He needs to confirm that he has both B+ and remote turn-on voltage at the amp.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

Hello beaugarcia26,

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.
