Protection light keep coming on


Make sure your head unit is off.

Reset the amplifier using the manufacturers specified method. Usually this is just power down briefly and then back up. I usually pull the amp fuse and make sure all LED's on the amp go out. Wait 10 seconds, and then put the fuse back in.

If the LED comes back on when you reconnect power, without the HU being on, you've got a bad amp.

If the LED does not come back on after reset, then check for short circuits on the speaker leads. Still leaving everything off, from the amp terminals, remove both wires to a specific speaker and check for shorts.

If the red light is coming on It mean their is a grounding problem. Also check if the power and ground wire is not cut or broken.

500/1- Low ohm light


Disconnect the speaker wires from the amplifier's terminal block. If the low ohm light still comes on with no speaker wires connected, the amplifier will need to be repaired.

If the light no longer comes on, check the speakers and the wiring.

Xm-6650 led light on short is on and no sound


Disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.

Protection Mode? amp wont start


With your multimeter set to DC volts and the black meter lead on the ground terminal of the amp, touch the red lead alternately to the B+ and remote terminals as the amp shuts down. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low.


If the voltage remains near or above 12v, disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
