The red protect light is coming on

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you.

It is possible that your amp is going over the threshold limit of draining current to give out the protect signal. What could be done is to first checkout if your speakers are loading the amplifier, check the rating of the speakers and the impedance, must not be too low.below 2 ohms. Now check the source signal if this is bringing in any transcient signals to power out the outputs particularily high/low freq. So decrease off your bass and treble to mid position and test again. see if there is any improvement, if so there could be a filter problem with your set. Connect an external source and see if the amp powers better , in such case check for fault in cables, input lines and ground with in the set. Repeat this and check. Hope this helps you out. Good day
