Look for wires that are touching each other like speaker wires or you may have a blown sub

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.

Its in protect mode and wont go back to normal


disconnect everything except the power, remote, and ground. turn off then on. if it goes into protect mode then there's a posibility that the amp if fried. check all the speaker inputs and outputs to make sure that there are no stray wires shorting out. if it stays on then you may have a short on a speaker wire or an auxilary input wire. plug each one in one at a time until it goes into protect mode, then that's the shorted wire or it could be a shorted speaker.

My nitro bmw-486 amp plays but want put out loud sound


I have the same exact amp. And my friend has the smaller 1600 watt amp, and this happened to his. Basically, just start from scratch. Unhook every single wire, and rewire it. If that doesn't work, look at the side of it, and there are a few knobs that you can adjust using a philips head screwdriver. Try adjusting the bass boost knob.

481 doesn't work


did that to mine. Bat went dead and went to jump the car. What happends is when you attach the jumper cables, it surges the power to the amp. This gets worse with caps. I would say you blew the relay in the amp and needs to be replaced. It is worth fixin but youll have to send it off or take it to a repair shop to have the new relay put in

Nitro 1000 w amp


unplug the speakers and the RCA leads from the amp, if the red protection light is still lit then its 1 of your linear amps blown or mosfet depending what your amp uses..if the red light does go off with the leads all disconnected, then connect 1 lead at a time and check the light,when you connect the bad lead or speaker then the light will come on and you know that 1 needs replacing..hope this helps
