Disconnect all speaker wires from the speaker terminals of the amp and disconnect 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.

Why is the red light that says protect on? my amp turns on but it dosent work, i have a sup hooked up & it dosent work. the red light that says protect is on.


first thing check all ground and power wires and make sure ur rca wire make sure it isnt cut in anyway. after that unplug ur sub and unplug the negative wire from ur amp, while its out check the fuses on the amp if all is well put all fuses back if not get new. then plug the negative wire back in if protect goes off check for heat and if no heat inspect the wires from speaker out put all the way to the sub, look for any wire touching another this is were most problems are even the smallest wire can trip a protect. if u still cant find the problem. an amplifier specialist is in order.if its trashed go on ebay and buy a powerbass there goin cheap right now. hope i could help

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.

I have a alpine mrp-m500 for about two years no problems at all. but one day it stops producing sound. i check all fuse on the whole system. is the a protect mode? and how do get it out of it?


If you have checked all the fuses.
Trace your ground wire that goes to the frame. It may be possible your ground is no longer grounded properly. You may just need to unhook the fuse from the battery, Unhook the ground wire from the chassis and restrip, put on a new connector, chisel off the paint around where the amp was grounded to and tighten it back down. Hook back up your fuse to the battery and check and see if it removes the protect light.
Also check to make sure your RCA cables aren't bad. If the RCA cables ground it'll put the amp into protect mode too. Basically just switch out the RCA cables for a good pair.
If the remote wire on the amp is touching the ground, it'll throw the protect light too. That's pretty much the extent, unless the amp has a short inside it.

Hope this helps!

The saftey red light keeps coming on


It means that the subwoofer is blown. The red light is called the Protect light. Disconnect the speaker wire from the amp and then turn the amp on and see if the red light goes away. But if as soon as you hook the speaker wires back to the amp and the red light turns on that DEFINATELY means the sub is blown.

Amp blowing fuses


The amplifier probably has shorted output transistors.

Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).

Amp in protection mode


Disconnect all speaker wires and signal cables from the amp. If it powers up normally (doesn't go into protection), the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.

Protection Light irritation


If the amplifier goes into protect when there are no speaker wires connected to the amp, the amp is likely defective. The most likely culprit is shorted output transistors. If it's new, return it to the place of purchase for repair/replacement.
