Question about Alpine MRP-M500 Car Audio Amplifier
I have a new system in my boat. It was working fine and then stopped coming on. I have checked the wires all is good. I am getting 12.8 volts but when I plug it in nothing. I took it out and hooked it direct to my jeep batt and in worked. Any thoughts?

You need to check the Fuse on the Power Wire and check the ground wire to see if has loosened up. Also check Power Wire as well.

SOURCE: can't get my amplifier to work.
My homie had the same problem with his escalade they adapted an rca line adapter from the factory wiring to geta signal to his amplifier and it just wasnt hitting like it should so we installed a new deck and plugged the rca cords right into it and boomboom pow it was hittin like a champ-we figured that the stock premium system that was incoprporated into the truck had some sort of an onboard amp that was filtering the bass from the door speakers and which was limiting the bass output to the rca adapter and thus on down the line to the amplifier- so maybe ya might want to look into getting an aftermarket deck and see if that helps your cause-good luck

SOURCE: Amplifier wont move subs
I dont know if this will help you but start at the deck and make sure that the outputs(RCA) arent crossed over to highpass and do the same at the amp make sure that its set for lowpass- set half gain -bass boost half gain- subsonic minimum - If that doesnt help try using an i pod with an adaptor that you can play it right into the amp this is to see if you are getting signal from the deck to the amp if it doesnt work with an i pod or mp3 plugged directly into it then you may have got you a blown amp going on- good luck with that
