So my amp died on me the other day. I went out and purchased an Alpine MRP500. I went to install it(should be plug and play) and got everything put in. However the remote wire won't turn on the amp for longer then 5 seconds. If I hold the wire/screw in the wire to the amp it will turn on and then it will turn off. I know power is getting to the amp because it will turn on but it won't stay on. I checked all the connections and they all seem fine... Any idea why this is going on?

Here is a video that kind of explains what I am trying to say....

Try unplugging the speaker outputs and then give it a try. If it stays on, then you also have a problem with your speakers.

 

Tried that already. Amp still goes off after about 5 seconds.

 

try test with a new fuse block (the one running your pwr wires from the battery to the amp. i had a faulty one and it was doing something similar to urs.

 

Whats the voltage from the amps ground terminal to the amps power terminal? What is the voltage from the amps ground terminal to the amps remote terminal?

 

The M500 has a switch for the power-on type. Check this. Mine had the same thing from when I bought it.
