PDX 4.100 Amp not playing

[mikebik]

I have a amp problem it was working fine the other day i went to use it today and nothing is playing. the light is blue and i turns on when i turn the headunit on. i have tried a sepreat speaker to see if the speakers are bad and nothing. i disconnected the ground on the battery that it's and and i plug it back on and nothing but the blue light. the battery that it's on is fine i have tested it already. i cant figure out what it is

It could be a lot of things...check your rca connects, check the outputs on the amp going to the speakers, check your headunit..if you have another amp try that one, and if it works then you know the alpine amp is the problem...also should have posted in amplifier section
