Ok so I found someone selling 2 of these amps and I got a good deal on them. This is the info I have on them. The one amp is in working order he pulled from his vehicle today. The other he pulled from his vehicle a few months ago working. The amp he pulled a few months ago we couldnt get the light to turn on, we just did a in house test on it with a battery charger to see if the light would turn on. He pretty much gave me the amp that the light wouldnt turn on. Im just getting back into car audio so im rusty, is there something I should check on the amp? I dont have my car wired up yet so I cant test it that way yet. Any suggestions will help.
