step by step
ok you know the amp works, so next check that there is actually voltage on the terminal at the amp, measure this against the ground terminal on the battery just to be sure. if you got voltage there, check it against the ground terminal on the amp, no voltage means your ground connection is shitty (mounted on paint or a piece that happens to be insulated).
if you dont have a volt meter you can use a 12 volt bulb or something. if there is no voltage the in-line fuse is blown or inserted incorrectly. a new piece of heavy gauge amp wire shouldnt be too expensive, give than it doesnt have to go far.
Edit: if the plus and the ground wire check out fine, check the voltage of the REM cable, some work on 5 volts some on 12 i think, if it takes 12 volts you can hook it up to the battery to test it.
