Rockford Fosgate Amp...Please Help ASAP

[Kowitz]

I am installing two Rockford Fosgate 401s 1200w amps(one for speakers and one for the subs). I have one working perfectly but the other is not. It powers up, but is producing no sound. I know it is the amp because the speakers worked on the 1st amp, but not on the other, and same with the subwoofers( JL W3v2-D4's).

So the 2nd amp will power up(I can see the light), but there is no sound being produced.

Why is it doing this? Is it blown, or can I fix it. Thank you
