any other amps in the system? if so, try plugging the rca's going to those amps to the sub amp. or........this maybe a shot in the dark, but.....are the subs hooked up in the box?ive had one come loose once and it was a pain trying to figure it out. try another set of speakers from the speaker outs on the sub amp to make sure there is some kind of signal coming out of it.
i have one set and i just returned my headunit and bought another one and its doing the same dam thing!
you have to find out what your subs are... are they 15" dual or single 4ohm coils? or dual or single 2ohm subs? I think you have them wired wrong and the impedance is too low for your amp. your amp can only handle a 4ohm load according to the link that you provided.
