Check the resistance between the positive and negative terminals of the speakers. There should be atleast 1 ohm of reistance depending on your set up... if there is very little there is a short in your wiring. If not remove the wires from the amp and now check the resistance between the termanls on the amp...there should be no condinuity...if there is your amp has short circited out.

Assuming that you've confirmed that the speaker is in good working order and that the wiring isn't shorted in any way...
There are separate power supplies for the high and low amplifiers. It's possible that the one for the sub output has failed. If that's the case, the output transistors probably failed and that's what damaged the supply.
Generally, I'm willing to help people repair their amps but this is a large, complex amplifier and it should be repaired by a qualified technician.

I would try running the subs in parallel. Pos to Pos Dual Voice, Neg to Neg Dual Voice. Then Run + to + stereo - to - stereo on both channels.
So you have + and - running to one channel and + and - running to the other channel.
Also your LPF filter could be set too high.
