kicker amp problems kx650.4

I am running a Kicker KX650.4 amp. Its 4/3/2 channel and I am running it as 2 channel. I have one sub running to the amp1 channel and one sub running to the amp2 channel. I am using the high level signal inputs with the rca dummy plugs in the amp 2 input (per the instruction manual). I am using both sets of high level inputs (1 for amp1 and 1 for amp2). The subs I am using are 12" kicker L5's dual 4ohm coils. When I turn the system on, there is almost No sound coming from the subwoofers. The indicator lights are green, so there shouldnt be a problem. What could the problem be. I wired the coils like the instructions said (series). I checked the ground and it was .09 ohm. The main power coming into the amp was 12.6 volts. The remote turn on read 12.6 volts also. I am using 4 gauge wiring for the power and ground and 16 gauge for the remote wire. The speaker wire is 12 gauge.There is almost no sound coming from the sub.
