SOURCE: Correct settings
I am not familiar with your amp, but any amplifier performs best when the output stage effective resistance exactly matches the load resistance. So, read your 15" subs and find out number of ohms, then set the amp to that number. according to your amp's specs: if you have 2 ohm speakers, you can draw 350 watts from your amp. so purchase 2 ohm speakers

Make sure the amplifier setting "disable" is off then turn off remote power and turn back on.

If you have a dual voice coil sub, make sure that you have the positive and negative terminals connected properly. If you have ONE of the coils wired backwards, it will cause the speaker to produce little or no sound.
Have you set the gains properly?
Are you sure the amplifier is receiving a strong signal from the head unit?
Have you tried it with a different speaker?
