Ok check all your connections starting with the power, ground, and remote then check the wire running to the subs. If you don't find any issues move onto the sub (dual or single voice coil?) make sure that it is configured/wired appropriately. If you still find not issues then grab a DMM and check the voltage at the amp (let me know if you need help with this). Make sure your amp is secure/screwed down. Let me know....
