Set the gain to %50 and see what happens, also make sure the amp is well ventilated and not upside down. It has thermal switches for overheating.

chances are you probably have a bad component(s) inside of the amplifier.

are the subs or speakers 2 or 4 ohm? it sounds like a mono block amp 400X1

remove power from the amp let it sit for a few seconds then put power back to the amp

Your amp is going into protection mode, it might be either overheating, when the bass drops or there may be a wrong connection somewhere in the amp.

Good luck..

Check your battery wire fuse. And check your fuse on your amplifier

rewire the subs-each sub you want in series=8 ohms per sub-then at the amp wire the two 8 ohm subs in parallel which brings the ohms back down to 4 ohms which is optimal for the amp and it shouldnt shut down on you any more-try that-good luck

If the amp is in protection mode, there is either wires touching somewhere or a short. Otherwise the amp itself has an internal problem and would need repair or replacement. If you have any other questions please let me know.
