It sounds like you blew the amp. I would try to take it somewhere to get it repaired. If you cant get it repaired than you will be stuck buying a new amp.
- After you fix the amp or buy a new one than I would run the subs off both channels and stop running them in parallel. You have the two channels on the amp so you should use them.
- are your subs still good? if one (or both) of them had something go wrong with them i.e shorted vc. then that would definitely cause the amp to go into protection mode. as far as you not being able to get it to come out, you more than likely fired the insides if what i said above actually happened. try hooking one channel up at a time see if that resolves the problem. you may only get one channel to work which would make sense if one is fried.
- 1) Check Power cable,must connect direct to battery.2)use only 4 ohm speaker. check also speaker cable / from amp to speaker,maybe someways short circuit to ground by the set or other.
- Try lowering the power output of the sub-woofer to minimum, and see if it turns back on
- Try wiring your subs using both channels on your amp,
- Electrical is always hard to guess because of variables but it sounds like your protection kicked on due to a short to ground. I assume by what you say that you made no changes and because it was going for a month, it sounds like a connection came loose and touched a metal part of your car or a wire got severed by a seat or a door or? that caused a direct path to negative. Assuming that both amps are properly wired in parallel, I would check every inch of wiring between the amps and speakers first, then check your input connections from the source to the amps. If everything checks, then possibly your amps got too warm and your protection circuit needs to be reset be simply unplugging and replugging all power to both the amps and the corresponding on-off relays which are on separate 12V circuits- the latter is usually in a switched key output from the battery.
