If your subs are BOTH 800rms each, then you are not giving them nearly enough power. Generally speaking it is more dangerous to under power then to over power. You should always be running stereo equipment at rms wattage. just because your amp says 1250 watts.. does not mean you are getting that much.. you could be getting a third of that. I've seen amps rated for 10,000 watts that you woudl only get 400watts out of. If your amp is turning off, then you could start with checking the ground wire or the remote wire.
