i would say check the phase of your speaker wiring.
i think a 270 amp alt should be able to keep the 2000w amp fed

Is your voltage dropping badly at the amp when playing? Check all wires for loose or corroded connections. With an alt that big and only a 2k amp you shouldn't be dropping badly even if your battery was dead.

Northstate battery wired down to one ohm on a crescendo bc2000

What subs are you running? A wire on the sub(s) or in the box may have loosened up and isn't making a connection anymore. Also, a coil may have gone bad raising your ohm load causing a loss in power. Recheck your gain settings as well as any settings in the head unit. There have been a few cases where gain knobs will turn themselves down from vibration. You basically need to go through your entire install and recheck everything from top to bottom.
