What power does the ZR2000.1D make?

It is rated at 2000 W RMS at 1 ohm, 1300 W RMS at 2 ohms and 800 W RMS at 4 ohms, with a 6000 W peak rating at 1 ohm.

Can I adjust the crossover?

The low-pass filter is fixed, so you cannot change its frequency. You do get a subsonic filter, 0-12 dB bass boost and a 0-180 phase switch.

Yes, a bass knob is included so you can adjust bass level from the front of the car.

It is a monoblock stable to 1 ohm. A 1-ohm final load gets the full rated power; 2-ohm and 4-ohm loads get less.

It is a standard monoblock install: power, ground, remote turn-on and speaker wiring. Plan for heavy-gauge power cable to support the current draw.

It offers more rated power for the money, but premium amps typically add adjustable crossovers and more tuning features.
