What does the 1800W rating mean?

It is a peak power figure, not continuous RMS. Match it to an amplifier's RMS output rather than its peak number.

Will it work with my mono amplifier?

Yes. The 4-ohm single voice coil connects directly to a mono amp stable at 4 ohms, with no series or parallel wiring needed.

It can go in either. A sealed box gives tighter, more controlled bass; a ported box trades accuracy for more output.

For most listeners, one 12 in a proper box adds solid low end. Two are for people chasing higher output and more headroom.

No. It is a bare driver, so you supply the box and wiring.

Dual-coil subs offer more wiring options for high-power amps. This single-coil design is simpler and suits modest setups.
