Is 1200 watts RMS or peak?

It is a peak rating. Real continuous output per channel is much lower, so match it to speakers with modest power handling.

Hifonics states the Super D-Class design is stable from 4 ohms down to 1 ohm. Check your speaker impedance and wiring before running that low.

Can I bridge it to power a subwoofer?

Yes. Bridging two channels combines their output for a single subwoofer, leaving the other pair for speakers.

Yes, it has electronic crossovers so you can filter low or high frequencies per channel pair.

Expect the amplifier and its mounting hardware. Check the listing for included wiring, since amp kits are usually sold separately.
