What amplifier power does the MJP844 need?

It is rated at 750W RMS, so pair it with an amplifier that delivers close to that at its final impedance. Its low 82.3 dB sensitivity means underpowering it will leave it quiet.

How do I wire the dual 4-ohm coils?

Wire the two coils in parallel for a 2-ohm load, or in series for 8 ohms. Choose the wiring that matches your amplifier's stable impedance.

What size enclosure does it fit?

It needs a cutout of 7.3 inches and 5.6 inches of mounting depth, so it fits small sealed or ported boxes. Check depth clearance before buying.

Is an 8-inch sub worth it over a 10 or 12?

An 8-inch sub fits where larger drivers cannot and still handles 750W RMS. It will not dig as deep as a 10 or 12, so pick it for space, not maximum output.

The subwoofer itself. Mounting hardware and enclosure plans are not included, so plan your box and wiring separately.
