Is the NVX VSW124v3 worth it?

For a budget 12-inch sub with 600W RMS handling and dual 4-ohm coils, it is a reasonable value. It makes the most sense if you already have an amp that does 500 to 800 watts at 2 ohms.

What amp should I pair with it?

Look for a mono amp rated around 600 to 800 watts RMS at 2 ohms, since the dual 4-ohm coils wire to a 2-ohm load. Its 86 dB sensitivity means extra headroom helps.

Sealed or ported box?

NVX lists 1.0 cubic feet sealed and 1.85 cubic feet ported. Sealed gives tighter, smaller-footprint bass; ported plays louder and lower but takes much more trunk space.

Can I wire it to 2 ohms?

Yes. The two 4-ohm voice coils in parallel give a 2-ohm load, or in series an 8-ohm load. Match the wiring to your amplifier's stable impedance.

Will it fit my enclosure?

It needs a cutout of 11.22 inches and 6.45 inches of mounting depth, so measure your box before buying. Shallow boxes under about 7 inches of internal depth will not work.
