Is the HFX12D4 a dual voice coil sub?

Yes. Each sub has dual 4-ohm voice coils, so you can wire each driver to 2 or 8 ohms.

How much power does each sub handle?

Hifonics rates each at 400W RMS and 800W peak. Match an amp to the RMS figure for daily use.

What size enclosure does it need?

It is a 12-inch driver with high excursion, so it needs a fairly large sealed or ported box. Check the recommended volume before building.

Can I run four of these on one amp?

Yes, if the amp is stable at the combined impedance. Four dual 4-ohm subs can be wired to a 2-ohm or 8-ohm load.

Is it good for sound quality or just volume?

It leans toward output. For tight, accurate bass, higher-end drivers do better.

Our take on the HIFONICS HFX12D4 12" 800W Car Audio DVC Subwoofers Power Bass Subwoofers, 4 Pack

The Hifonics HFX12D4 is a 12-inch dual-voice-coil car subwoofer rated at 400W RMS and 800W peak per driver. It uses a high-excursion rubber surround, a large air-cooled magnet assembly and a chrome-stamped steel basket. It suits budget builds and multi-sub setups that want output over refinement. Against pricier 12s it gives up some excursion control and low-end accuracy, but owners rate it well for the output it delivers.
