Is the HD12D2 worth it over a cheaper 12-inch sub?

If you already have an amp that makes around 1,500–2,000W RMS, the cast basket and cooling vents are real steps up from budget stamped-basket subs. On stock electrical and a small amp, a lower-power sub will sound better for the money.

What amplifier power does it need?

Plan on roughly 1,500–2,000W RMS at the impedance you wire it to. With dual 2-ohm coils you can wire to 1 ohm or 4 ohms, so pick an amp that is stable at your target load.

What size box does it need?

It is designed for a ported enclosure, and the 8.38-inch mounting depth plus 53 lb weight mean a substantial box. Expect a large trunk or SUV cargo area build rather than a compact sealed box.

Can I wire it to 1 ohm?

Yes. The two 2-ohm voice coils can be wired in parallel for a 1-ohm load or in series for 4 ohms. Make sure your amplifier is rated for the load you choose.

The subwoofer itself. Enclosure, wiring and amplifier are sold separately, so budget for a ported box and suitable gauge wire.

Our take on the American Bass HD12D2 12 inch 2000W Car Audio Subwoofer

The American Bass HD12D2 is a 12-inch car subwoofer rated at 2,000W RMS and 4,000W peak, with dual 2-ohm voice coils. It uses a cast basket with a blue powder finish, perimeter vents for voice coil cooling, and a free-air resonance of 37 Hz. It is built for ported enclosures and weighs 53 lb with an 8.38-inch mounting depth, so it needs real space and solid power. It suits people moving up from mid-tier subs to a high-power daily setup.
