- Can I wire this sub to 2 ohms?
- Yes. The dual 4-ohm voice coils wired in parallel present a 2-ohm load. Wiring them in series gives 8 ohms.
- What size enclosure does it need?
- It is a 12-inch driver, so it needs a box sized for a 12-inch sub, typically a sealed or ported enclosure built to Alpine's recommended volume.
- Does it work with a factory stereo?
- No. It has no built-in amplifier, so it needs a separate amplifier and wiring from the head unit.
- Is it suitable for a boat?
- No. It is designed for car use, not marine environments.
- What is in the box?
- The subwoofer itself. Amplifier, wiring and enclosure are sold separately.
- Where is the Alpine hdz-w12 12" status series dual 4-ohm car subwoofer cheapest?
- At Best Buy, for $999.95, as of our latest check.
