Fit and use
This product is a factory loaded sealed enclosure (single 12-inch sub). Its shallow wedge profile suits installations with limited mounting depth. The enclosure is internally wired to present a 1‑Ohm load; pair it with an amplifier rated appropriately for a 1‑Ohm load and up to the enclosure's 400W RMS rating. Use the provided 10 AWG quick‑release terminals for speaker cable connections.
What to know
This is a preloaded (loaded) sealed enclosure—no separate enclosure or loose subwoofer is required. The enclosure uses 5/8" MDF construction and quick‑release 10 AWG terminals. Internally wired to 1‑Ohm, it requires an amplifier that supports stable operation at that impedance. The product listing references CEA-2031…
