3512-02 12-Inch Car Subwoofer Pair + RD12 Sealed Enclosure + Installation Kit

The 3512-02 dual-subwoofer package pairs two 12-inch, 250W RMS car subwoofers with a sealed dual-woofer enclosure and the hardware needed to wire the setup. Each 2-ohm, single-voice-coil subwoofer handles up to 500W peak, with a 26Hz to 130Hz frequency response for low-frequency playback. The enclosure uses 3/4-inch MDF, precision-cut openings, and a sealed design, with 1.25 cubic feet of net volume per sub. Its included installation kit has 20 feet of blue 14 AWG speaker wire, 20 metal screws, and four spade terminals. The woofer's inverted surround increases surface area for air movement, while its suspension controls excursion at higher power to reduce distortion. Cooling airflow directed toward the voice coil supports thermal performance during extended listening. This bundle suits a car-audio build that calls for two 12-inch subs, a sealed enclosure, and basic connection hardware in one package.
