The Rockville RG212CA and RWK81 bundle is the perfect solution for drivers seeking a powerful, space-saving bass upgrade. Ideal for sedans, SUVs, and hatchbacks, this dual 12" powered subwoofer system comes paired with a high-quality 8-gauge amp wiring kit for a complete, ready-to-install experience.

The RG212CA features a built-in Class D amplifier producing 500-Watts RMS and 2000-Watt peak output. Its two 12" slim subwoofers are housed in a precision-tuned vented enclosure, engineered for deep, responsive bass. Despite its dual-driver design, the enclosure maintains a slim profile—just 6.65" deep at the base—ensuring compatibility with tight trunk spaces.

Built-in RCA and high-level inputs make the RG212CA compatible with both aftermarket and factory radios. Smart design touches like a remote bass knob, angled terminals, and an adjustable low-pass filter enhance flexibility and usability. A built-in limiter ensures clean output, even when pushing high volumes. The subs are wired to present a 2-ohm load to the built-in amp, optimizing output power and efficiency.

To complete your installation, the RWK81 wiring kit delivers maximum conductivity and signal clarity with 100% copper RCA cables and a heavy-duty 60A AGU gold-plated fuse. Flexible power, ground, and remote wires allow for easy routing, and the abrasion-resistant PVC jacket stands up to extreme heat and oil exposure.
