This Rockville car audio bundle pairs the RVB12.1A powered subwoofer enclosure with the RWK10 wiring kit to support a complete low-frequency upgrade in cars and trucks. The combination is designed for users who want strong bass output without sacrificing large amounts of cargo space or installing multiple separate audio components.

The RVB12.1A houses a 12 inch subwoofer and a built-in Class AB amplifier inside a compact, angled enclosure. The cabinet design allows it to sit closely against rear seats while keeping enclosure volume under two cubic feet. A computer tuned bass reflex port and side-mounted aeroport help low frequencies develop inside the vehicle before entering the cabin.

The integrated amplifier delivers up to 300-Watts RMS with adjustable low pass crossover and bass boost controls. High level speaker inputs allow installation with factory head units that lack preamp outputs, while low level RCA inputs support aftermarket systems. The enclosure uses an anti-vibration MDF cabinet, reinforced cone materials, and stitched surround construction.

Subwoofer Size: 12 inch active powered enclosure

Amplifier Type: Built-in Class AB amplifier

Frequency Range: 30Hz to 150Hz

Input Options: High level speaker and low level RCA

The included RWK10 wiring kit supplies properly sized 10 Gauge power and ground cables, copper RCA signal cables, fuse protection, and installation accessories. Together, this bundle supports a straightforward powered subwoofer installation for vehicles needing deeper bass without complex system layouts.
