This bundle pairs the Rockville RG212CA v2, a slim vented powered subwoofer enclosure with two 12-inch drivers and a built-in 2000-watt amp, with the Rockville RWK81 8-gauge amp installation kit. The slim, vented box is built to fit behind a truck seat or in a shallow trunk where a full-size box will not go. It suits drivers who want a self-contained bass upgrade without buying a separate amp and enclosure. Against passive dual-12 boxes it saves the amp and wiring decisions, but it is a budget-class unit and the 2000-watt figure is a peak rating, not RMS.

Rated 4.5 out of 5 from 68 ratings, owners mostly like the fit and the bass for the size. Complaints center on durability and on the power rating being overstated.
This bundle pairs the Rockville RG212CA v2 powered car subwoofer with the Rockville RWK81 8 gauge amp installation wire kit. The subwoofer is a slim, vented enclosure with two 12" subwoofers and a built-in amplifier. It is about 6" longer than Rockville's single 12" slim enclosure.
The enclosure is built from ¾" MDF, ribbed and braced, with a vinyl finish and side vents tuned to 40Hz. Each subwoofer has a composite pulp cone with Kevlar reinforcement, a rolled steel basket and a laminated rubber surround. A built-in limiter circuit removes unwanted distortion frequencies at peak volume.
The amplifier takes RCA inputs, or high-level inputs if the radio has no RCA outputs. The power, signal and remote turn-on terminals are angled for quick connecting and disconnecting. An adjustable low-pass crossover filters out the frequencies you don't want the subwoofer to play. A remote bass knob mounts near the dash to raise or lower the sub volume.
