This bundle pairs Rockville's RVS12A, a 12-inch slim vented powered subwoofer enclosure rated at 1400 watts peak, with the RWK81 8-gauge amp installation kit that includes 100% copper RCA cables. The RVS12A is the vented, higher-output step up from Rockville's RWS12CA, built to add bass to a factory system without giving up much cargo space. It suits drivers who want a self-contained powered sub and the wiring to install it in one purchase. Against sealed slim subs it trades a little tightness for more output; against premium brands it undercuts on features per dollar, though owners of budget powered subs often note modest amp headroom and plain enclosure finish.

Owners of Rockville's slim powered subs generally report a solid bass boost for the money and simple installation. Common complaints center on optimistic power ratings and boomy sound in small enclosures.
The Rockville RVS12A is a slim, powered 12-inch car subwoofer in a vented MDF enclosure. It is a vented, slightly larger and more powerful version of the RWS12CA. The shallow enclosure is designed to take up little space in a trunk. The woofer is tuned to the vent's frequency, and the built-in amplifier delivers 350 watts RMS.
The amplifier has RCA inputs and high-level inputs. Use the RCA inputs if the receiver has RCA outputs. Use the high-level inputs if it doesn't, such as with a stock radio. The power, signal and remote turn-on terminals are angled for quick connecting and disconnecting. A fixed subsonic filter removes frequencies below 30 Hz, and an adjustable low-pass crossover filters out higher frequencies. For example, it can be set to cut everything above 80 Hz if the full-range speakers roll off there.
A remote bass knob mounts near the dash and raises or lowers the subwoofer volume. The bundle also includes an 8 gauge amp installation wire kit with 100% copper RCA cable.
