The Rockville RVS12A is a slim, vented 12-inch powered subwoofer enclosure with a built-in amplifier rated at 1400 watts peak. It is the louder, vented follow-up to Rockville's RWS12CA, with a bigger box, a woofer tuned to the vent, a stronger amp and a fixed 30 Hz subsonic filter. It suits drivers who want real bass in a trunk or hatch without giving up much cargo space, and it undercuts most name-brand slim powered subs on features. Owners rate it highly for output and value, though some note the bass can sound boomy and the amp is not a true 1400 watts RMS.

Buyers rate the RVS12A well, mostly for the bass it delivers from such a small box and for how easy it is to wire into a stock system. Complaints center on the peak power rating and on bass that can sound loose at high volume.
The Rockville RVS12A is a powered car subwoofer with a 12" woofer and a built-in amplifier in a slim, vented enclosure. It is a vented, higher-powered version of the RWS12CA. The shallow design takes up little space in a trunk.
The amplifier is rated at 1400 watts peak and 350 watts RMS. A fixed subsonic filter removes frequencies below 30 Hz. An adjustable low-pass crossover filters out higher frequencies. For example, if your full-range speakers roll off at 80 Hz, you can set the crossover to filter out everything above 80 Hz.
It has both RCA inputs and high-level inputs. Use the RCA inputs if your receiver has RCA outputs. Use the high-level inputs if it does not, as with a stock radio. The power, signal and remote turn-on terminals are angled for quick connecting and disconnecting. A remote bass knob is included. Mounted near the dash, it raises or lowers the subwoofer volume.
