The Rockville RV8.1A is an all-in-one bass package: a single 8-inch subwoofer in a vented enclosure with a built-in mono block amplifier, rated at 400 watts peak. The enclosure is angled at 15 degrees with bottom-mounted vents, which Rockville says pushes bass forward and gives punchier output than a flat box. The amp is CEA-2006 compliant, a rated-power standard many budget packages skip. It suits someone who wants added low end in a car or small space without matching a separate amp and box, and it competes on convenience rather than audiophile refinement.

The Rockville RV8.1A is an all-in-one bass package. It includes a single 8" subwoofer in a ported enclosure, a matching mono-block amplifier, a bass remote and a wiring kit. The subwoofer is rated at 400 watts peak and 125 watts RMS (CEA-2031). The amplifier is CEA-2006 compliant.
The enclosure has a quasi transmission line design with an aero-port system on the underside. It is angled at 15 degrees. The cabinet is bonded, stapled and braced MDF, covered in carpet embroidered with the logo. The subwoofer has a polypropylene cone, a butyl rubber surround and a 1.5" four-layer aluminum voice coil.
The amplifier is a Class A/B mono-block with a subsonic filter, a low-pass crossover and a bass equalizer. It accepts RCA or high-level speaker inputs and has auto-start turn-on circuitry for OEM integration. It also has thermal, speaker short, overload and DC protection. After a thermal shutdown it restarts on its own once it cools down.
