The Rockville RV8.1A is an all-in-one bass package: a single 8-inch subwoofer in a vented MDF enclosure, a matching mono block amplifier, and an amp wiring kit. Rockville rates it at 400 watts peak and 125 watts RMS (CEA-2031), and the cabinet is angled 15 degrees with under-side aero ports to fire bass forward into the cabin. It suits drivers who want added low end without building a system part by part. Against rival bundles that pair a two-channel amp with a generic box, the mono amp and braced, tuned cabinet are the selling points; owners rate it 4 out of 5, with the usual small-sub limits on deep bass and output.

Owners rate the RV8.1A 4 out of 5 and mostly call it a solid value bundle that adds noticeable punch to a factory system. Complaints center on modest output and the limits of an 8-inch sub in a small ported box.
This package pairs an 8" subwoofer in a vented enclosure with a matching mono block amplifier. The amplifier is built for bass rather than being a 2-channel stereo unit. The enclosure uses a quasi transmission line design with an under-side bass reflex Aero-Port system. The vents are on the bottom, and the cabinet is angled at 15 degrees.
The cabinet is bonded, stapled and braced MDF, covered in logo-embroidered tweed carpet. The subwoofer has a polypropylene cone, a butyl rubber surround and an aluminum voice coil. The amplifier has a bass remote, an adjustable equalizer, crossover and subsonic filter, and thermal, short, overload and DC protection. A wiring kit is included.
