The Rockville W8T4-S2 is an 8-inch shallow-mount car subwoofer built for tight spaces: under seats, behind seats in trucks, and in custom enclosures where a full-depth driver won't fit. It is a single 2-ohm voice coil driver rated 250 watts RMS (CEA), 500 watts program and 1,000 watts peak, so it pairs with a modest mono amp rather than a big one. Its slim mounting depth is the main draw against standard 8-inch subs, which need deeper boxes. Owners rate it highly for the output it makes from a small, shallow box, though it is a budget sub and won't match premium shallow drivers on refinement or deep low-end extension.

Owners rate it 4.9 out of 5 and mostly praise the bass it produces from a shallow box in tight installs. Complaints are few and center on it being a small sub with limits at the very bottom end.
The Rockville W8T4-S2 is an 8-inch shallow mount car subwoofer with a 2-ohm single voice coil. It has a mounting depth of 2.5 inches, so it fits where standard-sized subwoofers can't, such as behind the seat in a compact car or pickup truck, or in a motorcycle's saddlebags.
It is rated at 1,000 watts peak, 500 watts program and 250 watts RMS (CEA-2031 compliant). The three ratings let you match it to amplifiers from brands that rate power in different ways.
The cone is an ultra stiff paper composite with a 3D molded high gloss acrylic dust cap and a laminated butyl rubber surround. The basket is slim, expanded and rolled steel. The motor combines a strontium magnet, a high-BL motor gap and a vented core magnet structure with extra thick back and top plates. A large-diameter, progressive-roll spider adds linearity. The high-temperature aluminum voice coil former helps keep the woofer cool.
