Rockville USS8 8" Slim Under-Seat Active Car/Truck Subwoofer — 600W Peak / 150W RMS

Compact powered under-seat subwoofer engineered to deliver full bass without sacrificing cabin space. The USS8 measures just 2.9" thick so it tucks neatly beneath most vehicle seats while housing a high-quality built-in amplifier for a clean, simple installation. Because the amp is integrated, wiring is straightforward and clutter-free. Designed for both aftermarket and factory radios, the unit includes high level inputs so it can be installed even when no preamp outputs are available. An intelligent auto turn-on circuit senses an audio signal and powers the amplifier on; it also shuts the amp off automatically when music stops. All inputs and outputs are consolidated on a single side to make routing cables neater and installation faster compared with many competitor units. Power and performance are verified: the USS8 delivers 600 watts peak and 150 watts RMS and is CEA-2006 compliant, meaning its power ratings are third-party validated. The slim enclosure is voiced to produce the impact of a full-size sub while occupying minimal space. Tone-shaping and protection: onboard controls let you fine-tune the bass to taste — including level control, subsonic filter, variable low-pass crossover, phase switch, input sensitivity adjustment and bass boost. The amplifier incorporates thermal and short-circuit protection plus a soft delayed remote turn-on. Status is shown with a Green Power / Red Protect LED. A remote bass level knob and mounting hardware are included. Build and design: Rockville owns the exclusive mold for this enclosure, featuring a modern aesthetic and reinforced, heavy duty mounting feet for reliable longevity. 90-day money-back guarantee: If you’re not satisfied with the sound, Rockville will provide a prepaid return label and a full refund.
