The Rockville WHEEL OF BASS is a powered 8-inch subwoofer in a slim enclosure that stands about 3.15 inches tall, so it fits under most seats or in a trunk. The amplifier is built in, and high-level inputs let it tap a factory or aftermarket stereo without preamp outputs. A signal-sensing turn-on circuit switches the amp on and off with the music. It is a space-saving way to add low end to a stock system, though at 125 watts RMS it will not match a full separate sub-and-amp setup for output.

The Rockville WHEEL OF BASS is a powered 8-inch subwoofer with the amplifier built into the enclosure. The enclosure is solid cast aluminum and only 3.15 inches tall, so it fits under a seat or in a trunk. It has heavy-duty mounting feet.
It is rated at 500 watts peak and 125 watts RMS. It takes either low-level RCA input or high-level input, so it can be installed with a factory or aftermarket system, even when no preamp outputs are available. A smart turn-on circuit senses an audio signal and switches the amplifier on, then turns it off when the signal stops. All inputs and outputs are on one side of the enclosure for neater wiring.
Controls include level, subsonic filter, low pass crossover, phase, input sensitivity and bass boost. A metal remote bass knob and mounting hardware are included.
