The PS-8 is a powered 8-inch subwoofer in a shallow, low-profile enclosure with a built-in Class D amplifier rated at 150 W RMS. It is designed to fit under or behind a seat where a conventional sub box will not go, and it needs only power and a signal to run. Compared with passive 8-inch subs, it saves you buying a separate amp and box, but it moves less air than a 10- or 12-inch setup. It suits truck, SUV and hatchback owners who want fuller bass without giving up cargo space.
