The QBUS10P is a self-contained 10-inch powered subwoofer in a low-profile ported enclosure, built to slide under a seat. Its Class-D amp is rated 200W RMS (500W peak), and it includes a wired remote bass knob, variable bass boost up to +12 dB at 45 Hz, and both RCA and speaker-level inputs with signal sensing for automatic turn-on. The die-cast aluminum heat sink and fiberglass cone are aimed at durability in tight, hot spaces. It suits drivers who want more low-end without giving up cargo room; against rival under-seat subs it stands out on input flexibility and the included remote, though a 10-inch ported box is bulkier than slim 8-inch units and won't fit every seat.
