Our review
The Pioneer GM-DC871 is a Class D mono-channel amplifier from Pioneer's Champion Series, rated at 1600W max and 500W RMS. Because it is a single-channel design, it is meant to drive one subwoofer or a combined subwoofer load rather than full-range speakers, and its special bass boost is aimed at listeners who want deeper, more resonant low end. The honeycomb shape and polyhedral structure are there to make the chassis tough and durable, which matters in a vehicle where vibration and heat are constant. Before buying, confirm your subwoofer's impedance and power handling line up with a 500W RMS mono amp, and check whether your head unit has the preamp outputs and crossover control to feed it cleanly. Compared with other mono Class D amps, its appeal is the Pioneer name and the reinforced chassis rather than any published spec sheet, since no detailed specifications are listed here. It is available on Sokonia.
