The Pioneer GM-DX871 is a compact Class D mono subwoofer amplifier that delivers powerful, efficient bass performance in a space-saving design. Producing up to 800 watts RMS at 1 ohm, it provides the clean, controlled power needed to drive today's high-performance subwoofers. With a variable low-pass crossover, adjustable bass boost, speaker-level inputs, and an included wired bass remote, the GM-DX871 offers flexible installation and easy bass level control, making it an excellent upgrade for factory or aftermarket car audio systems.
