Pioneer GM-DX871 new extra-efficient Class-D digital amplifiers mark a dramatic improvement in power output capability, yet are 50% smaller than the current GM-Series Class-AB amplifiers. That makes them more versatile in terms of installation as well as performance.



Pioneer GM-DX871 mono subwoofer amplifier can deliver up to 800 watts RMS to your subwoofer, for powerful bass that’ll give every song a strong and heavy beat. Highly efficient Class D technology keeps this powerful amp running as cool as it looks, and allows for a small chassis that fits in a lot of out-of-the-way spaces.

Improved Circuit Design

To prevent circuit shutdown, Pioneer’s new digital amplifier circuit “Protection Control System” senses its internal temperature and automatically moderates input level accordingly. Stable, durable circuitry lessens the risk of high input power for the unit to achieve 1 Ω connection. This design enhances the flexibility to connect multiple subwoofers to a system.

Variable-Low Pass Filter

For extra flexibility, variable LPF make audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The GM-DX871 LPF is adjustable from 40 Hz to 240 Hz.
