Pioneer GM-DX971 Class-D Mono Car Subwoofer Amplifier

Pioneer GM-DX971 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.

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 ? connection. This design enhances the flexibility to connect multiple subwoofers to a system.

Variable Low-Pass Filter

For extra flexibility, a variable LPF makes audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The GM-DX971 LPF is adjustable from 40 Hz to 240 Hz.

Turn Up the Bass

Every new Pioneer Class-D amplifier has a wired bass boost remote control for optimal bass level adjustment according to listening preferences and music characteristics.

Cool bass

Pioneer’s handsome GM-DX971 mono subwoofer amplifier can deliver up to 1,200 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. And this little workhorse can handle a 1-ohm load, so you won’t have to worry too much about impedance matching when you add another sub to your system down the road.

Connections and tuning for all occasions

Speaker-level inputs allow you to install this amp in a factory system with no RCA connections — the amplifier switches its input mode automatically when it detects the high-level signal, eliminating the need to run a turn-on lead to your receiver or fuse box. The amp’s got a low-pass filter that lets you quickly sharpen and focus the bass to suit your vehicle’s interior, and a wired remote boost that lets you control the amount of bass boost from the front seat. This limited-edition amp uses high-grade electronic parts and gold-plated RCA connections to ensure maximum performance.
