An amplifier shouldn’t take up too much space, especially in your car. The GM-DX874 might just be what you’re looking for. It combines a 1-Ohm stable circuit, installation flexibility and a superior high-power output partnered with “Hi-Res” certification for those of you who only like the best!

"Hi-Res" Audio Certified
Pioneer’s new GM-DX874 Class-D digital amplifier is equipped with high-quality sound components and tuning, compatible with "Hi-Resolution" audio for the highest quality sound reproduction. It's the perfect partner to Pioneer’s exclusive speaker range, TS-Z Series!

The product with the Hi-Res AUDIO logo conforms to the High-Resolution Audio standard defined by the Japan Audio Society. The logo is used under license from the Japan Audio Society.

Big Power, Small Size
Pioneer’s new extra-efficient Class-D digital amplifiers offer a dramatic improvement in power output capability while being 50% smaller than the current GM-Series Class-AB amplifiers. This makes them more versatile in terms of installation and performance.

Improved Circuit Design
Pioneer’s new digital amplifier circuit, the "Protection Control System," prevents circuit shutdown by sensing its internal temperature and automatically moderating input level accordingly. Stable, durable circuitry lessens the risk of high input power for the unit to achieve 1 ohm connection, enhancing flexibility to connect multiple subwoofers to a system.

Variable Low Pass & High Pass Filter
Variable LPF and HPF provide extra flexibility, making audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The LPF and HPF are adjustable from 40 Hz to 500 Hz.

High-Level Inputs
Don't own a Pioneer head unit? No problem! Speaker level inputs allow you to connect your OEM unit (or any unit without typical RCA-type inputs) without needing add-on adapters. This speeds up the in
