1-Channel Class D Mono Amplifier

The Pioneer GM-DX871 is a 1-channel Class D mono subwoofer amplifier engineered to provide robust bass performance. It delivers a substantial 800 watts RMS into a 1-ohm load, 500 watts RMS into 2 ohms, and 300 watts RMS into 4 ohms, ensuring powerful and deep sound reproduction. Its highly efficient Class D circuitry not only offers impressive power output but also results in a compact chassis, simplifying installation in various vehicle locations. For enhanced audio control, the GM-DX871 features a variable low-pass filter (LPF) that can be adjusted between 40 Hz and 240 Hz, allowing users to fine-tune the audio frequencies to match subwoofer characteristics and personal preferences. The amplifier also includes Pioneer's Protection Control System (PCS), which continuously monitors input voltage, current consumption, and operating temperature to maintain stable operation under demanding conditions. Additionally, it is equipped with speaker-level inputs, enabling integration into factory head unit systems that lack RCA outputs, and comes with a wired bass remote for convenient bass level adjustments. Included in the box are the amplifier, two 40A fuses, a bass boost remote control with cable, a speaker-level to RCA input adapter, installation screws, a wire terminal tool, and an owner's manual. The amplifier itself is CEA-2006 compliant and has a signal-to-noise ratio of 75 dBA. Its dimensions are approximately 10-3/8" W x 2-3/8" H x 7-7/8" D, and it weighs 6 lbs. The unit is covered by a 1-year warranty.
