Pioneer GM-DX871 Class-D Mono Car Subwoofer Amplifier

The Pioneer GM-DX871 is a compact Class-D mono amplifier designed to deliver powerful, efficient bass performance. It produces up to 800 watts RMS at 1 ohm while maintaining a smaller chassis and cooler operation than traditional Class-AB designs. The variable Low-Pass Filter can be adjusted from 40 Hz to 240 Hz, while the wired bass boost remote provides up to 18 dB of adjustment at 50 Hz for easy tuning from the driver's seat.

Pioneer's Protection Control System monitors input voltage, current consumption, and operating temperature to help maintain stable performance during extended use and in high-temperature conditions. Speaker-level inputs allow the amplifier to integrate with factory audio systems without requiring RCA connections, and the amplifier automatically detects high-level signals to simplify installation. With high-quality electronic components, gold-plated RCA connections, and flexible 1-ohm operation, the GM-DX871 combines compact size, efficient power delivery, and versatile tuning for a powerful car audio upgrade.
