Pioneer GM-DX871

The Pioneer GM-DX871 is a powerful and compact Class D mono subwoofer amplifier designed to drive your car's bass with precision. Rated at a maximum of 1,600 watts, it is engineered for high efficiency and stability, even at a 1-ohm load. It features high-quality audio components, including gold-plated RCA terminals and high-current circuitry, to ensure clean, distortion-free sound.

Product Highlights

• Massive Bass Power: Capable of delivering up to 800 watts RMS at 1 ohm, providing enough juice for high-performance subwoofers.

• Efficient Class D Design: This technology allows for a chassis that is 50% smaller than traditional Class AB amplifiers, making it much easier to install in tight spaces like under seats or in small trunks.

• Total Vibration Control (TVC): Uses a specialized heat sink structure and optimized mounting points to suppress vibrations, protecting the internal circuitry and maintaining sound quality.

• Protection Control System (PCS): Continuously monitors temperature and input levels to prevent overheating and circuit shutdowns during long listening sessions.

Key Features

• Variable Low-Pass Filter: Adjustable from 40 Hz to 240 Hz, allowing you to fine-tune the audio frequency to match your specific subwoofer's characteristics.

• Wired Bass Remote: Includes a remote knob that lets you adjust the bass boost (0 to 18 dB at 50 Hz) directly from the driver's seat.

• Speaker-Level Inputs: Features automatic signal sensing, meaning you can integrate this amp into a factory system without needing to run a separate remote turn-on wire.

• High-End Build: Features a textured aluminum panel and a tough frame for durability, alongside gold-plated RCA terminals for better conductivity and corrosion resistance.
