Pioneer GMD8701 1600W Class-D Mono Car Amplifier with Wired Bass Boost Remote & 1-Ohm Stability

Product Description

Compact Class-D Mono Amplifier With 1600W Maximum Power & 1-Ohm Stability!

The Pioneer GM-D8701 delivers high-efficiency subwoofer amplification in a compact Class-D design that's 50% smaller than traditional Class-AB amplifiers. This monoblock amplifier produces 300W RMS at 4Ω, 500W RMS at 2Ω, or 800W RMS at 1Ω, providing flexible power options for various subwoofer configurations. The 1-ohm stable circuit design allows connection of multiple subwoofers while maintaining clean, powerful bass reproduction.

The wired bass boost remote control enables real-time adjustment from 0 to 18dB at 50Hz, allowing optimal bass level tuning according to listening preferences and music characteristics. Variable low-pass filter (40Hz-240Hz) with 12dB/octave slope provides precise frequency control for seamless integration with your system. The advanced Protection Control System monitors internal temperature and automatically moderates input levels to prevent circuit shutdown. With MOSFET modulated power supply, high-density split-dome convection heat sink, automatic signal sensing, and speaker-level inputs for factory system integration, the GM-D8701 delivers professional-grade subwoofer performance in a space-efficient package.
