DS18 G1800.4D GEN-X Full-Range Class D 4-Channel Amplifier 1800 Watts

The DS18 G1800.4D GEN-X is a 4-channel full-range Class D amplifier delivering up to 1800W peak, built for serious car-audio enthusiasts who demand scalable power and precise control in a compact chassis. Its Class D design has undergone rigorous sound quality verification using AP Instruments, and the G Series is engineered for professional-grade sound reproduction.

• 4-Channel Full-Range Class D: Four independent channels provide full-range amplification, enabling a complete front/rear speaker setup from a single unit.
• 1800W Peak Power: Total maximum output across channels when driven to the limit, providing dynamic headroom for transients and loud playback.
• RMS Power (4Ω / 2Ω) and Bridged Power: 4 x 150W @ 4Ω; 4 x 230W @ 2Ω; Bridge 2 x 430W @ 4Ω — flexible configurations for diverse speaker needs and system layouts.
• Frequency Response: 20Hz–20kHz, ensuring the amplifier can reproduce the full audible spectrum with fidelity across channels.
• Crossover & Filters: Low Pass 50–250 Hz; High Pass 50–250 Hz; Selectable LPF/FLAT/HPF; X-Over Range 50–250 Hz — precise per-channel tuning for coherent imaging and reduced distortion.
• High-Level Input Compatibility: Allows direct signaling to your radio unit for straightforward integration into existing installs.
• Protection & Indicators: Protection, Clipping, and Power Indicator LEDs alert you to status and limit conditions; supports short circuit, thermal, and voltage protection to safeguard the system.
• Efficiency, Damping, THD: 81% efficiency at 4Ω; 78 damping factor; 0.01% THD — clean power with accurate speaker control.
• Power, Wiring & Physical Specs: 4GA power input; 80A fuse rating; 12GA speaker outputs; 15V operation; matte black finish; 12.25" L x 6.25" W x 3.25" H.
• Cooling & Build Features: Cooling fan included; surface mount component technology supports compact, customizable layouts.

Designed for multi-amp builds or four-speaker setups, the G1800.4D provides four adjustable, full-range channels with configurable crossovers to tailor each speaker’s response. The combination of robust power ratings, protective circuitry, and clear LED indicators helps you achieve a reliable, high-performance install, while the compact, matte-black chassis fits tight spaces and modern dashboards alike.
