DS18 GEN-X G3600.4D Full-Range Class-D 4-Channel Amplifier

High-Efficiency 3600W Peak Full-Range Class D 4-Channel Car Audio Amplifier with Precision Crossovers and Multi-Stage Protection

The DS18 G3600.4D GEN-X is a compact, high-output 4-channel full-range Class D car audio amplifier designed to power multi-speaker arrays and subwoofers with exceptional clarity and efficiency. Delivering up to 300 Watts RMS per channel at 4 Ohms and bridgeable to 740 Watts RMS across two channels, it provides versatile power configurations within a space-saving chassis. Engineered with selectable high-pass and low-pass crossover filters alongside multi-stage protection indicators, it offers reliable, distortion-free audio performance for demanding mobile sound systems.

• High-Efficiency Digital Class D Topology: Produces immense acoustic output with minimal thermal dissipation and low current draw, allowing easy installation in compact vehicle compartments.
• Versatile 4-Channel & Bridged Power: Delivers 4 x 300W RMS at 4 Ohms, 4 x 420W RMS at 2 Ohms, or 2 x 740W RMS bridged at 4 Ohms to drive full-range component speakers or subwoofers.
• Selectable Multi-Mode Crossovers: Features independent front and rear 3-position crossover switches (HPF / FULL / LPF) with variable 50Hz–250Hz frequency adjustment to tailor sound curves accurately.
• Comprehensive Multi-Stage Protection: Safeguards your audio system with built-in thermal, overload, short-circuit, DC output, and voltage input protection circuitry.
• Visual Diagnostic & Clipping LED Indicators: Outfitted with dedicated diagnostic LEDs for Power, Protection, and Clipping to help eliminate harmonic distortion and prevent speaker damage during setup.
