DS18 G1000.4D GEN-X Full-Range Class D 4-Channel Amplifier 1000 Watts

The DS18 G1000.4D GEN-X is a 1000W peak, four-channel Full-Range Class D amplifier built for serious car audio systems that demand precise tuning and flexible installation. Its digital (D) topology and adjustable crossovers put professional-grade control in your hands while maintaining efficient, compact performance.

• Amplifier Class: Digital (D) design for efficient, multi-channel power with a slim footprint ideal for tight installs.
• Channels: 4 Channel Full Range, enabling independent front/rear channel amplification or flexible configurations in a single chassis.
• Power Output: 4 x 90W RMS @ 4Ω, 4 x 150W RMS @ 2Ω, and 2 x 300W @ 4Ω (bridged). This gives you clean four-channel performance or the option to bridge two channels for a dedicated sub, depending on impedance.
• Frequency Response: 20Hz–20kHz, ensuring the full audible spectrum is reproduced with consistent level across the amp’s range.
• Signal-to-Noise: >90dB, contributing to a quiet background so micro-details remain clear in busy musical passages.
• Efficiency: 0.92 at 4Ω, indicating low heat generation for a given output level and more usable power in real-world installs.
• Damping Factor: 78, helping control speaker motion for tighter bass and more articulate transients.
• Inputs: High-Level Input Yes; Low Level Input Range 0.25–6 V; Input Impedance 22K. Broad compatibility with factory radios and line-level sources, plus predictable sensitivity for precise tuning.
• Crossover: Selectable LPF/FLAT/HPF with Range 50Hz–2kHz to tailor each channel’s frequency band to your speakers.
• Protection & Indicators: Thermal, Over-Load, DC Output, Short Circuit Output, Voltage Input, Clipping protections; LEDs for Power, Protection, and Clip give instant status feedback.
• Physical: 8.1" L × 4.72" W × 1.96" H; Heatsink length 6.2"; Matte Black finish.
• Power & Build: Power Input Terminal Size 4 GA; Fuse Size 2 × 25A; Surface Mount Component Technology supports precise, reliable construction.
• Weight: 1.2 kg, aiding installation in compact spaces without sacrificing rigidity.

In a typical build, the G1000.4D powers multiple channels with clean, controlled output and flexible crossovers while maintaining safe operation through comprehensive protection and clear status indicators. Its high-level input compatibility and bridge-capable power options make it a versatile choice for enthusiast systems seeking precise tuning and reliable performance in a compact package.
