DS18 ION1200.1D Compact Full-Range Class D 1-Channel Amplifier 1200 Watts RMS

DS18 ION1200.1D is a compact, full-range monoblock Class D amplifier delivering 1200W RMS at 1Ω, engineered for tight automotive installations with high efficiency and flexible tone-shaping options. Its micro digital design and surface-mount construction let you place it almost anywhere in your build while keeping performance punchy and precise.

• 1-Channel Monoblock Class D: A single high-current output optimized for demanding mono applications, providing clean power with efficiency in a small footprint.
• RMS Power: 1200W @ 1Ω, 800W @ 2Ω, 400W @ 4Ω — gives you scalable headroom for a single driver or driven sub, depending on your impedance and crossover setup.
• Total Watts (Peak): 3600W — peak capability for dynamic transients without folding into distortion.
• Frequency Response: 10Hz–20kHz — supports full-range signal, from deep bass to crisp highs, with a single-channel design.
• Selectable Crossover: Full-range with HP: 15Hz–1kHz and LP: 40Hz–20kHz — tailor the spectrum to bass-focused, midrange, or full-range applications.
• Bass Boost: 0–12dB at 45Hz — add controlled bass emphasis to match your enclosure and musical style.
• Inputs & Terminals: Hi-Level inputs and Tiffany RCA terminals; remote level control for on-dash adjustment — flexible integration with factory radios and aftermarket head units alike.
• Protection & Indicators: Power, Protect, and Clipping LEDs; short circuit, thermal, DC offset, high/low voltage, and clipping protections — keeps you informed and safeguarded during tunes.
• Efficiency & Build: 88% efficiency at 4Ω; protective PCB coating; bonded components for vibration protection — designed for reliability in automotive environments.
• Physical & Power: 6.92" L x 4.72" W x 2" H; heatsink 5.62"; 4 AWG power input; external 100A fuse; aluminum chassis (Black/Silver) — compact yet capable for constrained spaces.
• Cooling: No cooling fan — designed for quiet operation in the vehicle interior.

In a car audio build, the ION1200.1D suits a compact, high-output mono path where you want to drive a sub or a dedicated full-range speaker with flexible tone shaping. The Hi-Level inputs simplify integration with non-RCA factory radios, while the adjustable crossover and remote level control let you dial in the exact balance between bass and mids/highs. Protective features and robust electrical protection provide reliable operation under varying vehicle conditions, all in a small, vibration-aware package that won’t dominate your install space.
