DS18 FRP-3.5K/RD FRP Compact Full-Range Class D 1-Channel Amplifier 3,500 Watts Rms @ 1-Ohm RED

DS18 FRP-3.5K/RD is a compact full-range digital monoblock amplifier delivering 3,500W RMS at 1 ohm, built for high‑power car audio where space is at a premium. Available in blue, titanium, or red, it combines aggressive power with DS18’s rugged construction for road-ready performance.

• 1-Channel Full-Range Monoblock: a single-channel design capable of full-range output; band-pass adjustments let you tailor the amp for bass, mids, or highs depending on your installation goals.
• Power Output (RMS / Burst): 1000W RMS @ 4 ohms, 2000W RMS @ 2 ohms, 3500W RMS @ 1 ohm, 4000W RMS @ 1 ohm (BURST); provides scalable headroom for demanding systems.
• Efficiency: 80.9% efficiency at 4 ohms, contributing to lower heat when running at moderate loads and improving overall system performance.
• Fixed Band-Pass Crossover: no selectable crossover; HP 10Hz–2kHz and LP 40Hz–20kHz ranges enable targeted shaping within a fixed band-pass configuration.
• Protection & Indicators: power, protection, and clipping LEDs give real-time status; protections include thermal, over-load, DC offset, and voltage safeguards for the amp and vehicle.
• Build & Durability: surface-mount components on a four-layer PCB with moisture-resistant coating and bonded components for vibration resistance in harsh conditions.
• Inputs & Connectivity: Tiffany RCA terminals, 0GA power input, and remote level control options (volmeter optional); 10KΩ input impedance and low-level input range 400mV–3.6V.
• Cooling & Accessories: smart dual cooling fans to manage thermal performance; includes clip indicator and optional voltmeter on the remote control.
• Size & Finish: compact size designed for easy installation and color options (blue, titanium, red) to match your system aesthetics.

Benefits: In a single-amped setup, FRP-3.5K/RD supports high‑power applications with a fixed crossover that lets you push bass, mids, or highs from a single chassis. The 1-ohm capability and multiple RMS ratings provide scalable power for aggressive subwoofers or full-range voicings, while the dual‑fan cooling, moisture‑resistant PCB coating, and vibration‑suppressing construction enhance reliability under road conditions. Tiffany RCA terminals, 0GA power input, and a robust protection suite give you clear, real-world assurance during installation and daily driving.
