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

DS18 FRP-3.5K/BL is a compact full-range monoblock Class D amplifier delivering 3,500W RMS at 1Ω, built for high-power car audio installs where space is at a premium.

• RMS Power at 4/2/1 ohms: 1000W @ 4Ω, 2000W @ 2Ω, 3500W @ 1Ω; Burst 4000W @ 1Ω. In real-world use this means the amp maintains strong, consistent output as the speaker load changes, with peak capability for transients.
• Amp Type and Channel: Digital Class D, Full-Range Monoblock; 1 channel. Designed to deliver high efficiency in a compact package with a single high-current output for demanding loads.
• Bandwidth and Clarity: Frequency response 10Hz–20kHz; THD 0.5%; SNR 83dB. Wide frequency coverage supports deep bass to crisp highs while keeping distortion low for cleaner sound.
• Efficiency: 80.9% at 4Ω. Higher efficiency reduces heat under typical playing conditions, aiding reliability in sealed and vented enclosures alike.
• Crossover and Inputs: Fixed band-pass with HP 10Hz–2kHz and LP 40Hz–20kHz; Low Level Input 400mV–3.6V; High Level Input No selectable. Provides predefined frequency shaping to suit different speaker placements and system goals without complex wiring.
• Bass and Tone shaping: Bass Boost 0–12dB at 50Hz. Adds controlled low-end emphasis when needed to fill out bass response in smaller or acoustically challenging cars.
• Protections and Indicators: Power, Protect, and Clipping LED indicators; Thermal, Over-Load, DC Output, Short Circuit Output, Voltage Input, and Clipping protections. Real-time status helps safeguard the amplifier and vehicle electrical system.
• Cooling and Durability: Dual smart cooling fans; protective PCB coating against moisture; bonded components for vibration protection; four-layer trace PCB design; surface-mount components. Built to endure road conditions and vibration while maintaining performance.
• Connectivity and Build: Tiffany RCA terminals; remote level control with clip indicator included (voltmeter option available); compact size for easy installation; body colors Blue, Red, or Titanium.

Benefits: In a real car audio build, FRP-3.5K/BL serves as a high-current power source capable of driving demanding loads with precision. The 1Ω capability and 3.5kW RMS rating enable robust bass response and clean mids/highs when the band-pass is set for Bass, Mids, or Highs. The included clip indicator and option for a voltmeter facilitate tuning and protection, while dual fans and a moisture-resistant PCB design protect reliability in harsh environments. Its compact footprint and multiple color finishes help it fit into tight spaces and match your system aesthetic.
