DS18 FRP-2.5K/RD FRP Compact Full-Range Class D 1-Channel Amplifier 2,500 Watts Rms @ 1-Ohm RED

Delivering 2,500W RMS at 1Ω in a compact, full-range Class D monoblock, the DS18 FRP-2.5K is built for high-output systems where space is at a premium. Its micro digital design, rugged PCB coating, and vibration-protected construction keep performance consistent in harsh automotive environments.

• RMS Power Output (4/2/1Ω): 700W @ 4Ω; 1300W @ 2Ω; 2500W @ 1Ω; 2800W @ 1Ω (Burst). This gives you scalable power for different speaker loads and the ability to push peak transients when the demand is highest.
• Frequency Response: 10Hz–20kHz. Reproduces deep sub-bass through crisp highs, enabling a true full-range signal from a single channel.
• Efficiency: 85.6% @ 4Ω. High efficiency reduces heat under typical listening levels, improving reliability in compact installations.
• Signal-to-Noise Ratio: 83dB. Indicates a low noise floor, preserving dynamic detail as you raise levels.
• Bass Boost: 0–12dB at 50Hz. Adds controlled low-end emphasis for more punch without resorting to external EQ tweaks.
• Crossover / Filter: Fixed Band-Pass crossover; HP 10Hz–2kHz; LP 40Hz–20kHz. Internal filtering provides defined sonic separation without external components.
• Inputs & Terminals: Tiffany RCA Terminal; Input Impedance 10kΩ; Low Level Input Range 400mV–3.6V; High Level Input: Not available. These specs define the signal compatibility and how it integrates with your head unit.
• Protection & Indicators: Thermal, Over-Load, DC Output, Short Circuit Output, Voltage Input, and Clipping protections; LED indicators for Power / Protect / Clipping; Remote Level Control with Clip Indicator (Voltmeter Optional). Built-in safeguards keep the system level and safe under demanding operation.
• Cooling: Smart Cooling x 2 (two fans). Active cooling helps maintain performance during long sessions or high-demand builds.
• Build & Finish: Four-layer PCB design; Surface Mount Component Technology; Protective coating for moisture resistance and vibration protection; Tiffany RCA Terminal. Durable construction designed for long-term reliability.
• Physical & Color Options: Overall 8.85" L × 5.5" W × 2.36" H; Heatsink 7.6" long; Weight 2.1kg; color options blue / titanium / red. Compact footprint with aesthetic choices to suit your install.
• Connectivity: 0GA input terminal; Fuse Size (Recommended) 200A. Ready for high-current power delivery with appropriate protection in mind.

The FRP-2.5K is ideal for single-channel, high‑power needs in tight compartments, providing substantial output, robust protection, and flexible mounting in three color options. Its fixed bandwidth, bass-boost capability, and compact footprint make it a practical centerpiece for aggressive full‑range or bass‑heavy builds while maintaining installation simplicity.
