DS18 FRP-5K/TI FRP Compact Full-Range Class D 1-Channel Amplifier 5,000 Watts Rms @ 1-Ohm Titanium

DS18 FRP Compact Full-Range Class D monoblock amplifier packs 3,500W RMS into a 1Ω load in a remarkably small chassis, engineered for demanding car audio builds where space is at a premium and efficiency matters. It uses a compact, full-range design with adjustable crossovers to tailor bass, mids, or highs to your speaker configuration.

• RMS Power @ 4 ohms: 1,000W — stable, clean output at higher impedance, suitable for single-channel tasks with modest sensitivity systems.
• RMS Power @ 2 ohms: 2,000W — higher current capability for more dynamic, louder bass or full-range demands in multi-driver setups.
• RMS Power @ 1 ohm: 3,500W — maximum sustained power at the lowest impedance, ideal for high-demand sub or full-range mono applications; Burst up to 4,000W handles transient peaks.
• Frequency Response: 10Hz–20kHz — covers deep sub-bass through highs, ensuring a wide tonal window for a full-range signal.
• Signal to Noise Ratio: 83dB — lower noise floor for clearer, quieter operation with your source material.
• Efficiency @ 4 ohms: 80.9% — higher efficiency reduces heat and battery draw in normal operating conditions.
• Damping Factor: 90 — helps control speaker cone movement for tighter bass under dynamic transients.
• Input Impedance: 10KΩ — compatible with typical head-unit and preamp outputs.
• Total Harmonic Distortion (THD): 0.5% — low distortion contributing to cleaner sound across the band.
• Low Level Input Range: 400mV–3.6V — broad compatibility with common line-level signals.
• High Level Input: No — accepts only low-level inputs as configured.
• X-Over: Fixed Band-Pass — internal crossover path arranged for band-limited operation when used in full-range configurations.
• X-Over Range: HP 10Hz–2kHz / LP 40Hz–20kHz — selectable high-pass and low-pass boundaries for shaping the output to your speaker lineup.
• Bass Boost: 0–12dB @ 50Hz — adjustable low-end lift to tighten or extend bass response with control over presence at low frequencies.
• Bass Boost Frequency: 50Hz — targeted boost region to emphasize sub-bass performance.
• Amplifier Class: Digital — designed for efficient, compact power delivery with solid-state reliability.
• Number of Channels: 1CH — monoblock configuration for dedicated single-channel power.
• Minimum Impedance: 1Ω — stable operation into 1-ohm loads for aggressive low-impedance setups.
• Remote Level Control: Yes (clip indicator included); Voltmeter Optional — convenient on-vehicle level adjustment with visible status, voltmeter option available for monitoring.
• Cooling: Yes (Smart Cooling x 2) — dual fans provide active thermal management for sustained high-output operation.
• Tiffany RCA Terminal: Yes — high-quality, durable input/output connections.
• LED Indicators: Power / Protect / Clipping — real-time status feedback for quick diagnostics in dash or trunk installations.
• Body Color / Finish: Blue / Red / Titanium — color options to match or complement your install aesthetic.
• Compact Size: Yes — designed for easy installation in tight spaces behind dashboards or in trunks/footwells.
• PCB & Construction: Four-Layer Traces PCB Design; Surface Mount Component Technology; Protective PCB coating resists moisture; Bonded components provide extra vibration protection — built for durability in challenging road conditions.
• Protection: Thermal, Over-Load, DC Output, Short Circuit Output, Voltage Input, Clipping — comprehensive safeguards to protect both the amplifier and the vehicle electrical system.

In a real-world build, this amplifier excels as a compact, single-channel heart for a bass-heavy sub setup or a full-range mono path in a multi-amp system. It combines high peak and sustained power with protective features and a slim footprint, making it a solid choice when space is at a premium but performance cannot be compromised.
