DS18 EXL-P4000X1D EXL Power 1-Channel Class D Amplifier 4000 x 1 @ 1-Ohm Watts Rms Made In Korea

DS18 EXL-P4000X1D is a 1-channel Class D car amplifier delivering 4000W RMS at 1Ω, built in Korea for demanding subwoofer systems. Its optimized Korean circuitry, robust heatsink, and thermal protection maintain consistent performance under demanding bass passages.

• RMS Power @ 1 Ohm: 4000W x 1 CH — continuous, high-current power ideal for deep, authoritative bass in a dedicated subwoofer setup.
• Channel / Class: 1-Channel Monoblock Class D — single-channel design optimized for subwoofers with high efficiency and heat management.
• Minimum Impedance: 1 Ohm — supports very low-impedance subs for maximum output while maintaining stability.
• Frequency Response: 15Hz–250Hz — extends into ultrabass ranges, giving you flexibility to tailor the low end.
• Signal-to-Noise Ratio: >98dB — ensures a very low noise floor so bass remains clean even at high output.
• Efficiency @ 4 Ohm: >87% — high efficiency reduces heat buildup during sustained bass playback.
• THD: <0.02% — extremely low total harmonic distortion for tight, accurate bass reproduction.
• Inputs / Wiring: 1/0 AWG power/ground inputs and 8 AWG speaker terminals — designed for minimal voltage drop and solid high-current connections.
• bass boost / filters: Bass Boost 0–+9dB (30–60 Hz); Infrasonic Filter 10–30 Hz; LPF is fixed with a selectable range (35–250 Hz) — gives you precise control over the bass spectrum and protection against subsonic signals.
• Remote Level Control: Dash-mount remote level control — adjust bass level from the cockpit to match your listening position.
• Protection & Safety: Thermal Protection (>75°C / 167°F); Over-Load, DC Output, Short Circuit Output, Voltage Input (>15.5V); Clipping Protection — guards against common fault conditions during hard play.
• Fuse / Power Input: 450 A inline fuse recommended; Power Input Size 0 AWG — aligns with high-current installation practices.
• Physical: Black Aluminum enclosure; Dimensions 17.4 x 8.77 x 2.67 inches — a compact, rugged chassis designed for performance-focused builds.
• Made In: Korea — engineered and manufactured in Korea with premium components.

Benefits: The EXL-P4000X1D is built for high-demand monoblock subs, delivering serious 1Ω power while maintaining efficiency and thermal stability. Its robust wiring, 450 A fuse recommendation, and protective features help sustain loud, low-distortion bass in premium installations. Fixed LPF with adjustable sub-bass tuning, bass boost, and infrasonic filtering allow precise shaping of the low end, while dash-mount remote control enables on-the-fly level matching to the rest of your system.
