Nemesis Audio NA-K4000D 4000W RMS @ 1-Ohm Class D 1-Channel Monoblock Car Amplifier Made In Korea Team Series

The Nemesis Audio NA-K4000D is a 1-channel Class D monoblock amplifier delivering 4000W RMS at 1 Ohm, Made in Korea as part of the Team Series for serious sub-bass builds. It’s engineered for extreme headroom in a single-channel subwoofer setup with high-current capability.

• 1-Ohm RMS Power: 4,000W RMS output, giving maximum thrust to a properly matched subwoofer for the deepest, most articulate bass at low impedance.
• 2-Ohm RMS Power: 2,400W RMS output, blending high-output capability with increased stability for demanding subloads.
• 4-Ohm RMS Power: 1,200W RMS output, useful for steady, efficient operation with compatible subs.
• 2-Ohm Strappable Power: 8,000W, enabling higher total system power when using paired units in strap configurations.
• Frequency Response: 10Hz–250Hz, extended low-end reach that covers deep sub-bass while remaining responsive through upper bass.
• Signal to Noise Ratio: 95dB, indicating a quiet baseline which helps preserve dynamic range under heavy output.
• Damping Factor: 400dB, reflecting strong control over woofer motion for tight, controlled bass.
• Efficiency (4-Ohm 100Hz): 90%, meaning less heat generation at the tested condition and better overall efficiency in your install.
• Input Sensitivity: 6V–0.2V, a wide range that accommodates various head-unit outputs and source signals for full-scale power.
• Subsonic Filter: 10Hz–50Hz @ 24dB/Oct, allowing you to roll off ultra-low frequencies player-wide to protect subs and maximize daily driving reliability.
• Bass Boost: 0–9dB @ 45Hz, enabling targeted bass lift without muddying the overall response.
• Low Pass Filter: 35Hz–250Hz @ 24dB, giving precise top-end shaping to keep the amp focused on the fundamental sub ranges.
• Strappable Connection: 0 Gauge Power & Ground Input, designed for high-current installations and inter-unit strap configurations.
• Working Voltage: 10V–16V, compatible with typical automotive electrical systems for stable operation under varying charging conditions.

In a high-performance subwoofer build, NA-K4000D delivers significant headroom for a single, large enclosure or multi-amp configurations via strap options. The combination of a wide frequency range, tunable filters, and high-current capability enables precise bass control with minimal noise and heat in demanding installations.
