Nemesis Audio NA-K2200.5D 2200W 5-Channel Class D Monoblock Car Amplifier Made In Korea Team Series

Made in Korea, the Nemesis Audio NA-K2200.5D delivers 2200W across five channels in a Class D design. Built for serious multi-amp setups, it provides four full-range channels plus a high-current sub channel in the Team Series.

• 4-Ohm RMS Power: 125W x4 + 600W x1. This means four front/rear channels each deliver solid mid/high power, while the fifth channel drives a sub with a substantial wattage reserve.
• 2-Ohm RMS Power: 190W x4 + 1100W x1. Lower impedance on the front channels increases available output, with a dramatic power boost on the sub channel for deeper bass.
• 1-Ohm RMS Power: 1500W x1. This channel provides peak subwoofer amplification, suitable for demanding low-end performance when wired for 1-ohm operation.
• 4-Ohm RMS Bridged Power: 380W x2 + 600W x1. Bridging combines channels for higher single-channel output, useful for targeted bass applications or pair-matching a sub with existing channels.
• Frequency Response: CH1-4 10Hz–30kHz; CH5 10Hz–250Hz. Full-range front channels cover the audible spectrum, while CH5 is tailored for low-frequency bass essential for sub-systems.
• Signal to Noise Ratio: 95dB. Higher SNR reduces background hiss and improves clarity in quiet passages and precise transients.
• Damping Factor: 200. Higher damping helps control speaker cone movement for tighter bass and more authoritative transients.
• Efficiency: 75% (4-Ohm, 100Hz) for CH1-4; 90% for CH5. Efficiency relates to heat generation and power delivery under typical operating conditions, with the sub channel optimized for high output.
• Input Sensitivity: 6V–0.2V. A broad input range allows compatibility with various head units and preamp levels without excessive gain errors.
• Subsonic Filter: 10Hz–50Hz @ 24dB/Oct. This filter helps manage ultra-low frequencies, potentially reducing unnecessary woofer excursion and protecting drivers.
• Bass Boost: 0–9dB @ 45Hz. Adjustable bass emphasis at the tuned frequency gives you system-wide depth without altering the overall tonal balance.
• Low Pass Filter: CH1-4 50Hz–5KHz; CH5 35Hz–250Hz. Crossover control shapes where each channel reproduces frequencies, enabling clean separation between bass, mids, and highs.
• High Pass Filter: 20Hz–5KHz. Allows you to set a high-pass crossover to protect ultra-low frequencies from content you don’t want on certain channels.
• Audiophile Grade Tiffany RCA Input & Output: Premium signal connections for low-noise preamp signal transfer and reliable power delivery to the amp.
• 0 Gauge Power & Ground Input: Heavy-gauge wiring capable of handling high current demands with minimal resistance, supporting stable operation at high output.
• Working Voltage: 10V–16V. Designed to operate within typical vehicle electrical systems, including fluctuations during operation.
• Tested Voltage & THD: 14.4V & Less than 1% THD. Indicates low total harmonic distortion under standard supply conditions for clean signal reproduction.
• Remote Gain Control with Clipping Indicator: Allows on-dash adjustment of output and provides a visual cue when the signal is nearing clipping for system protection.
• Protection: 4 Way Protection Circuits (Thermal, High & Low Voltage, Short & DC). Built-in safeguards help prevent damage from common in-vehicle stressors and abnormal conditions.
• Dimensions (LxWxH): 450x220x68mm. Provides a clear sense of space required for installation in trunk, under-seat, or similarly sized compartments.

The NA-K2200.5D is designed for a multi-amp front stage with a dedicated sub channel, offering flexible impedance options, precise crossover control, and robust protection to support high-performance car audio builds without compromising reliability.
