Nemesis Audio NA-K200X4D 200W RMS x 4 Class D 4-Channel Car Amplifier Made In Korea Team Series

Nemesis Audio NA-K200X4D is a four‑channel Class D car amplifier from the Team Series (Made in Korea), built for enthusiasts who demand clean, high‑power output with flexible channel configurations. It combines efficient power delivery with comprehensive bass management to suit premium multi‑speaker installs.

• 4-Ohm RMS Power: 200W x 4 — provides substantial, stable power into each 4‑ohm channel for clear, dynamic midrange and vocal clarity.
• 2-Ohm RMS Power: 350W x 4 — supports lower impedance loads for increased headroom and punch on demanding speakers.
• 4-Ohm RMS Bridged Power: 700W x 2 — bridge two channels to drive a mono speaker with up to 700W into a 4‑ohm load, useful for subwoofers or high‑demand transducers in pairs.
• Frequency Response: 10Hz–25kHz — covers deep bass through bright highs for full‑range performance.
• Signal to Noise Ratio: 95dB — low noise floor helps preserve quiet background when music is playing at higher levels.
• Damping Factor: 200dB — indicates strong control of speaker motion for tighter bass articulation.
• Efficiency (4-Ohm, 100Hz): 75% — efficient operation reduces heat and improves power delivery in typical vehicle electrical conditions.
• Input Sensitivity: 6V–0.2V — accommodates a wide range of head units and processors for proper output scaling.
• Subsonic Filter: 10Hz‑500Hz — helps protect speakers from ultra‑low frequencies and improves LFE/sub integration.
• Low Pass Filter: 50Hz‑500Hz — tailors bass output to a sub or low‑frequency speaker, reducing unwanted highs in bass loudness.
• High Pass Filter: 20Hz‑500Hz — blocks very low frequencies on full‑range channels to prevent woofer overexcursion.
• Audiophile Grade Tiffany RCA Input & Output — premium signal path for reduced noise and reliable connectivity.
• 4 Gauge Power & Ground Input — accommodates proper current delivery for premium installations.
• Working Voltage: 10V–16V — designed for typical automotive electrical systems.
• Tested Voltage & THD: 14.4V & Less than 1% — spec confirms clean performance under standard vehicle supply.
• Remote Gain Control with Clipping Indicator — adjust output from the front and monitor for distortion to preserve sound quality.

In a real build, NA-K200X4D excels as a true four‑channel front/rear setup with optional bridging for a dedicated sub or high‑power mono channel. The integrated filters and high SNR create clean, controllable bass and overall clarity, while the premium RCA path and remote gain help maintain signal integrity across the system.
