Nemesis Audio NA-K1000X4D Korean made 4-channel amp. 1700W x4 @2-Ohm / 3600W x2 bridged, with advanced crossover controls.

Nemesis Audio NA-K1000X4D is a Korean-made four-channel Class D amplifier delivering 1700W x4 @ 2-Ohm and 3600W x2 when bridged, built for serious multi-amp car audio setups with solid headroom and efficient cooling.

• 4-channel Class D design: High-efficiency amplification that runs cooler and fits tighter installs while still delivering substantial power to multiple speakers.
• 1700W x4 @ 2-Ohm: Independent per-channel wattage on a 2-ohm load, enabling strong, dynamic performance across four speakers or components.
• Bridged to 3600W x2: Bridge two channels for doubled power to a single speaker pair or sub, increasing bass impact and system flexibility in a compact footprint.
• Subsonic filter: Removes ultra-low frequencies from bass signals to reduce cone excursion, improve control, and protect woofer components in demanding bass passages.
• HPF/LPF crossover controls: Adjustable high-pass and low-pass filters let you tailor each channel’s bandwidth, aiding imaging, clarity, and speaker protection by constraining frequencies within optimal ranges.
• Clipping indicator: Visual feedback of potential distortion, helping you set gains to preserve clarity and avoid audible harshness from overdriven signals.
• Korean-made: Indicates manufacturing origin and build philosophy, aligning with Nemesis Audio’s design and component sourcing expectations.

In a real-world install, this amp supports a multi-voice-coil front stage or a compact four-channel setup while offering bridged power for a dedicated sub/subpair. The integrated subsonic, HPF, and LPF controls provide precise bass shaping and speaker protection, with a clipping indicator that helps tune gains for clean, punchy sound without guesswork.
