Unleash powerful, precise sound with the Nemesis Audio NA-3KM

The NA-3KM is built for enthusiasts who demand control, durability, and serious bass without sacrificing detail. This 1-channel monoblock amplifier delivers high-power output in a compact footprint, allowing you to elevate your car audio system with a clean, confident performance across a wide range of listening styles.

Power and precision you can feel

Engineered for flexibility, the NA-3KM exposes multiple load scenarios so you can tailor your setup for the subwoofer you love. At 4 ohms, it provides solid RMS and peak figures; at 2 ohms, it pushes harder; and at 1 ohm, it unleashes the maximum headroom the design can offer. This range helps balance volume, bass impact, and electrical stability in real-world driving conditions.

  • RMS / MAX @ 4 Ohm: 600W / 1200W
  • RMS / MAX @ 2 Ohm: 950W / 1900W
  • RMS / MAX @ 1 Ohm: 1500W / 3000W

Quality signals, reliable performance

With a measured clarity and robust protection, the NA-3KM aims to preserve musical detail even when the volume climbs. The combination of a wide frequency range, controlled bass shaping, and a capable SNR contributes to a listening experience where bass sits firm, clean, and responsive under dynamic changes in music and road conditions.

Compact footprint, flexible installation

Measuring 341 × 185 × 55 mm and weighing about 7 lbs, this amplifier is designed for versatile mounting in a vehicle. Its low-level input (0.2–5 V) makes integration with most head units straightforward while leaving room for processors and additional gear in your audio chain.

Real-world use cases you might explore

Expect tighter bass control and reduced distortion at high output when pairing with capable subwoofers. The NA-3KM is suited for enthusiasts who want a loud, clean bass response without compromising system compatibility or reliability. It invites you to experiment with sequencing, crossover settings, and tuning that suit your vehicle’s acoustics and music tastes.

Note: Benefits described are based on the listed specifications and typical use scenarios. Individual results depend on your subwoofer, enclosure, head unit, and vehicle acoustics.
