Prodigy Audio 600 Watt 4 Channel Amplifier | NBM100.4

High-Fidelity Power in a Micro-Chassis Footprint

The Prodigy Audio NBM100.4 is a high-efficiency Class D 4-channel amplifier engineered for enthusiasts who demand audiophile-grade output without sacrificing cabin space. Delivering a conservative 100 Watts RMS per channel at 4 Ohms, this micro-amplifier provides the headroom necessary to drive high-end components or coaxial speakers with surgical precision. Its compact aluminum heat sink is designed for maximum thermal dissipation, allowing for stealth installations under seats, behind dash panels, or in motorcycle fairings where airflow is limited.

Advanced Class D Topology and Signal Integrity

Built on a modern Full-Range Class D architecture, the NBM100.4 achieves over 80% efficiency, significantly reducing current draw on your vehicle's electrical system while minimizing heat output. The internal circuitry features high-grade capacitors and shielded inductors to maintain a high Signal-to-Noise ratio, ensuring that your music remains transparent and free of floor noise. With a frequency response spanning 20Hz to 20kHz, this amplifier captures the full spectrum of your recordings, from the snap of a snare to the shimmer of a cymbal.

Precision Tuning for Integrated Systems

Integration flexibility is at the heart of the NBM series. The NBM100.4 features fully adjustable High-Pass and Low-Pass crossovers (40Hz - 400Hz), allowing you to perfectly phase-link your door speakers with your subwoofer system. Whether you are running a traditional 4-channel setup or bridging the rear channels to power a small subwoofer at 300 Watts @ 4 Ohms, the NBM100.4 provides the versatility required for complex system builds. Its 4-way protection circuitry (Thermal, Voltage, Short, and Offset) ensures that your investment stays protected even under demanding playback conditions.
