The NA-400.4D redefines the ratio of power to size. As a Micro Class D amplifier, it provides a clean and powerful signal to four speakers while maintaining a footprint small enough to be hidden behind a dashboard or inside a fairing. It’s the ultimate solution for space-constrained environments that demand high-fidelity sound.
