Musway FOUR200

The Musway FOUR200, part of the new 2026 MX model generation, combines outstanding sound quality, high power reserves, and premium build quality in a compact enclosure. With a powerful 4 x 200 watts RMS at 2 ohms, this digital 4-channel amplifier delivers ample power for demanding car audio systems and high-performance speaker configurations.

Thanks to the innovative Dynamic Headroom Technology (DHR), up to 235 watts RMS per channel is available in partial active mode under suitable conditions. The optimized high-level inputs with EPS® handle input signals up to 20 volts and allow for easy integration into existing in-car audio systems. Comprehensive active crossovers, a bandpass function, and an adjustable bass boost offer numerous options for custom sound tuning.

The FOUR200 also impresses visually with a high-quality anodized aluminum heat sink, elegant aluminum end panels, and an illuminated real-glass logo. Thanks to its efficient Class D technology and compact dimensions, the amplifier is particularly well-suited for space-saving installations. When combined with Musway DSP amplifiers such as the M4+ or M6, as well as the DSP68, it enables the creation of powerful and flexibly configurable high-end sound systems.
