Musway M6v4-512K

The Musway M6v4-512K combines a powerful 6-channel Class D amplifier with a highly customizable 8-channel digital sound processor (DSP). The fourth generation of the popular Musway amplifier impresses with high output power, outstanding sound quality, and numerous options for custom sound optimization.

In the trade magazine *Car & Hifi* (01/2025), the M6v4 was named “BEST PRODUCT” and selected as “PRODUCT OF THE YEAR 2025” in the DSP power amplifier category. In lab testing, the amplifier achieved an impressive 6 × 96 watts at 4 ohms and 6 × 166 watts at 2 ohms.

Thanks to its advanced 512K DSP technology, the device offers additional adjustment options, including a 10-band input equalizer as well as high-shelf, low-shelf, and all-pass filters. High-quality Burr-Brown signal converters and an Analog Devices DSP ensure precise digital signal processing.

The Musway DSP software allows you to individually configure crossovers, time alignment, equalizers, phase, and other sound parameters. The included 2.5-meter MX-Connect ISO wiring harness enables easy integration into a wide range of vehicles. Vehicle-specific plug-and-play adapters are available as an option.
