Musway M4+V3-512K

The Musway M4+V3 512K is a compact and powerful 4-channel Class-D amplifier with an integrated 8-channel DSP, making it ideal for high-quality upgrades to factory-installed sound systems. With up to 4 x 135 watts RMS at 2 ohms, it offers ample power reserves for demanding speaker systems and, thanks to its four additional DSP-controlled RCA outputs, allows for the integration of additional amplifiers.

Modern Class-D technology ensures high efficiency and low electromagnetic interference. The integrated 512K DSP, featuring Burr-Brown converters and an Analog Devices signal processor, enables precise sound tuning via the Musway DSP software or a compatible smartphone app with an optional Bluetooth module.

Thanks to the intelligent high-level input with EPS® (Error Protection System), the automatic power-on function, and the included MX-Connect™ ISO wiring harness, the amplifier can be integrated into existing vehicle systems with ease. Its compact design also allows for space-saving installation.
