The new M4v3+ DSP amplifier can be seen as the little brother of the M6 ​​model. The M4+ serves four speakers but offers more power per channel than the larger M6. Both models also share the very compact housing dimensions, made possible by the ingeniously designed 4-fold laminated circuit board.

The newly designed Class D technology is particularly immune to EMC interference, which is essential for trouble-free music enjoyment in modern vehicles crammed with electronic components. With four bridgeable power outputs, each with 135 watts RMS per channel (at 2 Ω), the M4+ offers a convincing output power with a total of 540 watts RMS.

With the enclosed wiring harness including ISO plug and optionally available Plug+Play cable sets, the M4+ is perfect for tuning 4-channel sound systems ex works. Thanks to four additional preamplifier outputs that can be set via DSP, it is also possible to integrate additional amplifiers. Last but not least, the M4+v3 amp also has a high-level input with error protection system for interference-free connection to OEM factory radios.
