The new M4+v3 DSP amplifier can be considered as the little brother of the M6 model. The only difference: The M4+ is coming with four amplified speakers, but still offering more power per channel than the larger M6. The newly engineered Class D technology is particularly immune to EMC interference, which is virtually indispensable in today‘s electronic-packed vehicles.  A key-premise to enjoy interference-free music while driving. With four bridged power outputs, each one providing 135 watts RMS per channel (2 Ω), the M4+v3 offers remarkable output power with a total of 540 watts RMS. M4 + is perfect for tuning original 4-channel sound systems. Four additional DSP-tunable preamp outputs allow the integration of further amplifiers.
