Alpine MRV-M250 - 1-channel amplifier digital

RV-M250-M - Digital MONO amplifier

Tens of thousands rely on the reliability and high-quality performance of V-Power amplifiers. Now, in their fourth generation, V-Power amplifiers continue this legacy and show that the sound of these amplifiers has never been better than today. Yes, because it is possible to make a good thing even better.
