Evolution of Class-D digital platform

Certificate of Achievement
Each V-Power amplifier is supplied with its own Certificate of Achievement. V-Power amplifiers are tested and certified, so you can read the actual output power.
The new V-Power amplifiers are Class D digital amplifier, which leads to a huge gain in efficiency over their predecessors. And all this without draining your battery or your wallet unötig. Class-D provides continuous power, which is at 80% efficiency far greater than conventional Class-A or Class-B amplifiers. This bedeudet Enjoy clean bass, even during extreme performance requirements.

Big performance, small size
V-Power amplifiers are known for their compact size, but not to be underestimated in their performance. Although they have a 40% smaller footprint than their predecessors, they produce the same output as before. Get the power you need, even if you have only a very limited mounting space.
Intelligent design for uninterrupted operation
Even if you properly treat your music for a long time run, this amp does not turn off simple. The integrated temperature management circuitry ensures that the temperature level never goes into the red zone. No distortion, no interruptions!

Signal difference modulation
Two internal error correction technologies - which were previously only in the X-PDX and power amplifiers are available, is now integrated into V-mono Power amplifier. The audio input signal in this case we analyzed, compared and corrected dynamically twice, when the signal is processed by the amplifier. The result is a wider frequency response, a higher damping factor and lowest noise in its class.
Easy upgrade of all systems
The V-Power 4-channel speaker level inputs of these amplifiers can be connected without pre-outs directly to any factory ECU. This allows you to upgrade your original system with more power and better speakers.
The flush-mounted ports provide an easy and secure installation.

Bass Remote
The MRV MRV-M500 and M250 mono amplifier are compatible with the RUX-KNOB remote bass (sold separately). The RUX-KNOB (sold separately) enables the complete control of the bass adjustment from the dashboard.
