Raising the Bar

The new V-Power products are now Class D digital amplifiers, resulting in a huge efficiency gain versus their predecessors without draining your battery or your pockets. Class-D provides continuous clean power to your speakers, operating at 80% efficiency far greater than conventional Class A or B amplifiers. Translation: Enjoy cleaner bass, even during extreme power demands.

Big Power, Small Package

V-Power amplifiers are known for their compact size, but don’t underestimate their power capacity. Although they have a 40% smaller footprint than their predecessors, they produce the same amount of power as before. Get the power you need, even if you have limited installation space.

Keep the Music Playing

The V-Power amplifiers provide reliable, stable thermal performance. They use a new, higher efficiency design to achieve non-stop music playback. A new circuit and heat sink design allows gradual thermal absorption and provides a gentle, almost undetectable power control.

Dual Feedback Modulation

Dual internal error correction technology – which had previously only been available in the PDX and X-Power amplifiers, is now integrated in V-Power mono amplifiers. The audio input signal is analyzed, compared, and corrected twice dynamically as the signal is processed through the amplifier. The result is amplifiers with the widest frequency response, higher damping factor, and lowest noise in its class.

Exceptionally Simple Sound Upgrade

The V-Power's 4-channel speaker level inputs connect directly to any head unit, without the need for external converters. This makes the V-Power amplifiers ideal for upgrading factory and aftermarket systems. The flush mount controls make for easy installation. The terminal covers conveniently snap-on without the need for additional tools, to protect the wiring connections while creating a clean, finished appearance.

Proven Power

Each V-Power amplifier comes with its very own birth-sheet. V-Power amplifiers are tested and documented to show their true actual output.

Remote Bass Level Adjustment

Remote Control Bass Knob

The MRV-M500 and MRV-M250 mono models are compatible with the RUX-KNOB remote bass knob (sold separately). Use the RUX-KNOB to conveniently adjust bass levels from your dash.
