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.
Non Shut-Down Design
Even if you pound your music for a long time, these amps won’t shut down. They use a Thermal Management Processor to make sure the heat level never gets too high. No distortion, no interruptions!
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 analysed, 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.
Each V-Power amplifier comes with its very own birth-sheet. V-Power amplifiers are tested and documented to show their true actual output.
