HiFonics MERCURY I V2

The HiFonics MERCURY series has been impressing users for years with its combination of compact design, high output power, and extensive features. With the MERCURY I V2, HiFonics offers a powerful digital mono amplifier designed specifically to drive high-output subwoofers.

Thanks to modern Class D technology, the MERCURY I V2 achieves an efficiency of up to 85% and, despite its compact dimensions, delivers an output power of up to 750 watts RMS into 1 ohm. This makes the amplifier suitable for both single high-power subwoofers and corresponding multi-subwoofer configurations.

Features include a continuously adjustable low-pass filter, a subsonic filter, an adjustable bass boost, and a phase control. The included wired bass level remote control allows you to conveniently adjust the bass volume from the driver's seat.

The built-in high-level inputs with EPS® (Error Protection System) also allow for integration into existing factory-installed sound systems. An automatic power-on function via the high-level inputs makes retrofitting easier.

A solid aluminum heat sink ensures reliable heat dissipation. High-quality cast end caps with concealed mounting channels and protected connection areas round out the design.
