GZHA MINI TWO

The Ground Zero GZHA MINI TWO is an exceptionally compact 2-channel amplifier from the Hydrogen series that combines high output power with a small footprint. Thanks to efficient Class D technology, this amplifier is ideal for high-power front or rear systems and can also drive a subwoofer in bridged mode.

Despite its compact dimensions of just 135 x 52 x 210 mm, the GZHA MINI TWO delivers up to 2 x 230 watts RMS into 2 ohms. In bridge mode, it delivers 460 watts RMS into 4 ohms. This means the power amplifier offers sufficient power reserves for demanding car audio installations without taking up an unnecessary amount of installation space.

The built-in active crossover allows for flexible adjustment to the connected speaker system. High-pass, low-pass, and band-pass filters can be adjusted over a wide range. A bass boost function is also available. Using the included remote control, the output level can be conveniently adjusted from the driver's seat.

For integration into modern vehicles, the GZHA MINI TWO features a high-level input in addition to the standard RCA input. The Auto-On function allows the amplifier to turn on automatically when a speaker signal is present—which is particularly useful when retrofitting factory-installed radios and OEM audio systems.
