New HYDROGEN MINI amplifiers –
Unexpected performance and power, wrapped in a noble space-saving housing


Due to the environment of modern cars, the installation space is very limited; therefore,
there is a special need for space-saving amplifiers. Hence, Ground Zero created a line of class D amplifiers delivering outstanding performance but still remaining very small-sized.


…and that´s why they are called: “MINI”!


Each of the HYDROGEN series MINI amplifiers got an identical, black-anodized aluminum heat sink with engraved Ground Zero logo and model number with modest outer dimensions of just 135 x 52 x 210 mm / 5.32 x 2.05 x 8.27”


The two and four channel fullrange class D amplifiers feature subsonic, high pass, low pass or bandpass filter configuration and high level inputs with auto-on function. In addition there is a bass remote included with the two channel model and the mono. Furthermore, the mono version contains phase shift control and link mode option to a second unit.
