NEW GROUND ZERO Amplifiers
IRIDIUM Series Speaker Amplifiers
The entire line of IRIDIUM series amplifiers has been revised in detail. In addition to an improved high-level input, which offers a more extensive compatibility, some components of the power supply units have been replaced, increasing their stability. This results in a higher maximum output power for each model reflected in the new product name.

Car Specific Series Mono Amplifier
Most multichannel amplifiers offer a satisfying output power for full range loudspeakers but haver a lack of low-impedance stability or simply enough power to drive a demanding subwoofer. Closing this gap, the new installation-friendly class D GZCS A-1.650D mono amplifier offers not only the range of practically required crossover controls and additional features like the bass boost control but can be connected either to the
RCA outputs of the head unit or directly to the speaker wires of the OEM car stereo.
