Ground Zero GZRA 4HD 4-channel amplifier

The Ground Zero GZRA 4HD amplifier from the RADIOACTIVE line offers an impressively high output power, packaged in an elegant titanium-colored heat sink that provides a variety of suitable features for perfect audio customization. However, in a modern car environment, the installation space for an audio system can also be quite limited. For this reason, the RADIOACTIVE line also includes the smallest amplifiers that Ground Zero has ever offered. The amplifiers from the GZRA MICRO series allow for uncomplicated and space-saving installation while providing all the necessary filters for nearly any conceivable sound concept. The classic retro design and very compact dimensions of the Ground Zero GZRA 4HD & GZRA 2HD amplifiers hardly hint at the capabilities they possess.
