RADIOACTIVE Amplifier
The RADIOACTIVE series amplifiers offer an amazing high power output up to 6000 Watts in Link-Mode wrapped in a stylish titanium color heatsink containing a wide range of appropriate features for perfect audio adjustment. In a modern car environment, the installation space for an audio system could be very limited, as well. For this reason, the RADIOACTIVE line includes the smallest amplifiers GROUND ZERO ever built. The GZRA MICRO series amplifiers allow uncomplicated and space-saving installation and offer all necessary filters for the sound setup.

RADIOACTIVE DSP Products
Amplifiers with an ISO harness are easy to integrate into an existing audio system. There is no additional wiring needed. In case the car has a brand-specific connector, the car audio market offers a wide range of adapters to convert OEM head units to the ISO standard.

RADIOACTIVE Speaker Systems
Each RADIOACTIVE line speaker has been developed following the market request for dynamical and high-efficient audio reproduction. Particular materials used for the mid woofers and tweeters enhance the performance especially when listening to compressed music files. Apart from that, the NEO offer a significantly reduced installation depth by using high-effective neodymium magnets.
