GAS Audio MAD A2-85.2

The GAS Audio MAD A2-85.2 was developed for demanding car audio applications and combines the sonic advantages of powerful Class AB technology with sophisticated features for versatile sound systems. Thanks to clean signal processing, high output power, and extensive filter functions, the amplifier is suitable for both high-quality front systems and for driving a subwoofer in bridge mode.

The robust heat sink design with optimized airflow ensures reliable heat dissipation even under heavy loads. Symmetrical differential inputs effectively reduce interference and enable clean signal transmission. In addition, high-level inputs with an automatic turn-on (ATO) function, an integrated CLIP indicator, and comprehensive protection circuits simplify installation and daily operation.
