AudioControl EPICBIGFOUR

The AudioControl EPICBIGFOUR combines uncompromising performance, audiophile sound quality, and maximum reliability in an exceptionally compact enclosure. With a total output of 1,400 watts RMS and state-of-the-art Class D technology, this 4-channel amplifier delivers powerful, precise sound—even under the most demanding conditions.

Thanks to its high-current design, the EPICBIGFOUR operates stably at 2 ohms and delivers maximum power at all times while maintaining high energy efficiency. The space-saving, thermally optimized housing ensures reliable cooling and allows for easy integration even in vehicles with limited installation space.

To ensure maximum operational reliability, the amplifier features an intelligent protection circuit with automatic reset. It provides reliable protection against overcurrent, overvoltage, undervoltage, DC voltage faults, and overheating. Rugged power and speaker connections with hex screws ensure consistently secure, low-impedance connections.

Using the built-in EPICENTER Link, the amplifier can also be seamlessly integrated with the AudioControl EPICENTER bass restoration processor—for even more deep bass and musicality
