Ground Zero GZHA MINI ONE-K 24V 1200 Watt max. Mono class D compact amplifier for 24V use

The Ground Zero GZHA MINI ONE-K 24V is a premium, highly efficient 1-channel Class D compact mono amplifier engineered specifically for 24V electrical systems, making it an ideal choice for heavy-duty commercial vehicles like trucks and buses. By operating natively on 24V, it eliminates the need for bulky voltage reducers, drawing half the current of a traditional 12V system and allowing you to utilize smaller, cleaner power and ground cables.

Despite its space-saving footprints, it delivers a maximum output power of 1200 Watts while preserving premium, audiophile-grade sound clarity that rivals traditional Class AB configurations.
