Thanks to the built-in USS technology (Universal Speakers Simulator), DIECI POWER amplifiers can be correctly connected to head units with a “speaker load detection” function that monitors the presence of a low-impedance load to enable the audio outputs.
Dieci Power amplifiers are ultra-compact to ensure effortless installations in the increasingly narrow spaces of modern vehicles or the factory amp area.
