The Audison T-Harness "DCC" is the Plug & Play solution for Audi, Mercedes, Porsche, Seat, Skoda, Smart, and Volkswagen cars, for integrating the Audison Prima with the car's factory sound system. The positive battery is taken from the audio unit, without the need to access the engine, thanks to the DCC solution.

The DCC (Direct Cockpit Current) solution can be used in combination with the AP bit amplifier function, which controls the amplifier’s current peaks, protecting the car's power system.
