* Connect yellow line (Battery) and red line (Ignition) to plus and minus terminal respectively.
* Jack is connected to the audio set via its shapes matched each other.
* We need power supply for operation of audio set (Voltage : 12~15V Current : Over 2A). Before connection between set and power supply, adjust voltage level to 15V typically (It is okay up to 12V.). Power Supply has a variety of shapes and capacity of voltage and current.
