Como conectar a fonte de alimentación no coche?

• ACC (vermello), supplies +12V power to car audio and other accessories, only when the car’s ignition is switched on.
• Constant (amarelo), also called BAT or Battery, provides permanent +12V power from the battery. This allows the radio to retain settings (for example stored radio stations) when the ignition is switched off.
• Chan, abbrev. as GND (negro), 0V, is usually connected to the vehicle’s metal chassis and body.
