วิธีต่อไฟเข้ารถ?

• แม็ก (สีแดง), supplies +12V power to car audio and other accessories, only when the car’s ignition is switched on.
• Constant (สีเหลือง), 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.
• พื้น, abbrev. as GND (สีดำ), 0V, is usually connected to the vehicle’s metal chassis and body.
