Power Wire: The power wire (usually red) should be connected to a 12-volt constant power source, such as the battery or the fuse box.
Ground Wire: The ground wire (usually black) should be connected to a metal surface in the car that is grounded, such as the chassis or the body.
Speaker Wires: The speaker wires (usually four - two pairs) should be connected to the corresponding speaker terminals on the back of the stereo. The front speaker wires are typically white and white with a black stripe, while the rear speaker wires are typically gray and gray with a black stripe.
Antenna Wire: The antenna wire (usually blue) should be connected to the antenna input on the back of the stereo.
Illumination Wire: The illumination wire (usually orange) should be connected to the headlight switch or another source of lighting in the car. This will cause the stereo to dim when the headlights are turned on.
Amplifier/Subwoofer Output: If your stereo has an amplifier or subwoofer output, these wires should be connected to the corresponding inputs on your amplifier or subwoofer.
Note: It is important to follow the provided wiring diagram for your specific model and year of car. Failure to do so may result in damage to the stereo or your car's electrical system. It is also recommended to consult with a qualified car audio technician if you are unfamiliar with car audio installation.
