Battery (Yellow)

The yellow wire from the head unit should be connected to the positive terminal of your car’s battery. This wire provides power to the head unit even when the car’s ignition is turned off.

Make sure to use a fuse in this wire to avoid damage to the head unit or your car’s electrical system. The fuse should be rated at the same amperage as the head unit’s maximum current draw.

Ignition (Red)

The red wire from the head unit should be connected to the ignition switch of your car. This wire provides power to the head unit only when the car’s ignition is turned on.

Make sure to use a fuse in this wire as well to avoid damage to the head unit or your car’s electrical system. The fuse should be rated at the same amperage as the head unit’s maximum current draw.

Make sure to use a solid and reliable ground connection to avoid noise or interference in the audio signal.

Dimmer (Orange/White)

The orange/white wire from the head unit should be connected to the car’s dimmer switch. This wire controls the brightness of the head unit’s display depending on the ambient light in your car.

If your car does not have a dimmer switch, you can connect this wire to the black wire (ground) to set the display brightness to a fixed level.

Amp Remote (Blue/White)

The blue/white wire from the head unit should be connected to the remote turn-on wire of your car’s amplifier. This wire turns on the amplifier only when the head unit is turned on.

If you do not have an amplifier, you can leave this wire disconnected.

Speaker Wires (Green, Green/Black, Purple, Purple/Black, White, White/Black, Gray, Gray/Black)
