Ignition Switched +12V (Red Wire)

The ignition switched +12V wire is responsible for supplying power to your radio when your car is turned on. This wire connects directly to your ignition switch, and is usually red in color.

It’s important to note that this wire should only be connected to an ignition switched power source. If it’s connected to a constant power source, your radio will remain on even when your car is turned off, which will drain your battery.

Battery Constant +12V (Yellow Wire)

The battery constant +12V wire is responsible for supplying power to your radio even when your car is turned off. This wire connects directly to your car’s battery, and is usually yellow in color.

It’s important to note that this wire should not be connected to an ignition switched power source. If it’s connected to an ignition switched power source, your radio will turn off every time you turn off your car, and you’ll lose all of your saved radio stations and settings.

Chassis Ground (Black Wire)

The chassis ground wire is responsible for grounding your radio, which is necessary for proper operation. This wire connects directly to your car’s chassis, and is usually black in color.

It’s important to note that this wire should be connected directly to your car’s chassis, and not to any other metal component in your car, such as a seat bolt or door hinge. If it’s not properly grounded, you may experience interference or other issues with your radio.

Power Antenna (Blue/White Wire)

If your car is equipped with a power antenna, the blue/white wire is responsible for controlling the antenna’s motor. This wire connects directly to the antenna’s motor, and is usually blue/white in color.

If your car doesn’t have a power antenna, you can either leave this wire disconnected or connect it to the chassis ground wire.

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

The eight speaker wires are responsible for transmitting sound signals from your radio to your car’s speakers. There are four sets of speaker wires, with each set consisting of a positive (+) wire and a negative (-) wire.

The color of the wires corresponds to which speaker they’re connected to:

  • Gray – Right Front Speaker (+)
  • Gray/Black – Right Front Speaker (-)
  • Green – Left Front Speaker (+)
  • Green/Black – Left Front Speaker (-)
  • Violet – Right Rear Speaker (+)
  • Violet/Black – Right Rear Speaker (-)
  • White – Left Rear Speaker (+)
  • White/Black – Left Rear Speaker (-)

It’s important to note that you should always connect the positive (+) wire to the positive (+) terminal on your speaker, and the negative (-) wire to the negative (-) terminal on your speaker. Connecting them incorrectly can result in poor sound quality or even damage to your speakers.
