6. Disconnect the Wiring Harness and Antenna: Disconnect the wiring harness and antenna cable from the back of the radio. Take note of how everything is connected for reassembly.

Understanding Car Audio Wiring

Car audio wiring can seem complicated, but understanding the basics will help you connect your new radio correctly. Here are the essential wires you’ll encounter:

• Power (12V Constant): This wire provides continuous power to the radio, allowing it to retain memory settings even when the car is off.
• Accessory (12V Switched): This wire provides power to the radio only when the ignition is turned on.
• Ground: This wire provides a return path for the electrical current.
• Speaker Wires: These wires connect the radio to the car's speakers. There are usually four pairs of speaker wires: front left, front right, rear left, and rear right. Each pair consists of a positive (+) and a negative (-) wire.
• Antenna Wire: This wire connects the radio to the car's antenna.
• Remote Turn-On Wire (Amplifier Turn-On): This wire signals external amplifiers to turn on when the radio is powered on.

Using a wiring harness adapter simplifies the wiring process by providing a plug-and-play connection between your new radio and your car's existing wiring.
