Understanding the Wiring Diagram

Before we dive into the details of the wiring diagram, it’s important to understand the basics of how radio wiring works.

Most wiring diagrams use color codes to help you identify different types of wires. For example, red wires are typically used for power, black wires are used for ground, and green and purple wires are used for speaker connections. By understanding these color codes, you can easily identify the correct wires and avoid making mistakes during installation.
