If you accidentally connect the remote wire of your car audio system to the wrong type of wire, you run the risk of encountering issues with your car amplifier. The remote wire is responsible for remotely controlling the amplifier, instructing it when to turn on and off. To resolve this issue and ensure proper functionality, follow these steps:

  • Remove the car stereo from the din slot located in the dashboard to access the wiring harness at the back.
  • Identify the remote wire on the reverse side of the wiring harness and determine which wire it is connected to. Use a multimeter to check if there is still voltage present when you turn the key in the ignition.
  • If you find that the voltage remains even when the vehicle is turned off, you have located the source of the problem.
  • Now, you need to identify the correct wire. Most wiring harness plugs have wires that are either blue or blue and white striped, and the corresponding wire for the remote is typically also blue or blue and white.
