Blue and White Wire
The blue and white wire in a car stereo system is typically associated with the remote turn-on function, also known as the "accessory wire". This wire acts as a control signal, indicating when the ignition is switched on and the stereo should be powered.
Key Aspects
- Function: It ensures the stereo receives power only when the ignition is on, preventing battery drain.
- Connection: It connects to the remote turn-on terminal on the stereo's wiring harness.
- Compatibility: The wire color and function may vary slightly depending on the specific car model or stereo manufacturer.
- Troubleshooting: If the stereo doesn't turn on, check for a loose connection or a faulty wire in the remote turn-on circuit.
Remote Turn-on
The remote turn-on function is crucial for a car stereo to operate correctly. Here's how it works:
- Ignition Switch: When the ignition is switched on, a power signal is sent to the remote turn-on wire.
- Stereo Activation: This signal reaches the stereo, activating the power supply and allowing it to function.
- Power Efficiency: The remote turn-on function ensures the stereo only consumes power when the car is running.
