Use RADIO to turn on accessories with a RELAY! EXPLANATION & WIRING

When building a complex car audio system you may have other accessories that you want to turn on, things like cooling fans, LED lights, and other items. We want these items to be powered whenever our audio system is on, but the radio only provides a small amount of current for its remote turn on circuit. How can we provide much more current? We can use a relay! Here’s how to wire, and use a relay explained! 🔊 Not sure how to remove your stock radio, stock speakers and other components in the factory system?
