How to install Aux input in car stereo?

Installing an auxiliary input into a car stereo can be a great way to add more functionality to your music listening experience. By adding an auxiliary input, you can connect any device that has a 3.5mm audio jack to your car stereo and play its music through the car’s speakers.

This process is relatively simple and can be completed in just a few minutes using common tools and supplies.

How to install Aux input in Car Stereo

The following steps will guide you through the process of installing an aux input in your car stereo.

1. What you’ll need:

  • A car stereo with an aux input (or a car stereo that can be modified to have an aux input)
  • A 3.5mm audio cable
  • A blank cassette tape

Step 1: Remove the faceplate from your car stereo.

On most car stereos, the aux input wires will be clearly labeled. If your stereo does not have an aux input, you may be able to find a wiring diagram online that will show you where to find the aux input wires.

Step 4: Route the audio cable to the location of your aux input device.

Thread the audio cable through any openings or crevices in the dash until it reaches the location of your aux input device.

Step 5: Connect the 3.5mm audio cable to your aux input device.

This can be any device that has a 3.5mm audio jack, such as an iPod, iPhone, MP3 player, or smartphone.

Step 6: Insert a blank cassette tape into the car stereo.

This will trick the stereo into thinking there is a cassette in the deck, which will allow you to play music through the aux input.

Step 7: Connect your aux input device to the car stereo and press play.

The music from your device should now be playing through the car stereo. Enjoy!
