One of the most popular upgrades for car audio systems is the addition of an auxiliary input, which allows you to connect external devices such as smartphones, MP3 players, and tablets to your car stereo. In this guide, we will walk you through the process of installing an auxiliary input in your car stereo, including the tools and equipment you will need, as well as step-by-step instructions for the installation process.
Tools and Equipment Needed
3.5mm auxiliary input cable
Optional: soldering iron and solder (if wiring needs to be spliced)
Step 1: Locate the Head Unit
The first step in installing an auxiliary input in your car stereo is to locate the head unit, which is the main control unit for your audio system. The head unit is usually located in the dashboard of your car and can be identified by its display screen and control buttons.
Step 2: Remove the Head Unit
Once you have located the head unit, you will need to remove it from the dashboard. This process can vary depending on the make and model of your car, so it’s best to consult your car’s owner manual for specific instructions. In most cases, you will need to use a screwdriver to remove the screws that hold the head unit in place, and then carefully disconnect any wiring that is connected to it.
Step 3: Connect the Auxiliary Input Cable
With the head unit removed, you will now be able to access the back of it. Locate the input for an auxiliary cable, it is often labeled as “AUX” or “LINE IN”. It should be a 3.5mm audio jack. Connect the auxiliary input cable to the head unit by plugging one end of the cable into the “AUX” or “LINE IN” port, and the other end into the external device you want to play the audio from.
Step 4: Reinstall the Head Unit
With the auxiliary input cable connected, you can now reinstall the head unit back into the dashboard. Make sure to reconnect any wiring that was disconnected during the removal process, and then secure the head unit back in place with the screws you removed earlier.
Step 5: Test the Connection
Before putting your car back together, turn on your car and external audio device, set the audio device to play, and turn on the car’s stereo. You should be able to hear audio playing through your car’s speakers. If the connection is not working, check to make sure that the auxiliary input cable is securely connected, and that the audio device is set to play.
