How to Install an Aux Input in a Car Radio191

An auxiliary (aux) input allows you to connect an external audio source, such as an MP3 player or smartphone, to your car radio. This can be a great way to upgrade your car's audio system without having to replace the entire radio. Here are the steps on how to install an aux input in a car radio:

Materials you'll need- Aux input adapter
- Wire strippers
- Crimp connectors
- Electrical tape
- Soldering iron (optional)

Step 1: Remove the car radio- Consult your car's manual for specific instructions on how to remove the radio. In general, you will need to remove the trim panel around the radio using a plastic pry tool. Once the trim panel is removed, you will have access to the screws that hold the radio in place. Remove the screws and pull the radio out of the dash.

Step 2: Identify the wiring harness- The wiring harness is a bundle of wires that connects the radio to the car's electrical system. Locate the harness and identify the wires that are responsible for audio input. These wires are typically color-coded, with the left audio input wire being white, the right audio input wire being red, and the ground wire being black.

Step 3: Cut the wires- Cut the audio input wires about 6 inches from the harness. Be careful not to cut any other wires.

Step 4: Strip the wires- Strip about 1/4 inch of insulation from the ends of the audio input wires.

Step 5: Crimp the connectors- Crimp female spade connectors onto the ends of the audio input wires.

Step 6: Connect the aux input adapter- Connect the aux input adapter to the female spade connectors on the audio input wires. The adapter should have a 3.5mm jack on one end and two male spade connectors on the other end.

Step 7: Solder the connections (optional)- For a more secure connection, you can solder the connections between the aux input adapter and the audio input wires.

Step 8: Wrap the connections with electrical tape- Wrap the connections with electrical tape to insulate and protect them.

Step 9: Reinstall the radio- Reinstall the radio into the dash and secure it with the screws.

Step 10: Test the aux input- Connect an external audio source to the aux input jack on the front of the radio. Turn on the radio and select the aux input source. You should now be able to hear audio from the external audio source through your car's speakers.
