    Is there a way to add an aux input to the stock 03 Lancer stereo system? If so, could you please provide me the information on where I could get the wire and connectors and any other things that might be required. Thanks in advance.

    Raj, you will need an automotive auxiliary input adapter. This adapter will allow you to input any mp3 player or portable music player into your factory radio. This is the easiest and most cost effective way to add an audio input into your factory stereo. Here is the adapter you will need:
