Audio jacks are found on many types of audio equipment and musical instruments that accept items plugged into them. In a car, an audio jack, (also called a "media jack" or "auxiliary (AUX) jack,") is a small phone socket that connects any portable music player to the vehicle's amplifier, which is the place where you can plug in in, and speakers. Also, you can plug in to a CD.
