How to Install an Auxiliary Jack in a Car

10

Car stereo auxiliary, or AUX, outputs give motorists the ability to connect a variety of audio devices to their car’s sound system using a standard 1/8-inch to 1/8-inch stereo audio cable. Auxiliary ports have almost become a standard feature for newer car stereos, but many older stereos don’t include one. If your car stereo doesn’t include an auxiliary port, you can skip the car audio shop and add your own.

Items you will need: Auxiliary input adapter, RCA to AUX cable (female), Car manual

Step 1

Assess your car stereo to determine what removal method will be needed. If the radio is bordered by your car’s interior trim, you will need to remove the screws from the trim and pry it away from the stereo. If there is no trim, you’ll need DIN tools to remove the radio. Reference your car’s manual for details.
