How To Install Aux Cord In Car?

Installing an auxiliary port is a straightforward and affordable way to upgrade an older vehicle and make it compatible with your device of choice. Connect one end of an AUX cable to the bottom AUX input on your speaker while inserting its other end into an audio device’s AUX output port for optimal connectivity.

How to Install an Auxiliary Jack in a Car?

Car stereo auxiliary, or AUX, outputs enable motorists to connect a variety of audio devices using standard 1/8-inch to 1/8-inch stereo audio cables to their car’s sound system via an AUX output. Auxiliary ports have become almost standard features of newer stereos; if your older Stereo doesn’t include one, you can easily add your own.

Consider your car stereo before determining how best to remove it. If the radio is bordered by interior trim, remove its screws before prying away to free the Stereo from it. Otherwise, DIN tools will likely be required; refer to your owner’s manual for more details.

Make a note of your Stereo’s model number. The stereo audio output varies considerably between models, so having its model number will help you locate an adapter suitable for its audio output. Stereos with red and white RCA outputs require only an RCA to AUX cable; otherwise, you should apply a parking brake and pop hood before disconnecting the negative battery terminal (black). To prevent shorting your equipment during setup:

Remove all trim and screws securing your radio to the dashboard, or insert two DIN tools into the four holes on its front face to pull it out from behind. Either way, slide out from underneath after all trim is removed or use DIN tools.

Connect the DIN connection of an auxiliary input adapter into an available port on the back of your Stereo, and connect its red and white RCA cables with those found on an RCA to AUX adapter if it already features them on its side. If your Stereo already features these ports, match up these adapter’s red/white plug-ins with those already on its sides for seamless use.

Feed the auxiliary end of an RCA to AUX adapter into the car’s seating area through either its back glove compartment or the bottom. Remove a side panel from your center console through either route – either through the back of the glove compartment or the bottom of the center console.
