Auxiliary cords allow you share you music in more locations.
Using your car radio as a speaker for your guitar is possible as long as your guitar has electric capabilities. Electric guitars will certainly be compatible with usable car radios, but you may also be able to hook up your acoustic guitar if it can be plugged into an amplifier. VW even created a marketing campaign in 2006 where they offered a free electric guitar with the purchase of a vehicle. In their advertisements, VW boasted about how crisp the sound of the guitar would be when hooked to a car's speakers. Begin playing your music through your car radio using these steps.
Instructions
1. Check to see if your car has an auxiliary plug in. The plug would be a small, round hole or port labeled "AUX." If not, make sure your car has a tape deck. If you do have an auxiliary plug or a tape deck, your guitar cannot be plugged into your car's sound system.
2. Purchase a basic auxiliary cord if your car has an auxiliary plug. If you have a tape deck instead, purchase the auxiliary cord with the tape deck adapter.
3. Attach the auxiliary cord to both the car and the guitar. Turn down the volume, bass and treble features of your radio significantly before playing a single note on your guitar. This will prevent damage to your car's speakers.
