1. A method comprising:
receiving, at an audio system of a vehicle, a direction finding signal from an external speaker, wherein the external speaker is operatively connected to the audio system of the vehicle and located external to the vehicle, and wherein the audio system of the vehicle includes one or more internal speakers;
determining, by the audio system of the vehicle, a location of the external speaker relative to a vehicle reference point, wherein the vehicle reference point corresponds with a center of the vehicle that creates portions of the vehicle relative to the vehicle reference point as a left side of the vehicle and a right side of the vehicle; and
adjusting, by the audio system of the vehicle, a right audio balance and a left audio balance of the external speaker based on the location of the external speaker relative to the vehicle reference point, wherein the adjusting is to dynamically fade the right audio balance to the left audio balance when the external speaker is located at the left side of the vehicle and dynamically fade the left audio balance to the right audio balance when the external speaker is located at the right side of the vehicle.
