A vehicle audio system comprising a memory connected to a controller, wherein the controller is configured to perform the method comprising:

• i. receiving data for being output through a portable audio device located outside a vehicle and one or more internal speakers mounted inside the vehicle;
• j. determining a distance and/or a position of the portable audio device with respect to the vehicle;
• k. processing the data based on the determined distance and/or position of the portable audio device;
• and
• l. controlling the one or more internal speakers to output the processed data;
• wherein the data is processed such that a frequency response of an output of the one or more internal speakers is adjusted based on a frequency response of the portable audio device.
