1. A method of improving speaker sound quality in a vehicle, comprising the steps of:

  • determining standard sound ranges based upon the number and positions of passengers in a standard vehicle;

    creating a memory table with data describing the most appropriate speaker angles and sound pressure output levels for each standard sound range;

    detecting a passenger'"'"'s position, number of passengers, and positions of the passengers'"'"' ears;

    selecting the standard sound range that corresponds to the number and positions of passengers in the vehicle;

    finding the speaker angles and sound pressure output levels from the memory table corresponding to the standard sound range from the selecting step;

    adjusting each speaker so that each speaker satisfies the speaker angles and sound pressure output levels from the finding step.
