Abstract
An audio system for use in a passenger compartment of a vehicle. The system includes a front-driver side speaker unit and a front-passenger side speaker unit to cooperatively emit audio sound to the passenger compartment. The driver-side speaker unit includes a primary speaker and a secondary speaker to produce sound in cooperation with a primary speaker and a secondary speaker of the passenger-side speaker unit. An audio control system is configured to compensate for unbalancing of stereo images at front-driver/passenger positions by controlling output from the secondary speakers based on output from the primary speakers.
