Abstract
An audio entertainment system for a vehicle includes a primary audio entertainment source to play a primary audio program and a secondary audio entertainment source to play a secondary audio program. The system has a plurality of front speakers, a left rear speaker, and a right rear speaker. A headphone set is for private listening by a rear seat passenger to the secondary audio program. The headphone set is selectably connectable to the secondary audio entertainment source. The system has a normal mode and a selectable enhanced rear seat entertainment mode. In the enhanced mode, an output sound power frequency spectrum of the rear speakers is automatically adjustable by frequency band to reduce audible interference between the primary program and the secondary program as audibly detected by the rear seat passenger while minimizing a disturbance to the primary audio program audibly detectable at the front seat row.
