Abstract: A multi-channel audio system can be installed into any of a plurality of acoustically unique vehicle environments. A digital signal processing system for processing source audio signals generates a plurality of audio output signals to be coupled to audio transducers, wherein the digital signal processing system includes a multi-channel equalization filter. An equalization coefficient memory stores a plurality of equalization characteristic sets, each equalization characteristic set corresponding to a respective one of the vehicle environments. A controller couples a selected one of the equalization characteristic sets to the multi-channel equalization filter in response to a vehicle environment identification signal.
