It has been know for many years that the highest level of audio performance is achieved at the hands of an expert tuning engineer. It is recently that automotive signal processing options have become overwhelming in their number and variety. In addition, the number of vehicles using model-specific equalization has grown with the introduction of digital signal processing (DSP). It has been observed that much engineering time is consumed before arriving at the perfect tuning. To make the process a bit more “cookbook,” a structured approach is presented.
