Abstract: A system and method is disclosed for improving the audible output of a vehicle radio based upon the particular type of vehicle in which the radio is installed. A vehicle radio includes a data table, which is accessible by a radio controller. The data table stores a plurality of unique sets of alignment parameters. Each set of alignment parameters corresponds to a vehicle model in which the radio may be installed. The alignment settings are used to adjust various signal-processing techniques—such as “blend”, “roll-off”, “noise blank”, etc.—as well as other parameters. The radio controller receives information indicative of the type of vehicle in which the radio is installed. The radio controller accesses the data table and applies the alignment settings that correspond to the type of vehicle. Listener-specific preferences can also be stored in the data table.

Each feedback circuit provides a feed back path from the drain of one of the output transistors to the gate thereof. The resistors are polysilicon type resistors and have a negative thermal coefficient. The amplifier has a very stable output signal amplitude which is essentially independent of integrated circuit manufacturing processing variations and operating temperature variations within useful ranges.
