FIELD OF THE INVENTION 
       [0001]    An audio system for use in an automotive vehicle is provided. More particularly, the audio system is configured to transmit a plurality of audio signals based upon the destination and vehicle settings so as to provide a predetermined audio output. 
       BACKGROUND OF THE INVENTION 
       [0002]    Currently automotive vehicles are provided with an audio system having a signal processor configured to provide a predetermined audio signal. The audio signal is determined by the vehicle setting and the destination of the vehicle. In particular, the audio signal may be configured to account for vehicle settings (to include the various vehicle interior components) and the destination of the vehicle so as to provide a desired audio output. 
         [0003]    It should be appreciated that materials may affect the audio output. Accordingly, the audio signal is tuned to account for the different interior components so as to generate a predetermined and desired audio output. Thus, manufacturers provide a plurality of different audio systems each of which is configured for a specific vehicle type and the destination of the vehicle type which may result in numerous different audio systems. 
         [0004]    Accordingly, it remains desirable to have an audio system configured to be used in multiple vehicles arriving at multiple destinations so as to reduce the number of signal processors available to choose from thereby streamlining the manufacturing process and reducing cost.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0017]    An audio system for use in an automotive vehicle is provided. The audio system is configured to generate one of a plurality of audio outputs so as to allow vehicles with different interior components and destined for different geographic regions to have a desired audio output. The system includes a signal processor such as an amplifier. A database including a plurality of audio signals may be stored in an engine control unit of the vehicle. Each of the audio signals is associated with a geographic region. The system further includes an input configured to select one of the geographic regions wherein the signal processor processes the audio signal associated with the selected geographic region so as to generate a corresponding audio output. Accordingly, the system allows manufacturers to install one amplifier for which the signals generated by the amplifier are provided by a database and which is appropriate to the interior components of the vehicle and the destination of the vehicle. 
         [0018]    With reference now to  FIG. 1 , an illustrative view of the audio system is provided. The audio system is mounted within an automotive vehicle. The audio system includes a digital signal processor. The digital signal processor may be an amplifier. The digital signal processor processes an electrical signal and transmits the signals to the speakers shown mounted at various locations of the vehicle. Each signal to a respective speaker is configured to provide a predetermined audio output wherein the collective audio output of a respective speaker provides the system with a desired audio output. The database is shown stored in the vehicle&#39;s body electronic control unit. The body electronic control is a processor configured to process and transmit signals from various electronic components. The database includes a plurality of audio signals. Each of the audio signals is associated with a geographic region. The audio system may further include an input. The input is configured to select one of the geographic regions. Upon actuation of the input the signal processor processes the audio signal associated with the selected geographic region so as to generate a corresponding audio output. It should be appreciated that the audio signal is an electrical signal sent to a respective speaker and taken together produces the audio output. Thus, the electrical signal to a speaker such as a tweeter may not necessarily be the same as an electrical signal transmitted to a subwoofer or a woofer. 
         [0019]    With reference now to  FIG. 2 , a schematic diagram showing the operation of the audio system is provided. As shown, the signal processor receives an audio signal from the body ECU. The audio signal is selected by the input based upon the geographic region of the vehicle and as described further below may also include the interior components of the vehicle so as to provide the vehicle with a predetermined audio output. The selected signal is then processed by the signal processor and the signal processor transmits a signal to the radio or the speakers to provide the corresponding audio output. 
         [0020]      FIG. 3  is a chart showing the various materials for certain interior components of the vehicle. It should be appreciated that the vehicles may have different components for which different materials are used to make the components and the different materials provide different acoustic responses and thus having a common tuning for different interior components may result in different sound qualities. Accordingly, the system is configured to provide a plurality of audio signals based upon the different components within a vehicle and each of which provides the same audio output for a specific geographic region. Thus,  FIG. 3  for example shows that the North American geographic region has a predetermined audio output which is different than the predetermined audio output for China, Europe, and Japan. It should also be appreciated that the North American audio output may be achieved by different signals which take into consideration the interior components. For example, the audio signal for a seat formed of leather with a soft instrument panel and soft door trim has a first signal designated as tuning  1 A whereas a vehicle with cloth seats, a soft instrument panel, and soft door covers has an associated audio signal designated as tuning  2 A. It should be appreciated that a vehicle designated for North America will have the same predetermined audio output when the associated tuning is used for the marked interior components. Thus, signals  1 A and  2 A produce the same audio output despite the fact that the signals are different as the signals account for the interior components. Accordingly, the audio system allows the manufacturer to provide a single or common digital signal processor for each vehicle regardless of the differences in interior components and regardless of the destination of the vehicle. As illustratively shown in  FIGS. 4-7 , the system provides a database which may be written into the electric control unit of the vehicle and an input that selects the appropriate tuning and destination. Accordingly, the manufacturing cost and process is streamlined as the manufacturer no longer has to order different digital signal processors for each vehicle and does not have to remember which digital signal processor is appropriate for a geographic region or vehicle setting. 
         [0021]    With reference now to  FIG. 8 , a method for manufacturing a vehicle is provided. The method manufactures an automotive vehicle so as to provide the automotive vehicle with an audio output associated with the geographic region the automotive vehicle is destined for. The method proceeds with step  1  wherein a signal processor is provided. The signal processor may be a digital signal processor such as an amplifier. The method proceeds to the step of providing a database. The database is configured to store a plurality of audio signals. Each of the plurality of audio signals is associated with a geographic region. The database may be downloaded onto the engine control unit of the automotive vehicle. The method proceeds with the step of providing an input. The input is configured to select one of the geographic regions. The method proceeds to the step of selecting the geographic region the automotive vehicle is destined to be sold in wherein the signal processor processes the audio signal associated with the selected geographic region so as to generate a corresponding audio output wherein the selection of the geographic region is completed before the automotive vehicle leaves the manufacturing facility.
