OUTLINE
An ASC system is used. A stereo component equalizer assembly generates electrical driving sound based on signals such as the vehicle speed and accelerator pedal depression angle.
Electrical driving sound is output from the No. 1 speaker with box assembly and No. 2 speaker with box assembly to the cabin via a power amplifier that is built into the stereo component equalizer assembly.
The ASC system overlaps the driving sound of the ASC system with the engine sound generated by the movement conditions of the actual vehicle acceleration and deceleration to provide a powerful engine sound to the driver.
