PURPOSE: A vehicle amplification system apparatus provided with a digital processing function and a communication function of a signal control information is provided to enlarge the selection of the accessory such as an amplifier and a speaker or the like. CONSTITUTION: A vehicle amplification system apparatus provided with a digital processing function and a communication function of a signal control information includes an external communication block(200), a microprocessor(300), a memory(350), a key input pad(330), an analog-to-digital(AD) convertor(310), a digital-to-analog(DA) convertor(320), a display device(400) and an amplifier(500). The microprocessor(300) performs a communication with the external communication block(200) as well as performs the signal process. The memory(350) stores the information of the adjustment state. The key input pad(330) controls various functions. The AD convertor(310) converts the external analog signal into a digital signal. The DA convertor(320) converts the digital audio signal into analog signal. The display device(400) displays the various status and the amplifier(500) amplifies the analog signal from the DA convertor(310).
