PURPOSE: An output device of a car audio is provided to supply the original sound with feeling the surround sound by feeling the distance between the driver and each of the speakers equal to each other. CONSTITUTION: An output device of a car audio includes an audio controller(10), a DSP signal processing block(20) and an amplifier(30). The DSP signal processing block(20) controls the delay time from each of the speakers so as to make the reaching times from each of the speakers to the driver's seat equal to each other by DSP signal processing the audio signal outputted from the audio controller(10). And, the amplifier(30) controls the audio controller(10) so as to allow the user to hear the sound from each of the speakers with the equal amount at the driver's seat by differently amplifying the audio signal corresponding to each speaker outputted from the DSP signal processing block(20) with different amplification values.
