Claim Text:
1. An amplifier docking audio system for a vehicle, comprising: a docking space in an audio body; a docking connector disposed on a printed circuit board of the audio body; and an external amplifier coupled to the docking connector of the audio body in the docking space to be connected to the printed circuit board of the audio body, wherein when the external amplifier docks with the docking connector to be connected to the printed circuit board of the audio body in the docking space, processing and outputting of audio signals are performed, and wherein the audio body further comprises: an embedded amplifier that amplifies and outputs the audio signals; a docking sensor configured to sense whether or not the external amplifier is docked; a switching device (S/D) configured to switch a circuit connected to audio signal input terminals of each amplifier such that the audio signals are delivered and outputted to or from only the embedded amplifier or delivered and outputted to or from both the embedded amplifier and the external amplifier; and a switching controller configure to output a control signal for controlling switching driving of the S/D according to a docking result of the external amplifier sensed by the docking sensor.
