Amplifier for vehicle and vehicle including the same
The present disclosure provides an amplifier for vehicle, vehicle including the amplifier, and method for controlling the amplifier for vehicle, which uses a 48 volt (V) battery voltage and adjusts speaker output according to variable audio signals, thereby minimizing the size of the amplifier, reducing conversion loss of a Direct Current (DC)-to-DC converter, and increasing output efficiency. In accordance with one aspect of the present disclosure, An amplifier for vehicle includes a first input port for receiving a first voltage; a second input port for receiving a second voltage lower than the first voltage; at least one power Integrated Chip (power IC) connected to a speaker for using a voltage received from the first input port; and a controller for controlling the power IC using a voltage received from the second input port.
