The board efficiently eliminates problems caused by wiring resistance and removes noise generated by other electrical devices used in automobile environment. In a car or automotive the audio system is grounded to the car body. For this reason, electrical noise generated by the car electrical system can enter the power amplifier input through the chassis and become audible.
