  • External amplifier interface
    Patent number: 9875078
    Abstract: An interface configured to allow desired cooperation between an OEM or aftermarket head unit and an external power amplifier. The inventive interface receives an audio input signal from the head unit. It also monitors the vehicle's CAN bus. The interface detects CAN bus commands that cause the head unit to play an audio notification signal such as a “chime.” Upon detecting such a CAN bus command, the inventive interface selectively adjusts the output level so that the user hears the audio notification signal at an appropriate volume.
