Audio systems and assemblies provide for a loudspeaker acoustically coupled to an interior of a vehicle and externally ducted to an exterior of the vehicle. The loudspeaker may therefore be subject to a pressure differential existing between the interior and the exterior that may cause undesirable operation, such as an altered acoustic response and/or damage to the loudspeaker. The systems and assemblies provide for various mitigating actions that may include altering an audio signal to change the acoustic response, turning off the loudspeaker, and/or isolating the loudspeaker from the pressure differential.
