An acoustic coupler is disposed on the second side of the loudspeaker and extending toward an exterior of the vehicle, the acoustic coupler arranged to transmit the rear wave to the exterior of the vehicle such that the acoustical signal is audible in the interior of the vehicle and at the exterior of the vehicle.
