Sound systems specifically designed for Mercedes Sprinter built since 2018/03 with a 6-channel amplifier which significantly improve the audio quality of the loudspeakers installed in the vehicle. Any existing living area loudspeakers are driven by the amplifier via a high-pass filter with an optimised frequency response. This way, also these loudspeakers sound more dynamic than before. The version CAS211S is suitable for vehicles with radio pre-wiring. Model CAS212S has been configured for vehicles equipped with 7-inch MBUX (with navigation) and 10-inch MBUX without DSP box pre-installation. Version CAS213S is available for vehicles equipped with MBUX systems featuring DSP box pre-installation.
