Installing Tips & Tricks MS-8
Before installation examine the OEM system
o Park distance control
• Determine if the sound of park distance control is played through front/rear or front and
rear. (BMW often processes PDC signal front by front speakers and PDC rear by rear
speakers)
o Carkit
• Determine if the sound of carkit is played over front and/or rear speakers
o OEM audio system
• Determine what kind of system you’re dealing with (active or passive, in- or excluding
subwoofers, can you adjust the level of the subwoofers)
• Determine Xover frequencies of the original system (Tip: measure signal with pink noise and
analyzing software to analyze frequency response and Xover points)
• If the OEM system has noise cancellation disconnect the echo cancellation microphone or
disable it by a switch
