Hello,
I'm planning to add an aftermarket hifi system to my base audio F30 330e (2017) - due to various reasons I can only amplify the front speakers -
since I'll switch the HU to HIFI mode (line level output, no EQ) I'm guessing the rear speakers will be disabled/very very quiet -
will this impact the sound volume of the rear parking sensors? Do I have to amplify the rear speakers too?
