Hey Guys! I own a 2004 BMW 745i. Recently my left and right central bass went out, got it checked by the dealer and they they said it was just the speakers. Im buying the speakers myself second hand and will have a BMW certified mechanic install them but my question is this, My 7series has the logic7 sound system. Does it matter if the speakers come out of a 7 that did not have the logic7? Or do I just need to make sure its for a e65? Please help me out!
