@Ryan Just to clear it up the typical HiFi speakers would have a tweeter in the pillar and one speaker on the door = 2 speakers each door at the front, however for the i4 they have changed the design and removed the tweeter in the pillars and added 2 separate speakers on the actual door, one near the handle and one where you store water bottles, which add up to 2 speakers per door just like the HiFi.
