The ones in the front seats are directed towards the back seats . That’s why u don’t get any in the backHi Chris
I've just purchased a 21 plate Juke Tekna +
It has the Bose speakers in the headrests and I was trying to work out how to adjust the audio fader/balance from front to rear (which there is no setting for) and thats how I discovered it doesn't actually have any speakers in the back door!
I must admit I assumed the car had a full complement of speakers and the Bose headrest ones where extra additions.
