2G Bose wiring
 

I'm trying to work something out on the 2G Bose wiring.

Bose in the A8 D3 has 12 speakers?
3 in the dash, 1 in each front door, 2 in each rear door, 2 in the rear shelf and 1 sub?

If that's the case, the below pinouts from the Bose amp doesn't add up to the same amount of speakers.

3/4 - Front right mid-range and treble loudspeaker -R27-
13/14 - Centre mid-range and treble loudspeaker -R158- (–)
7/8 - Front left mid-range and treble loudspeaker -R26- (–)

5/17 - Front left bass loudspeaker -R21-
15/16 - Front right bass loudspeaker -R23- (–)

19/20 - Rear right loudspeaker (–)
21/22 - Rear left loudspeaker (–)

11/12 - Loudspeaker in rear shelf -R150- (–)

T18/1-10 - Sub rear shelf -R157-

It adds up to 9 speakers. So we are missing 3 speakers.
The rear door tweeters and one of the rear parcel shelf speakers?

I'm wondering if the rear door tweeters run off the rear loudspeakers via a crossover and the rear parcel shelf speakers both get the same signal, so count as one speaker?

Anyone able to confirm or suggest an alternative?

Found it in SSP.

Ok that answers that.

On to the next question.
