Finally, after much gnashing of teeth, a few expletives, and a new-found appreciation of the pdfs uploaded by Anchorman the Great, I have downloaded the Bose “Terminal Layout and Signal” Codes and Pin Locations for the CX-3.
For LHD models, leaning in the passenger’s door, the Bose amplifier is, of-course, under the passenger’s seat. Taking off the cover, the input wires coming from the Head Unit into the Bose Amp/Processor/Thingie are on the leftmost connector (toward the rear of the vehicle):
So if you wanna’ hook-up your under seat sub (JBL BassPro SL in my case) via the virgin, untainted-by-Bose, low level, line inputs:
1E Front Left Speaker, Negative: White
1F Front Left Speaker, Positive: Black
1G Front Right Speaker, Negative: Red
1H Front Right Speaker, Positive: Green
(Yes, there are two greens on this connector ... you'll just have to note the relative locations of 1H and 1I.)
Here's the pdf:
2017 CX-3 GT, AWD, i-ActiveSense, Ceramic Metallic, Black ... His: Zoom, Zoom!
2016 HR-V EX-L, AWD, Milano Red, Black ... Hers: Putt, Putt.

Reason: Added pdf, added clarity :-)
