Notice that in this list of GM RPOs, in the "U's" in the alphabet are lots of Bose categories. I wasn't able to find one specifically for the Intrigue -- yet.

In some of the promotional material if available you may be able to tell by the number of speakers or the placement. You'll have to search the internet.
A friendly dealer can enter your VIN and get a printout of the options on that vehicle, which would use the RPO letter codes as the key on each option or package. If you've had it service at a dealer, that might be a good place to start since they seen you as a customer.
You can act like you're buying a radio but don't know if you have Bose speakers or not and send an inquiry by
the ebay site to this seller asking them how to tell...

I'm guessing that the Bose system has an amplifier on the speakers. Often things like that are tacked on the underside of the rear window metal deck inside the trunk.

Bose Audio option on GL and standard with GLS precision sport package?
Note picture of Bose system on page 18 (at the top of the pdf player) and there it mentions 8 speakers.
The other systems don't have 8. On page 14 the car interior is a Precision Sport model so I assume that
radio is the one with the Bose system speakers.
Note in Win 10, if you press ctrl and F, you get a search box in upper right, where you can type
"BOSE" and then find 4 occurances. The up carat and down carat will take you to each of them in the brochure.
