That is what I thought also.
But when I was installing my Nav radio I swear I found the tweeter wires way up in the dash bundled up.
The wiring colors match what is in the service manual.
I did not have any time to test, trace , confirm as I was reassembling on a schedule.
But I just got a set of Infinity 10.7t kappa 1" tweeters in the mail and should be installing them this weekend.
I will let you know if those are the tweeter wires up there already.
