The SE model comes with 8 speakers standard. Aside from the pair of tweeters in the front, a pair of speakers in the front(doors) and a pair a pair of speakers in the cargo area, where is the last pair located?

The speakers in my Xterra SE SC are what you mentioned as well as a pair in the middle doors. They are there - you just have to look for them.

The speakers in the cargo area are dual-cone...Woofer and tweeter. Hence "8 speakers in 6 locations"

BTW I have had the rear interior panels and speakers out myself...I know it is true

Thanks Pacopico, that explains it! BB02SESC...I think you'd better check those "middle doors" again.
