2016 SR5 speaker locations

Just got my new truck (SR5 Crewmax) and will be looking to upgrade the audio. I'm looking for help in identifying all the possible speaker locations.

Crutchfield says it doesn't have tweeter locations. However, at the top right/left of dash, by side window defroster vent, looks like a mesh grill for speakers. Is there a speaker there? If not, is it wired for one?

Can anybody tell me where all my speakers are besides in the doors and the center dash?

Also, open to any suggestions on gear that anybody has. Loved the Alpine HU and Infinity speakers I had in my old, old civic (before they got stolen thanks Rochester)

Thanks in advance!

Anybody have any other worthy sites/dealers/ideas?
