In speaking with Crutchfield they only offer speakers for the front door to which they suggested the Infiniti Reference 3way in 6x9.
The 3 speakers in the dash are 2.5" and they do not have an offering. The 3rd row uses some sort of low profile speaker they also don't offer.
Guess I'll need to look on the Toyota forums a bit.

All my stuff for the truck arrived from Crutchfield yesterday won't get a chance to install all that until Tuesday.
