Speaker locations / sizes in 2008 Stock non-bose?

[dills84]

Hi there, I'm new here. Just bought a 2008 Pathfinder S last week and ditched my old honda civic. Love the truck!

Within 2 days of owning it I swapped out the (complete garbage) stock receiver with a nice Clarion CX501. The sound quality has improved insanely.

My next venture is to replace the stock speakers in the truck. I'm running into conflicting information on the internet.

By eye it seems there are 2 small tweeters in the dash, two 6x9's in the front doors, and 6-3/4"'s in the rear doors.

If I "outfit my car" on crutchfield it only shows the door speakers and no dash tweeters. Anyone know what size the tweeters are? Are they tweeters or speakers? are they a "component" set with the front door speakers?

I'm trying to decide what my best replacement option is... wether it be components using the stock x-over or single door speakers?

Any help is appreciated! Thanks!
