Need a little help.

My passenger side rear speaker sounds bad. I own a 2004 Limited Coupe.

Before I go and take out the rear speakers I would like to know what size they are and are they 2-way, 3 way or 4 way? Are they 6 1/2 inch?

I would like to buy the replacement speakers and while everything is torn apart just put the new ones in.

Any help would be great. Thank you.
