Car Stereos: Speaker Size, dodge durango sxt, dodge durango

Question
I have a 2002 Dodge Durango SXT and would like to replace the door speakers but have no clue as to the size speaker needed. Do I have to have a certain size and if so what size would that be?

Answer
Chrissie,  The easiest way that I have found to determine what size speakers a specific vehicle has in it, is to go to crutchfield.com .  They have a database with every car in it.  Just pick your year, make, and model, and they will recommend what speakers to replace your factory speakers.  Hope this helps, Scott
