Outside Speaker Size-2009 Montana Mountaineer

[MRBDDB]

My Montana is 2 hours away and I want to purchase a new set of outdoor speakers in our Mountaineer 345DBQ. No clue what size they are but I'm guessing the 5.25 size. Anyone here know for sure?

When it comes to sizes of holes in the outside wall say for speakers not sure I would rely on what someone may think or have on that same year and model. I definetly would not rely on these models being identical. I would check myself, then buy. Just my two cents

5.25 is the most common size for outside speakers. Going through replacement now on mine, I'm finding 5.25 is not common and you need to check depth too.
