what size speakers are in the rear of the Explorer? I was played a fool once when I bought my 6 1/2's for the front doors and realized that they were 6x9's! And I need to know a good set of 6x9's, tight budget, but still want some good quality!
i dont know about crutchfield. i had the same question as you except for my 99 acura tl and after i filled in the information to see "what fits my car" 5 1/4" speaks came up and 6 1/2". mostly 5 1/4" but still! they mixed them up so im still unsure.
its 6x8 in the 4 doors, but i made a bracket to hold 6.5 mid bass in the front doors. adn i have 6x8 in the back polk audio speakers, i got the 6x8 because i wanted the most midbass in the back. sound pretty good man.
get 6.5 speakers fro the front thats all that u need but if u have afew bucks get some polks 6x8 at crutchfield really cheap and worth the money
