I was wondering what is the exact sizes to replace the factory blown out speakers in my car? I tried different websites and they give me different answer some say a 6x9 fit in the rear then the other says 6 1/2 fits front and rear.

6 1/2 is the size of the speakers for front and back.

Crutchfield.com <--- all the info you need, and they have almost unbeatable prices on everything plus they give you a lot of extras that most local speaker shops will nickel and dime you for.

I have No idea.....
It's nice.....
