Can I retrofit some Focal 6x8's components into the doors of my fusion that are 5x7's? I spent a lot of money on a system in my 05 F150 and just sold it to my roommate. I will be taking it all out except the JL audio Stealth Box and was wondering if I could use the door speakers in my new Fusion. I hate to leave them in the truck because they were so expensive. Does anyone know if I can do this?
