I have a 199 dodge durango and all the speakers are blown and i dont know what kind they are. they are infinity but i dont know if they are coxial or midranges and that. and i dont know how to install them cause they have a plastic piece attached to the door that only has 3 screws and a plastics grill built into the plastic door cover to hide the speaker.
search online for a Dodge Durango forum and check their car audio section for information on your system. There's a vehicle specific forum for nearly every car out there, you're bound to find the info you're looking for or at least someone who can walk you through the process.
