Features

4/2 Hole Compatibility: Most 4" factory speakers use four mounting screws, however, in some vehicles, only two are used. The KSC40's mounting tabs can be removed, allowing installation in 4-hole or 2-hole applications. Care should be taken handling the speaker after any tabs are removed because the broken edges may be sharp. Please enter your vehicle information to confirm fit.

Greetings Daniel, and thank you for your question. These will fit depth wise, and height wise. To get them in you may need to trill some of the Kicker mounting ears, and re drill new screw holes in your door.

Yes it will if it has the same radius of inches on the speaker hole. For example if you purchased the kickers for the front doors to fit then you should have no problem of fitting the speakers in. It all depends on the size of speaker size that you recently purchased at Cruthfield. You see I purchased mine on my 1996 Toyota Corolla front doors that is only 4inches in a half.
