they will be too big, they are going where my factory tweeters were located in my doors. i found a pic of a door online and i marked where the 4" will be going. i have to have 4" cuz the 5.25" will overlap. they are going where those speaker grills are. but i have to surface mount because the locations arent very deep. i have to do a little cutting to get them to fit as well because the holes are about 1/4" too small. would really like a solid black mesh grill.
