I replaced mine with Diamonds in front and then got cheep and used Pioneer in back. They sound sooo much better. Your can use the fractory speakers as a mount for the new ones. Cut arround the speaker cone's ourtside edge and use metal shears or a hot sodering iron to cut though the struts holding the magnet close to the out side . cut the woven wire conectors close to the magnets as you can use them to connect the new speakers and preserve the original plug conector. You can secure the new speaker to the flange on the old speaker frame either directly with screws or if you want to trim the length of the clips that come with the new speakers they will work. When you are done you can secure the old speaker back to the door with 3/4 #12 or 14 ( i've forgoten which)screws. When I screwed the new speaker directly to the flange I put some "Liquid nails" on the bottom side of the flange were the screws came through to prevent the screws from backing out. If you get speakers with separate cross overs you will have to cut some wires. I had to do this in the front with the separate tweeter. To "mount" the cross over so to keep it from rattling I used the areosal insulating foam in the bottom of the door. If i did it again I would use foam rubber so it would be easier to remove if I ever had to.
