The only thing I will point out is that the new speakers (no matter what you get) will probably be higher quality than the originals. Of course that means they will be heavier as well. The originals are probably just pop riveted to the door panel. The new ones will stress the composite material of the door panel everytime the door is closed. Eventually the material will fail and your speakers will fall out. To avoid this you need to pick two of the mounting holes that you can install metal screws that go through the panel and into the metal of the door itself (inner portion). It may take a little longer to mark and drill the pilot hole for the screw but it is much quicker than doing the job twice (the second time being after they break out of the composite material)
