"well actually the discussion is on 6x9's vs 6.5's of the SAME LINE. not a crappy 6.5 vs a high end 6x9 or vice versa."

then you should have stated that from the beginning. even so, it really depends on the product, even if its from the same manufacturer. and more importantly...the install makes a huge difference. if you find a great sounding 6x9 that fits your pod perfectly, you are golden. thats much better than a great sounding 6.5" that you cant completely seal or dont have the tools (or time) to create a good enclosure for.

to aj: i belive the front speakers are "oversized" 6.5", so most regular 6.5"s will have fitament issues. this can be overcome by creating a simple baffle...just trace the outline of the stock speaker pod, trace the outline of the inner dimentions of your new speaker, cut it all out and slap it into place. depending on the depth of the speaker, you may need to create some shims or use a thick material to construct the baffles. i used 1/2" MDF on my DEI midbass drivers (very small) and still had around 1.5" of room in the back before the windows. if you use the supplied speaker grills, you can push the spakers (with the grills of course) up against the door panels w/ no problem. it may not be cosmetically pleasing, but it will work.

for the rear speakers...is it just a myth that some RS' have 6.5"s in the back? ive never seen one. in case you have that, the same rules apply as what i said above, although im pretty sure your local car audio store will have a 6x9" to 6.5" adapter plate if you dont want to do any work.either way, just make sure the speaker is sealed SOLIDLY to its mating surface and isolate the rear waves from the fronts as best you can.
