Everyone on this board has differant and mostly good opinions. Listen to major brand names with close to the same power you are running and pick out what sounds best and is in your price range. ( My favorite, JL XR 570 csi )

Kind of a wide open question, what kind of price range are you trying to stay within?? And as tcss has stated, everyone is going to have different opinions, but the most logical solution is to get a few ideas within your price range, and go to your local dealers and demo them yourself and pick out what sounds best to you.

Try looking into MB Quart, Focal, Morel, Eclipse, Infinity, Boston Acoustics, Just to give a few, I'm sure you will get others.

Also look into Adire, and Diamond Audio. Both make an excelent component set-up but, go with silk tweeters.

If you have 6x8's now, why wouldn't 6.5's fit?

If you have 6x8's in the doors now, then you should have pleanty of room for a set of 6.5" Components. You will just need too either make and adaptor ring or buy one like this:
