Speaker Dunce.. easy question I'm sure..
 

So Crutchfield says that 6.5's go in the rear and 6x8's go in the front.

Crutchfield doesn't show any 6.5's that would go in my car.

I'm really wanting some Infinity Kappa's and they have an awesome buy one get one 50% sale right now.

I've been told that 5"x7" will work in both the front and the back. IS THIS TRUE??? I really don't want to order the wrong ones then have them be too small or too big.

I'd like to order
Infinity Kappa 572.5cf _5"x7" 2-way Speakers by the end of the month if someone can confirm.

To sum up my rambles.. what WILL work in my 2003 Protege 5 without any modifications??

Please advise.

ps- I do plan to use Dynamat Speaker kits on all doors.

5x7 up frony, yes. and rear, 6.5's fit, but you need to trim back some plastic rings. 5.25's fit w/o modification. However, if you go with those speakers, you WILL want an amp, and, well IMHO you can do better (Look at what speakers I have, 5x7kappa's) they sound alright, but if your'e buying 2 sets and an amp, for that kinda money you can very easily get a 2channel amp and a very nice set of components from upfront that'll sound much nicer (and rear speakers aren't really good to be loud anyway)
