Speakers

I have a 97 mits eclipse without the infinity speaker package, and i was wondering if anyone knows the max speaker depth you can get away with in the front and back. Was hoping to get Infinity kappa's but according to crutchfield they wont fit, nor will most somewhat higher end speakers. Any info would be appreciated before i go and rip off the door panel just to measure.

i'm not sure..go to http://www.crutchfield.com to see if they'll fit
