speakers for 2002 jeep grand cherokee

Need a little help here guys. According to Crutchfield there are very few speakers that will fit. My plan is for 6 3/4" components in the front doors and 6 3/4' coaxials in the rear doors. The speakers I'm looking at are Infinity Reference or Kappa, Polk dB, and Alpine Type S. Anyone have experience installing these in a Grand Cherokee or have any other suggestions? I appreciate any input you have.

i know your going with comp.s but ive heard the polk 6.5 coaxs an the they were alot more warm sounding than the alpines 1000 watts of lp, now need sum hp an mids

Im not a fan of the Infinity at all. Also they make a 6.75 to 6.5 adapter To put almost what ever you want in. Alot of thoes jeeps have 6x9 in the front, most of the factory infinity systems do, you may want to double check. (the make a 6x9 adapter, or you can make something) Also check into the Boston comps (sc or sr series) Also If you want some amazing sound look at some Focal stuff, Crutchfield has them. In my oppinion they are the best sounding speakers I know of but they can be very expensive.

What is your budget? Dodge Magnum in progress:

Pioneer DEH-80PRS - PPI Amps - Dayton Subwoofer(s) - Exodus Anarchy's - Vifa Tweeters - Kinetik Battery

Metra makes a 6x9 to 6.5 adapter plate for the front speaker locations. 82-6901 is the part number. I know MTX makes a 6x8 component set that would just drop in. I am currently running their 6.5 comps up front and 6.5 coax in the rear doors in my 2001 Grand Cherokee.
