Just released some sick Coaxials for stock speaker replacement
6.5 comps fit the doors perfectly and the 6x9 coaxials fit the stock location perfect.
I'd run a component set in the front that way you can replace the fatory tweeters while you're at it.
All you'd need to full replace every speaker in the bu would be a pair of 6x9 coaxials and a pair of the 6.5" component set.
Can be had for less than 200$ and the quality will massacre the cheaper ish on crutchfield
