I installed an Infinity Kappa 60.5 cs in my 01 Accord V6. I had to cut the back part of the plastic that holds the speakers. Yes a 6 1/2 will fit but depends on the depth. Per Crutchfield catalog, the speakers you have is 2 1/8" deep and the recommended depth is 1 15/16". A little cutting of the plastic and you'll be fine. 
i just bought 60.5cs and did the same thing, cutting out the back of the basket and they fit perfectly. hey bumping, did you find the contour control inside the xover box? if you found it let me know
