I have searched the forums and see that a lot of people have used the Infinity Kappa series to replace the front and rear door speakers. I checked the speakers that fit sticky and found one person say that he was able to mount the Infinity Kappa 62.9IS in the front doors. They are the shallow mount so I figure they will fit. My real question is how (where) to mount the external crossover. Anyone who has mounted these speakers got any tips or suggestions?
