I am looking at getting speakers for my Formula and it seems everyone has been going with the Infinity Kappa 62.9i speakers. I have the component style speaker grills on my doors that look like they can take the seperate tweeter as compared to the 62.9i having the tweeter mounted on the midrange. I am interested in using the 60.9cs seperates and wanted to know if the tweeter will fit in that opening or not.

I will doing a complete rewiring as the previous owner had a custom stereo wired in and removed all the OE wiring for it as well as removing the custom stereo before I bought it. I will also be using a custom built box that fits in the drivers side cubby in the hatch as well as a set of Infinity speakers in the rear sails. I have a Pioneer DEH-P47DH which is the Din and Half for the factory GM opening.

Any ideas on this setup or things I need to watch for.

I was also looking at going with the Infinity Perfect 6.1. This is more expensive and I am not sure how much depth I have to play with either.
