The Kicker speakers may have been different, but my Roswell can's had Kenwood speakers, and the holes had to be cut out. It was simple though, I used a jigsaw and was done in 10 minutes.

The 650's require more power, having a larger magnet. The SS-65's, are a little cheaper, but are basically the same speaker with a smaller magnet so they'll require less power. Both are great speakers.
