Was MC using the JL 7.7" in 06? If not, I don't think they will fit but I could be wrong. I have a buddy who has a 04 XSTAR that had some clarion components in the factory cans. We pulled them out and installed the Wet Sounds XS-650's. They fit perfectly and sound great. They are not a HLCD so they will prob not do it for you by themselves. He has 4 of them and a Wet Sounds Pro485. That set up wouldn't be much more than the Bullet speakers (can't tell if they are $699ea or a pair, especially if you found a PRO485 used, though you would need more amplification.
