I should be getting my CDT HD642 golds in today. I got such a good deal I couldn't turn them down. All the reviews I have read say that CDT's sound pretty good off axis so mounting them in the stock location may work out and save some room for the other speakers. I don't mind butcher the car some since I plan on hanging onto it for long time. This isn't a bought and drive it for 2-3 years and trade it in car for me.
