easy fix. Just need a jigsaw and some 1/4 or 1/2 wood. Get the speakers and see how much the speakers need to be raised. There shouldnt be an issue with the 6x9's because there is nothing behind them. I run about the deepest speakers I have ever seen someone put in a door in a stock location. I use a 1" riser ring and they fit fine. So just get the speakers you want and you can make them fit.
