Just use a set of ECX690 (Energy series 6x9) if you want to upgrade from your stock BA. They run about $200/pr and will do fine plus be easy to install. You don't need much rear anyway. Focus on the front. This is unless you want to get trick and relocate a second pair of 6 1/2" coax drivers to the side wall rear panels. This option works WAY better but is a little involved.
