sounds to me like it's beggin for a set of 4 6.5 inch Focals, maybe 600w diamond amp with a single 12 diamond sub, and a 1000w diamond amp on that.... 6x9's up front? ewww. I'd consider leaving em in the back. Just as soon shut down the ones in the dashboard and mount the separates from the 6.5 focals up near the side mirrors. Wonder if anyone has a wiring diagram out on these yet...
