This is a good set up. Echo upgrading to 6.5 in in the front knee panels and sound bar. I went slightly cheaper kit with Rockford amp / speakers. My goal was to be able to hear audio with the door off. With a Rockford Fosgate R2-500X4 (similar speaker watts as OP JL) I have full audio near 60% volume level. No doubt the system is door-off worthy.
