I did get your pm but as I have just got home at 1:00 am I am without time and energy to respond to your pm. I am sorry as I am really busy at work. The jbl amp will work fine to run the fronts and i think we should start with that first and you can decide if that is enough for you. Does your amp have electronic crossovers in it? Your best bet for the woofers is woofers not coax's. As far as speaker harnesses I don't usually use the harnesses so I would recomend running new wire into the doors.
