you wont know how it sounds till its in the door. Most of the times software projection and real world results vary GREATLY so fk it, pop in the flutes, the sonys the kenwood, whatever you want in and see what works best off the bat then do tuning afterwards. Too many factors in a car door's shape, thickness and over design, your dash shape, seat and head liner fabric and everything else to rely on graphs. Only graphs you can rely on is measurements after the drivers are inside and playing and you RTA(do before you tune and save the graph) it. Once you RTA it, you can compare to the driver's projected response and compare it to your in car response.
then in the future you can pick drivers that match your vehicle acoustics better now that you have an actual baseline in car response.
