4-way component setup staging help

[Nothingface5384]

I'm ditching the 6.5 front in door and 6x9 coaxials in favor for a front fill only setup.
I havent decided out what brand as of yet.. but for the most part it'll be something like this..

2 way component set...6.5 woofer in kicker with 1in tweeter in A-pillar
either a 3 or 4 inch Mid-Range under my window door crank(6.5 coaxial currently resides there)
then a 6.5 Mid-bass at edge of door pretty much hip level of occupants.

or should place mid-bass under window crank as I already have 6.5 speakers there then move the 3 or 4in mid-range by tweeter or in kick panel with 6.5woofer?



also is it a big deal the mid-bass(mid-woofer) is same size as woofer? should I jump woofer to an 8in

rear fill will most likely be just a single Sundown SA8 sub, but may jump to a SA10
