new install sugestions 93 mustang hatch

[aimone 4]

ok so i've currently got a single RF power HX2 15 on a saz1500. problem #1 its got a blown coil, problem #2 its currently in a sealed box im pretty sure is to damn small. the reason for the small sealed is i had to work with the wood i had layin around to make it fit so i could use my back seat. previous box was 4ft^3 ported tuned at 33hz. now im almost certain i dont have room back there for 4 cubes ported if i reconed the sub with upgraded coil and suspension. so im asking you guys for suggestions on a setup that will get loud, low, and move some air while sounding good in the cargo area of the 93 mustang. still plan on using the saz1500. been looking at and liking the skar 12's. but also loving the thought of a couple sa-8's cause there "cute" and do work. any ideas or recommendations would be much appreciated. especially if anyone has experience with this model stang.

also been thinkin wall it behind the rear seats with a couple 15's or something. ill get measurements of the whole hatch area on my lunch break if that helps

SA-8s are adorable. However, if youre looking for loud and low you have better options such as a Bl 12 or any other similar drivers.
