1 sa15 ported or 2 e15s sealed up?

[AudioMan4Life]

I have read through a lot of other posts on one sa vs two E series but not with the Es sealed up . . I have a ford fusion not the biggest trunk i can fit a single 15 enclosure at the 3.5 cubes these sundowns need but the only way i can do two is sealed . . Would i be better off with an sa ported or two Es sealed . . Also 1.75 per sub enough sealed?
