You can run the subs in isobaric and it'll save a ton of space, but will require measuring for depth(front to back) and either a custom box or a standalone isobaric assembly(made from pvc/acrylic tubing).
Depending on height availability, you could also mount with outer sub pointing towards driver's side of truck.
