That's generally the problem with subs, sealed or ported, a given cone volume requires a fixed space. The secret is in finding an unused space into which you can throw an appropriate enclosure. Have been looking around my 2015 trying to find room to stuff a 4x 8" sealed setup. No dice so far. Best I can figure is directly behind the rear seat firing up at the rear window. Amp under the rear driver side seat maybe. Lose maybe 2-3 cf in the rear cargo area. But I'd gain back the foot and a half in the floor! After watching a bunch of jeep videos the only thing I see consistently hauled in there is mud...
