Range Rover Sport Subwoofer

Does anyone have experience with adding a sub in a 2009-2013 Range Rover? I'd like to keep factory look as much as possible take up as little room as possible I was thinking having it an enclosure built in the driver's side nook in the cargo area. Goal is SQ, not really looking for big hitting bass. The factory system is pitiful. I've got Morel Hybrid's 402's powered by a McIntosh MC404M and a JL 10W7-3 powered by JL HD750 in my 2013 BMW 550.

I'm looking for the same ball park in SQ. The RR has 3 way comps up front, so I'm leaning towards Morel Virtus 603's for the front powered by a Mac.
