I have some install photos, will post here shortly but some notes right quick: Woox fits under passenger seat, just barely clearing the air-bag sensor components. The wOOx sounds much tighter firing into the floor than up at the seat, and I think a bit of work on a more solid mounting solution would help even more. It's a very easy install, only tricky bit is the grounding point, and conveniently there is an unused 6mm nut welded inside the passenger doorsill for this. Again, I've got photos of all this (except the HU wiring, sorry).
Truths about the wOOx: you will not rattle the neighbors windows, turn heads with boom in the shopping-mall parking lot, cause body panels to come loose, remove clothing from your passengers, etc. You sure as hell will not win any sound-pressure-level contests.
However, as the least-invasive way to bring out the low-range in your music, the wOOx is the best compromise. It sounds tight when kept within its range, though I find I use the remote to tune the levels a fair bit, so I'd recommend keeping it handy (fits perfectly into the slot next to the shifter).
OTOH, the Basslink sounded damn good to me, and proper subs in boxes with good amps obviously even better... but with a stroller and other baby stuff in the hatch, I simply didn't have the room for them.
