I sent a bunch of pictures to Bavsounds and they, as I, were surprised that there are absolutely no subwoofers in the HK system, so this is pretty much what they offer for an upgraded sound stage.

The subs are the lower speakers behind the seats as opposed to underneath the seats as normal.
They use the enclosure between the rear board and the trunk board as a "sub box", but it's so badly dampened, it just causes the trunk to resonate on low mids and rattle like a collection jar.
They're also a total pain to access to swap out and dampen. I'm planning on dampening it properly when I have enough time. Probably at the same time I do the amp swap.
