Has anyone put in an aftermarket woofer under the helm of a Mojo? Did you have sufficient room to build and mount a box? For a 12" woofer?

My 2013 is in the factory now, expecting delivery early April (woo hoo!). I'm putting in Wet Sounds all around and my plan (so far) is to put a 12" woofer under the helm where the factory woofer would be. But looking at the demo boat at my dealer (no woofer in it), there's a bit a cabling under there that to me (audio ignorant) would seem to be in the way and prevent installing a proper woofer enclosure.

Thoughts? Advise? Anyone skinned this cat already? I'd really appreciate any info ya'all might have!
