I’m getting ready to implement this upgrade as well, after speaking with Fo! Picked up the same woofer for a good deal and already have a JL 500/1 mono block laying around. Waiting for my cabling and polyfil to come and will try it out. To counter the bass roll off from the B&O I am going to employee this Audio Control unit. It will address this.

This won’t sound anything like two 10” subs or let alone one 10”. But it’s a pretty cheap and simple upgrade and lets you keep all your floor space and no mods required behind the seat. If it sounds pretty good then I will roll with it for at least a good long while. If it doesn’t, I will go with a single 10” at the very least. Was looking to upgrade the whole system, but may piece meal it along the way.
