Help with hooking up a Powered sub to a PA system

So I have the following question....Im a total noob, so please excuse my ignorance. I have a Behringer PA system and a powered sub from Rockville and wanted to know how the heck I connect it to the system. I have attached pics of all the backs of the equipment I have, so you guys can see what Im working with. Any help will be greatly appreciated.

The only way you could do it is by connecting the RCA booth outputs from your numark controller to the sub.

Why use the booth out??? Why not use the Numark Master Out to the Rockville sub, then go to the input of your Behringer PA system from the outputs of the Rockville sub?

To have separate level controls.

Ah... OK... That would work. But of course you lose your monitors (if you use them).

Hadn't considered that but it's an interesting option, I do see one downside though.. the sub output is going to be mono. It's also unclear if that output is simply wired in parallel with the input(most likely) or if it is post crossover filter which would be good but not as likely.
