Adding stock sub to Bose system that didn’t come with one from factory?

[Pstaples18]

I know the subwoofer talk and Bose subject has been beaten to death but I can’t find my answer. I have a 2016 Sierra Denali (not the ultimate) and it has the Bose system but I’d like to just have the factory sub that the ultimate package has. I don’t wanna lose my under seat storage and I know it’s not the best quality sub out there but just a little more punch from a sub will be fine for me so the center console stock one would be fine if it would work. 
 

Will it plug and play being that I have a Bose system already? Do I need to buy a new center console? And does anyone know where I can get what I need assuming it would work?

 

Thanks

Your 2016 Denali already has a subwoofer in the center console.
