Question New home - How to connect tv to ceiling speakers?

Aug 4, 2021
Just moved into a new place and have speakers in the ceiling. I have a connection box on the wall with 2 plugs each for left surround, left, center, right, right surround, l back surround, and r back surround. There are also 2 plugs marked sub 1 and sub 2. (I would attach a photo here, but not sure how to.) What do I need to purchase to connect smart tv?
