I understand how optical/coax works - I figured everyone ran into this problem with PC speakers on a TV. I'm not going to mess with that convertor because of the external power requirement.
Couldn't I just use this and run them through the RCA jacks?

Are you just testing them before sale? Because if you are, a 3.5mm cable to your phone will do just as good.
I do not see any analog out.
I honestly see no way to use those on your TV without an adapter. Maybe somebody else here will know of something though.
