How to connect passive speakers to xbox one?


Sep 14, 2009
I have an old pair of audioengine A5 powered speakers which I am converting to passive because the internal amp blew out. Once I convert them to passive I wish to connect them to my xbox one and I am trying to figure out the best way to do this. I was thinking connecting via the optical cable, however I am unsure of how to power the speakers. I would like to avoid getting an expensive receiver and just need something to power these two desktop speakers and connect them to the optical port. I am new to all of this so any help would be greatly appreciated. Here is a link to the speakers I have (pre converted to passive).
