Question How to run sub independently

[mphill0333]

hey all,
i currently have a pair of edifier R980T speakers and have come across a Logitech z623 SUB ONLY.
does anyone know of a way that i can connect this system upto my pc so i have both the logitech sub running and the two edifiers?
Cheers

That sub is designed to be used with the volume control of the speakers connected to it, so no you can't just use it with only the sub, no volume control.
