Reply to Is it possible to connect a 5.1 multimedia speaker system to a Hercules Rmx?

I have been believeing about getting some new speakers as I don't believe my PC system will connect via the sound card on my Hercules Rmx but I thought I would ask on here first unless there is a way.

Here is a photo of the back of the sub unit.

I am fairly confident there is no way to connect these other than via 5.1 PC sound card but let me know of any ideas?
