Do you have the FPS2000 which has 4 satellite speaker and a subwoofer?
This system requires the sub so if you just have the 4 sats you would need at least an amplifier or av receiver to drive them.
If you have the sub you can use the front and rear analog inputs to drive the sub and speakers. You would not get surround sound unless you had these outputs on your source. You could connect any stereo source with analog output to one or both to get multi speaker stereo.
It can probably be hooked to Blu-Ray players, you wuold need an adapter to hook it to PS4 or Xbox One, anyway where do you want to hook it to? And can you tell me the full name of the speakers system you have?
