How To Wire 6 Speakers How Do I Wire My Speakers/ Sub?

How do I wire my speakers/ sub? - how to wire 6 speakers

I have Logitech X-530 speakers. These speakers are designed to be used as a set and a connection to the computer. They are 5.1 (6 channels). Each chamber is connected to the sub via RCA's and the secondary is to the power connector. The entry for the speakers / sub CVR is 3x 3.5 mm audio connected to the submarine.
I believe my an AV receiver / amplifier + 6 speakers Products Fair - Port Cable (for each channel in a cable and cable + to -)

Terminals = output cable receiver ordinary 6-channel speakers.
Access to the speakers & sub = 3 ports 3.5-mm-CVR

My question is, how can I wire this? I am ready to weld and to my own connections.
CVR-1 port supports 2 channels? How so? - If the C 2ANNALS came into the plug? - Where do these come meet the speaker wire terminals? And it is safe to connect speakers and sub to a receiver?

Any help would be very grateful. I am certainly not an audiophile, and I am only a beginner sound so thanks for your help.
