Is there a correct way to connect these speakers to a PC?

This might expose me as a zoomer, but what's the proper way to connect these jacks? Both the black and red ones seem to output to the subwoofer while the green outputs to the speakers.

If you have a desktop PC, you should find colored plug for these on the back

Usually, Green = Speaker, Red/Pink = Microphone.

It was gifted to me by a family friend who had it lying around so I don't know the exact set, but it looks something like this one, just not surround so without two of the front speakers and the wide short speaker https://www.store.refurbit.co.uk/product/creative-subwoofer-surround-sound-speakers-system-inspire-p5800/

You mean your is a 2.1 ?

2.1 = Two speaker + Subwoofer

5.1 = Five speaker + Subwoofer

lmao yeah that's a better way to put it

If you simply plug the green one, the subwoofer does not work at all ?

[civic haven]

It actually does and I somehow hadn't noticed it

[solid plaza]

It would have be very unusual... 2.1 speakers systems usually does not have separate subwoofer jack, it filter from the standard stereo input.

However I can't tell you what the other jack are really used for without more details or sound system exact model

I think it's odd that they both output to the subwoofer
