Link PC to system?

In our family, a subwoofer for a 5.1 system will soon be dropping out (Teufel Columa 300 Easy 5.1 Set S) I wanted to ask whether you have any experience and whether I can somehow connect the said subwoofer to my laptop with a couple of speakers. The sub has a chinch exit. Is there something where I have 3 chinch inputs (each red + white) which I can then use on my laptop?

There's a jack to cinch adapter, but if it's just a subwoofer, you actually have to connect it to a system, otherwise you won't have the rest of the sound.

Kline chinch cable to 2 Y cable then once stereo in the sub and the others the amplifier for the other boxes but then the volume can only be controlled via the pc.

or if you have a 5.1 card inside you have windows aud 2.1 and work with 2 jack chinch cables
