Trying to create a surround sound system using 2 different speaker systems

[YouthPcEnthusiast]

Hello. I want to have a 7.1 speaker system, but I don't want to break the bank for 1 set with an audio receiver. I want to be able to plug it into my computer's audio jack. So, I was wondering if I could combine these 2 Logitech sound systems into one to have a 7.1 setup.

I have a sound card, which gives me a 4 audio jacks: Pink, green, orange, and black.

Is combining these 2 speaker systems possible? I read online that plugging 1 system into the green port and the other system into the black port to make it work. Is this possible?

It should work. Try it and when you find out let us know.

I'll be buying these 2 speaker systems in a week, so I'll tell you then.

Is there any possible way to add a 3rd, separate speaker system or single speaker to the previous 2, Such as a tweeter?
