PC speakers on AMP

[Rex-Hyperfly]

Hey guys i've got a question:

I have my pc hooked up to my amp: https://www.google.sn/search?q=sony+str-k780+connectors&biw=1445&bih=737&source=lnms&sa=X&ved=0CAUQ_AUoAGoVChMItNu5172DxwIVhrcUCh2TvQ4a&dpr=1#q=sony+str-k780+

And have 5.1 home cinema speakers hooked up to it : https://www.google.sn/search?q=sony+str-k780+connectors&biw=1445&bih=737&source=lnms&sa=X&ved=0CAUQ_AUoAGoVChMItNu5172DxwIVhrcUCh2TvQ4a&dpr=1#q=lg+ht806th

And this subwoofer : https://www.google.sn/search?q=sony+str-k780+connectors&biw=1445&bih=737&source=lnms&sa=X&ved=0CAUQ_AUoAGoVChMItNu5172DxwIVhrcUCh2TvQ4a&dpr=1#q=yamaha+yst-sw012

I use them with my tv (hooked to the pc)

But i'm going to buy speakers for my desk and i was wondering if i could use two 2.0 speaker systems in 5.1 by hooking them to the amp and using my sub.

How would i be able to do that?

Would Jack to RCA connectors help?

Also how would i switch on the amp i mean switch from home theater speakers to pc speakers
