So I'm about ready to get some new speakers for my computer now, (and possibly for later use on a personal entertainment area) yet I'm having some trouble figuring what cables would be appropriate. The speaker system is http://www.amazon.com/Audio-EXMS581-Surround-Speakers-System/dp/B00ALXZGIM/ref=zg_bs_tab_pd_bsnr_1 from a company that does have history, yet searching for reviews comes up short(I'm still optimistic that they will sound great for the money). With this I am also looking to purchase http://www.amazon.com/Creative-Soundblaster-Surround-System-SB1095/dp/B0044DEDCA/ref=cm_cd_ql_qh_dp_t as my current computer has a relatively old/useless sound card. Unfortunately, the speaker system has only RCA connections, so what I think I need is a RCA to RCA (front), RCA to "rear" (rear/side), RCA to "center/sub" (center and sub). However I cannot find a cable specific to RCA to rear or RCA to c/sub. So my question is: are the "rear" and "c/sub" connections specific (where can I find these?), or could a RCA to 3.5mm be used in place?
If you have any other system setups you would recommend I would be happy to hear them, but please keep in mind that I'm going for a <$200 setup.
