Well, I've wanted a better sound system in my room for a long time now. I was thinking for a while and realized we have a set of desktop speakers not being used that sound excellent. Currently, I have a gaming chair that as two speakers in the back. So that takes up my two RCA ports in my TV. So I went to radioshack and found a couple adapters that fixed me up. The desktop speakers went to a 1/8th stereo jack. I found an adapter that splits one RCA port into two, then bought another adapter that converted it to a stereo jack. I hooked all of the speakers and subwoofer up, and whala! Works like a charm and sounds great.

(Yes, the speaker on the left has a rubber band on it. There's a small problem with it, but instead of tearing it apart, that fixes it for now)
