I've posted this before, but apparently i've used a censored link/source i had no idea. I bought a pair of Edifier R1280T powered bookshelf PC speakers, and a used Canton AS10 subwoofer. I'd like to get 2.1 working with this setup, the edifier R1280T has 2 additional RCA Line-In inputs and my subwoofer does too with 4x speaker wire inputs. Is there anyway to get this to work on PC? i don't need an AMP cause these already have amps inside them.
