Not much info on the inputs on the Newgg site, but from the low rez photos it looks like there are two pairs of line-level RCA inputs on the sub: one set for the front satellite speakers and another for the back speakers. You should be able to plug a line-level RCA interconnect into either pair of RCA inputs and get sound out of the two front speakers or the two back speakers, depending on which pair you plug into (or a 1/8" stereo mini > stereo RCA cable, from a headphone jack out). If you connect both of the left inputs together with an RCA 'Y' cable and both right inputs together with another one, you should get sound from all four satellites.
