Hi everyone. I just bought this low tech home theater and am having trouble setting it up. I have all the speakers connected to the sub woofer. What I do not understand is how to get sound going through the front, center, and back speakers all at once. On the back of the sub there are left/right audio inputs for all three speakers. The instruction manual says to connect the cables from this point, to the back of the dvd player. The problem is that I dont have three different outputs for audio on my dvd player or tv set. All three sets of speakers work individually. Can anyone help me out?
