I just got the Pioneer HTZ-BD51 in the mail, and I was trying to set it up. Through a lot of complicated wiring, we got the front 3 speakers working (center, front left, front right) However, there was no speaker wire for the subwoofer, and it wasn't wired to the reciever. Do I need the speaker wire to get the sound out of it? I KNOW I have the speaker wire situated right, and I know the speakers work... its just getting sound out of them. Also, what kind of speaker wire would I need?
