I have another question. I was talking to someone today about it to see if they knew, and he said the sub would have to be "self powered". Is this true? What I mean is, does the receiver just send the signal or is it actually powering the sub too? I found a computer sub to see if that would work because it is powered and I couldn't get that to work. I don't understand why it's so difficult (you all probably think it's a breeze

) to hook up a subwoofer, but everything else is so simple. Basically, my sad setup is I spliced my subwoofer with the center speaker....I don't think that's even providing any extra bass, but it is in dire need of it. It sounds amazing other than the lack of bass
