Regarding how to hook up a center channel speaker with fader control adjustment: My HU has front, rear, and sub pre outs for the amp. Hook the front pre outs to the components and use the rear speaker level leads directly to the center speaker. You run left rear negative and right rear positive (or left rear positive and right rear negative, it doesn't matter). This way if you run your fader full front, its all components and if you dial it to full rear, its all center channel. This allows you to dial in the fill as needed. This obviously only works if you are not running rear speakers.
