You could bi-amp your center channel speaker just to use your other amp channel and you would get more headroom and likely more volume and clarity. I personally have never done that with a center. I've been bi and tri-amping my stereo mains for 40+ years.
Confused on should I Bi-Wire or Bi-Amp??
I have a Forte 6 stereo amp hooked up to my Aerial CC-3 center speaker. I',m only using just one side of the amp. If I want to use both sides do I hook up the other speaker inputs in regular fashion or connect the top end w/the right side output and the power of the left outputs to the bottom end and take off the brass connections. The amp is rated at 200 wpc and 350 at 4 ohms.
