Confused on should I Bi-Wire or Bi-Amp??

I have the speaker cable. Found a pair of Tellurium Q cables. But I need a balanced adapter cable. I'm going to see my dealer tomorrow I'm looking to get the Tributaries 4ft 4 aby-fmm. Should be interesting when I can get full use of my amp.

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. 

Yes op if you want to biamp a center speaker. You need two power amps or rails from the same amp. 2,3,4,5, etc. 

Some amps have a mono/stereo input switch. Some bridge the two rails for a single output and double the power (YUK)

Install a RCA/XLR splitter (if you don't have a mono input switch) and input the center signal (from the preamp/AV/HT unit) to both L/R inputs on the power amp. Then remove the jumpers at the speakers and use TWO sets of speaker cables. L/R to the top/bottom on the speaker and the same for the remaining R/L speaker cable it goes to the bottom/top.

Have fun.

Regards

I would hook up the posts for left and right channels as if it's a normal pair of loudspeakers.
