If you do that with a conventional amplifier, the result will be each of its outputs will be mono. If you do it with a balanced (differential) amplifier, you'll likely send the amp into self-destruct mode.

krIf the speaker supports biwiring, it will send one input to the woofer and the other to the mid/tweeter.
No, you're thinking of biamping. Biwiring sends the same signal to each. They are two different things.
Cleeds, yes, biwiring sends the same signal to each input of the speaker, from the amp, but that’s not what Kal (kr4) was referring to. He was saying, correctly, that "it [the speaker] will send one input to the woofer and the other to the mid/tweeter." And his subsequent sentences were also correct.
To the OP, I’m not sure exactly what connection configuration you were envisioning between the amps and the four terminals on the speaker, but none will work correctly, and many will risk either blown fuses, self-protective shutdowns of the amps, or damaged amps.
Not a good idea, as Kal indicated. Regards,
If you want L-C-R or L-R to the center, get a quality passive soundbar such as one of the two GoldenEar SuperCinema 3D models (http://www.goldenear.com/products/supercinema3d) and connect the amplifier outputs to the appropriate soundbar inputs. I’ve heard it and it’s really good, esp. if you add a GoldenEar sub.
Doing it the way you propose will give you a very unsatisfactrory sound--low frequencies from one channel and high frequencies to the other sent to the center. Depending on the sound mix of the source, it may work OK on some shows but be unintelligible on others.
You do not want the left and right information in the center. There are 3 speakers up front for a reason - to separate the sound into a more realistic sound.
Think about an explosion that only occurs in the left channel. If you wire the left channel to the tweeter and the right channel to the woofers, you end up the explosion going to the tweeter and and nothing going to the woofers. So, you get just the high frequency part of the explosion in the center. And remember the center usually does not have as good base response as your main speakers. Plus, you would miss all the center speaker information.
Bi-wiring is there to bypass the crossover in the speaker, nothing more.
It would be very unusual for it to be wired that way. Biware speakers are usually wired so one set of terminals go to the tweeter and one set goes to the woofer(s).
Why are you trying to do this? Are you trying to not use left and right speakers? If so, you could probably do that by telling the receiver you have no left or right speaker, but you are going to get basically3 channels of signal coming out as mono coming fromthe center. Is that what you want? Its really hard to see what advantage you are trying to gain.
