Amp Hook up Question?

I have a Chiro C500 (5x140 into 8 ohms). Would like to double the power by purchasing a second C500 to hook up to the first for the 5 channels in my HT set up. Is this possible and how would I wire the 2 together? Your help and advise would be greatly appreciated. Thank you.

Are your speakers bi-wirable?
I don't think there is a good way for you to do this unless you have balanced outputs for all five channels. For balanced outputs, there is a unique way to use two amps. The idea was unique enough to be granted a patent on June 22, 1999. (Patent# 5,914,636)

Go here and read the short abstract and you will understand this method.
