I am now ready to connect the two 2200's I just received. I intend to use them to power two mini-stratas in a two channel mode. Currently there are a left, right, center and two rear surround speakers connected to the the 7500 which in turn is connected to the 990 via balanced cables. The question is should I connect the 2200 to the left and right channel of the 990 and then utillize the left/right surround channels for the existing speakers? I have read Gonks article on the 200 and researched how to use trigger 1 & 2, I am just not sure where the balanced cable should go from the 2200 to the 990.
