yes! i'm confused, what i want to do is connect two kenwood amplifiers together, the first amp is the ka-8100, and the second is the ka-6100, they both have pre outs and in's so is it possible to connect them, i thought all receivers and integrated amplifiers had a pre amp side, i want to use the ka- 6100 for my rear speakers, and the ka- 8100 for my front speakers, i don't have a power amplifier and then a pre amp to connect, these are two integrated amplifiers that i'm trying to use together, can this be done?
