Running them bridged/mono over one stereo integrated adds...one piece to the system (2nd amp). Not nearly as death-defying as it sounds. In fact, bridged/mono integrateds use two less interconnects than using pre and amp. Don't let the fancy terminology fool ya. No more complicated than trying to set up separate preamp and amp. On the Classic One, all I needed do was flip one switch to make them mono. Ughhh! Tough.
Left cd out goes to left amp, to left speaker.
Right cd out goes to right amp, to right speaker.
It's THAT simple. Well, almost. ;) You just have to connect everything right on the speaker connections or you blow it all up! Lost my first house that way! ;)
And then, if you want to run a sub with it, you gotta biwire each mono amp...yeah, second thought, go get a Bose. Glad I could be of help. LOL
