Connecting an integrated amp to a power amp and EQ :

I have an old Pioneer SA-600 integrated amp (19 wpc) and want to hook up a power amp and an EQ. The Pioneer has main and pre jacks plus a switch that says: Separated / intercoupled. The power amp is 75 wpc and has only input jacks and connections for speakers. How should I connect these two components to the SA-600 ? I guess you could call this a poor man's attempt at high end. I would greatly appreciate some advice ... Thanks
Using interconnects of choice hook the integrated amps Pre out RCAs to the amp inputs. Select 'Seperated' with the switch.
