I have no fargin' idea what you're talking about.
Really? Don't worry...I know exactly what he's talking about.
Welcome to the forum, Albert! Yes, you can run that speaker set from the Marantz. You would connect the smaller speakers directly to the speaker terminals on the Marantz (so, don't connect them to the sub). In addition, you'd connect the subwoofer output on the Marantz to an RCA splitter, and then connect both ends of the splitter to one of the analog inputs on the Onkyo sub. You'd select that input on the Onkyo, and you'd adjust the volume on the Onkyo as if it were a powered subwoofer - in other words, set the volume, run the Marantz auto setup routine, and only adjust the volume on the Onkyo again if the Marantz says to.
Let me know if you have any questions about that.
