I have the Outlaw Audio model M8 Powered Subwoofer. When Connecting to a System with No Preamp Outputs the manual shows the speaker outputs on the power amp connected to the speaker inputs on the sub. I assume the next step is to connect the speakers to the speaker outputs on the sub although this part was not stated. As an alternative I would like to do it different way. Could the speakers be connected to the power amp as normally done and the sub connection made by running a second set of speaker wires from the speaker in on the sub to the speaker outs on the power amp (or to the speakers themselves as that is the same signal). There would be no need to use the speaker out on the sub at all?
