I am been looking in different forums to try and find the answer for this but to no avail. I have a Denon 3803, Marantz mm9000(150w*5),Polk rti150's, csi5, fxi5's, and an SVS pb2+ on the way. I am curently using the Denon as a preamp for the fronts and the Marantz biamping them for a total of 300w per tower. So, can I use the Denon to add more juce to the woofers of the towers by running cable from the speaker outputs of the Denon to the lower binding posts along with the output from the Merantz amp? Or is this just crazy talk...
