Hi. Im new to home theatre scene. I just want to know if I could connect a 5.1 speaker system with built-in AV receiver to a separate AV receiver. This is the problem... I have the Onkyo HTX-22HDX 5.1 (with built-in AVR in the sub) and I also have a Marantz AV receiver. I want the Marantz to be my AVR and just use the Onkyo as speakers and sub. Is this possible? If so, how do I do it?
