Onkyo as 2nd amp

I have been Onkyo Sr607 running at 7.1 with all seven speakers hooked up for the surround-sound. On the 607’s sub woofer output I am running to a Onkyo sr606 with bi amping capability. I plan to run four 10 inch 8 ohm subwoofers, 2 to the front left and right and two to the bi-amp outputs left and right.
My question is would the 606 drive all 4 with equal power? Does it matter if I even use the bi-amp or can I simply use any other channel for that matter?

    Let me see if I understand you correctly. You have one AVR connected to another via the sub out and want to know if you can drive 4 subs with the second AVR?

    I'm trying to wrap me head around that, but my instinctive reaction would be no.

    Gotta use the right tool for the job, and an AVR's amplifier doesn't seem like the right tool to drive subwoofers.

    I tend to agree that this wouldn't work.

    Since you are looking to just power the subs you don't need a super expensive amplifier(s)...

    Without thinking too hard about this:

    1) why not use powered subwoofers?
    2) you (the OP) might want to do some Googling/reading about distributed bass applications.

    I don't think it will work, but saying that your home theater has 4 subs might sound cool to your friends. :p

    Even if you can, it doesn’t mean you should. How big is your room? What kind of subs are they, and what type of enclosure?
  • I built 4 transmission line speaker boxes for the four Kicker CompVr's.... the room is almost a thousand square feet and plan to put one sub in each corner of the room. Each box is 48 in tall 18 in deep and 12in wide. I built the boxes at the perfect resonating frequency for the subs.
  • That distributed bass thread was very informative. However why was the polarity on one of the subs switched?
