Have a onkyo txnr 709 powering my 5.1 b&w and polk combo and have been considering running adcom, rotel, nad, or carver 60w+ used amps(music only) for 2nd room preouts to run the 901's(VI) located in my 12x12 bedroom. my question is do i need a input and output on the amp to use the bose eq? also any thoughts on these brands would be appreciated
