I'm trying to utilize the bass module and cube speakers (5.1 setup) from a recently inherited Bose 900 Lifestyle 'theater in a box' system with a newer Yamaha amplifier but there is a control wire from the Bose front end receiver/CD player unit that plugs into the bass module for either volume control and/or to let the bass module know the receiver power is on/off. Is there a way to setup the bass module to work without this control wire or to create some kind of a jumper over this input into the bass module? I don't need the volume control functionality and can turn the system on/off manually if needed.
