Once you go Bose, it's hard to get out. Lesson learned.
Connect the 2 rca plugs from the acoustimass to front left/right line level out on your receiver. Wire the speakers (I presume you have 5 cube pairs) from the Yamaha speaker outputs directly to the cubes. Set the speaker size to small.
Eventually, bail out of the acoustimass sub and get a regular sub and use the LFE output from the receiver. Sell the acoustimass on EBay. Someone will buy it.
