You'd probably need to find a way to control the power to the Bose amp, such that it automatically powers up after the audio output becomes active (or above a certain threshold) and powers down as soon as it becomes inactive/silent.

Not sure if something like this might help:

Or you could build something from scratch.
I'd probably start by building something to 'sense' audio -- a simple Darlington Pair circuit might be sufficient, driving an LED so that you can visually check and adjust the sensitivity. Then you just need to use that to control a relay circuit, one with a delayed/adjustable on-delay.
