I have this issue with a subwoofer - coupled with a bad amplifier/grounding/(something?) it creates an immense WOOOOF every time it turns on and off. This causes my house to shake 15 minutes after I go to bed, just as I'm about to fall asleep. Have definitely considered auto-starting something that played a continuous low tone to prevent it from happening.
