Am I right to assume there are four 10-amp channels/circuits contained in one unit? Can you use the average 15 or 20 amp outlet in a bedroom? If this was any other electrical equipment I would think it would take a 50-amp breaker of it's own. I realize the voltage is not the same. I just don't see any referrence in the manual. If you divide the total available of 620 Watts by 120v, you get 5.16 amps. If you divide 620w by 18v you get 34.4 amps, so I'm missing something. Keep in mind I'm someone that thinks I've accomplished something if I get the left and right speakers hooked up correctly.
