Hi all.
I am trying to calculate how much power consumption my HT and related components draw during use. I am simply using the stats in the manuals for my various pieces. For example, my TV's manual says Max power consumption is 200 watts. However, my subwoofer manual does not give a power consumption figure. If my subwoofer is a 300 watt RMS powered subwoofer, is that also the "power consumption" figure I should use in making this calculation. I am trying to figure out how much load I have on my circuit (approximately, with max useage). it is a polk psw505.
It is a 15 amp circuit and 120 volts....does that make its capacity 1,800 watts?
anyway, if anyone can help with the subwoofer power consumption question and check my math above, i'd really appreciate it. i was a liberal arts major
