how many watts does my sound system use?

it's rated at 190 watts, but I generally keep the volume under half, so how many watts does that actually translate to?, in general terms I cant find that info, I'm sure efficiency interferes with a 1-1 ratio, so what are the ratio's at, say, 1/4,1/3, and 1/2?

I'm talking about actual electricity use, so I have something to tell my roommate.

    It is hard to say for sure. Watts in terms of amplification may not translate directly to power usage at the plug. If you want to know for sure, buy a Kill-a-Watt meter. This will measure the actual usage at the plug from anything. It is an incredible money saving gadget that costs about $20. It could save you that right away if your roommate demands more money for all your electronics.

    See link below for Kill-a-watt details. You can buy one from Amazon for $19.99.

    How much gas does your car use?

    Is it different on the freeway, in town or sitting at the curb?

    The answer is: it depends on what it is doing at the time.

    Your speakers consume about 5-7 watts on average over the course of a movie. But to increase the sound 1 db, you must double the power. So volume swings consume peaks of power. This is why your system is rated to numbers like 190 watts.
