How much power does an amplifier use?
The average electrical consumption per hour of an amplifier is 100 to 200 watts. To put that into perspective, they use a similar amount of electricity as a refrigerator, slightly more than lights on the ceiling, and ten times less than a standard air conditioner.
How do you calculate RMS on an amp?
RMS Power: When measuring a pure sine wave, RMS voltage can be calculated by measuring the peak voltage level and multiplying it by 0.707. This value can then be used to calculate RMS power.
How do you determine the wattage of an amp?
Watts = Amps x Volts
- 10 Amps x 120 Volts = 1200 Watts.
- 5 Amps x 240 Volts = 1200 Watts.
How are amplifiers rated?
The power rating for an amplifier is measured in watts per channel. An amp that is measured, for example, at 100 watts per channel at 0.02 percent THD (total harmonic distortion, the standard measurement) is quieter and is probably more powerful than one that is measured at 100 watts per channel at 0.2 percent THD.
How many amps does a 1200 watt amplifier draw?

How many watts does a stereo system use?
Most times, the wattage is low, somewhere around 8 to 10 watts RMS per chanel. To find out the power of your head unit, type in the make and model to google search. Most standard factory car stereos usually have no more than about 10 watts RMS maximum output power per channel.
How is stereo wattage calculated?
You would need to clamp your power wire to determine the Amperage draw and the exact Voltage under load. Then figure in efficiency. Your cars Voltage x the Amperage draw x amps efficiency = Watts.
