i have a stereo, but i do not know how many watts it is. it says on the back that has 230 watts (rated power) now is that how many watts it takes to power it, or is that how many watts it puts out?

Total output power

Although the calculations the ME are correct, on the back of the amp or receiver, the stated wattage is usually the power requirements of the unit. If you don't have the owner's manual, Sometimes an indication of the output wattage is in the model identification (1100= 110 watts). The best way is to Google the brand name and model number. I buy a bunch of audio amplifiers and receivers at flea markets and resell them on Ebay. This is the way I find out about them so I can write up a decent description. High power (100w and over) also usually have big can type capacitors.

If it really says " 230 watts rated power ", that should mean it is a 115 watt per channel unit. The thing you never know (due manufactures some times cheat) is if they mean real power or rms power. The clue is the statement " rated power ". Devise power (fused power consumption) is not normally listed as "rated power".

the total truth:
those are musical watts, total possible power, which are calculated by multiplying voltage by electrical amperage to flow trough the speakers so the manufacturers use their top peak values, now, the method to obtain RMS Watts, which is the one that matters is to divide that number by 1.4142 which is the square root of 2, why? just believe me on this one. so a 230 Watt amp will actually as162 RMS Watts
