To calculate the resistance in ohms, you also need to know the voltage. The formula to find the resistance in ohms is R = V^2 / P, where R is the resistance in ohms, V is the voltage, and P is the power in watts.

The Kicker Impulse 352xi amp has a maximum power output of 35 watts per channel x 2 channels at 4 ohms or 35 watts x 2 channels at 2 ohms.
The Urei 6250 power amplifier has a power output of 250 watts per channel into 8 ohms.
The power in watts is equal to the volts times the amps so that is 120 x 7.5.
The Sony XM752X amplifier can output up to 280 watts RMS per channel at 4 ohms, or 380 watts RMS per channel at 2 ohms, when both channels are driven with a 20Hz - 20kHz signal.
The Orion CS 100.2 amp is rated for 100 watts RMS per channel at 2 ohms.
Ohms can be found by using these formulas. Ohms = Volts/Amps, Ohms = (Volts (squared))/Watts, Ohms = Watts/(Amps (squared)).
There are three formulas that you can use. Amps = Volts/Ohms Amps = Watts/Volts Amps = sq root of Watts/Ohms
The wattage and ohms of a speaker are not related; the resistance for speakers is usually 4 or 8 ohms.
Watts = Volts / Ohms Watts = Volts x Amps
There is no valid conversion.
no you dont There are a couple of options. you can buy a 2 chanel with 400W rms per chanel, or a mono at 800w. make sure you match the ohms of you speakers with you amp. If your amp is 800w rms at 2ohm, it's 400w rms at 4 ohms. So if your speakers are 4 ohms, they wouldn't be getting the power they need. And remember you can blow speakers by under powering them, but not by over powering them.

A toaster operates typically at 800-1500 Watts. Therefore at any given moment of time the toaster will be generating this many watts while toasting.
That depends on the resistance (in ohms). We can't tell you the wattage without knowing that.
There are many different alternators on vehicles today -(and you haven't even told us WHAT vehicle). Most modern alternators can produce at least 800 watts, many up to 2,000 watts.
