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 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 power in watts is equal to the volts times the amps so that is 120 x 7.5.
The Orion CS 100.2 amp is rated for 100 watts RMS per channel at 2 ohms.
75 x 1 Watts RMS @ 4 Ohms 150 x 1 Watts RMS @ 2 Ohms
Ohms can be found by using these formulas. Ohms = Volts/Amps, Ohms = (Volts (squared))/Watts, Ohms = Watts/(Amps (squared)).
The normal calculations for watts are as follows.amps x volts = wattsvolts2 / ohms = wattsamps2 x ohms = wattsScroll down to the Related links and look at "Watts, Volts, Amperes, and Ohms".
There are three formulas that you can use. Amps = Volts/Ohms Amps = Watts/Volts Amps = sq root of Watts/Ohms
A typical microwave is 750-800 watts. There are lower (and higher) power machines, but the 'normal' for general use is 750-800 watts.

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
