4 ohms
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 formula for watts is, Watts = Amps x Volts.
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".
A typical microwave is 750-800 watts. There are lower (and higher) power machines, but the 'normal' for general use is 750-800 watts.
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.
Speakers are measured in Ohms not Watts. Watts is the amount of power you will be supplying to the speakers. In my 2009 Corolla the speakers can handle at least 400 Watts as this is what my OEM JBL system is pushing.
