Originally posted by Bryant The above picture shows that when the amp is "bridge-mono" it puts out more wattage at 8 or 4 ohm. Why is that?

because there is less resistance... the lower the resistance, the higher the power your amp can deliver. power = voltage ^2/resistance. the lower the resistance is the higher the higher the power, because voltage stays the same (127 volts for american household systems). since [voltage=current*resistance] and voltage is common, if the resistance lowers, the current rises, that's why we can't use the [power=current^2*resistance] without knowing the current.

bridged means you "bridge", or make work in conjunction, two channels that form a stereo stream to get one mono stream. notice that the power at 4 ohms bridged is exactly twice as much as 2 ohms stereo: by adding 2ohms for one channel and 2 ohms for another you get the 4 ohms resistance for the bridged channel. the power is also the result of adding up the values for each channel.
