WARNING: NEVER USE A LOWER IMPEDANCE SPEAKER THAN THE AMPS IMPEDANCE RATING, AS THAT WILL CAUSE SEVERE DAMAGE TO THE AMP.

I studied amplifier design in the seccond and third years of my degree, this does not agree what i've been taught.
If the power is not being fed to the speaker then it is being dissapated inside your amp, therefore an impedance missmatch, be it too high or too low, is bad.
