I have never done this. A stereo amp can be converted into a mono strapped amplifier by driving both channels with the same signal. However, the signal to one channel must be inverted, i.e. multiplied by -1, with an op amp inverter. Strapping an amplifier doubles the available drive voltage to the loudspeaker, thus quadrupling the available power. However, each channel of the strapped amplifier sees one-half the loudspeaker impedance. I know of no reason why either amplifier can’t be strapped, but I have never tried it. I would not recommend strapping any amplifier to drive low impedance loudspeakers.
