I built a mono subwoofer (i.e. just one driver in it).
I assume that I can put the outputs of the two BeoCreate 60 Watts amplifiers in series (connect the '+' of the left channel output with '-' of the right channel output).
The loudspeaker driver will then be connected between '-' of the left and '+' of the right channel.
By this the two outputs are added to one mono channel with 120 Watt.
This should be allowed, as all the output pins of the amplifier are isolated to each other.
Or is there anything why this shouldn't be allowed?
