A friend and I were talking audio today and a question arose as to wether one could link ("bridge") a couple of amps or channels in either a stereo amp or multichannel amp togethor to effectively double the output to a speaker. ( perhaps similar to what is done when you switch an amp/reciever to bridge mode )

ie: say one has a 50 watt stereo amp. Could one connect the same input to both channels and then both outputs to the same speaker to get the equivalent of 100 watts output to a single speaker?

Would there be any problems with doing this, other than a bit of complicated wiring?

(Note: I'm not asking about using the separate channels to Bi-amp, but wether one could combine the channels)

Thanks for the help! Cheers, Jag
