Change a 2 channel amp to a mono block amp


Is it possible or wise, to take a 2 channel amp and by crossing or jumping the binding post. Make it a Mono block amp with more power? If you had 2 identical 2 channel amps rated at 200watts per channel, Could you make them 400 watts by combining the channels in them? What all would be involved?
Thanks Pete

Unless the stereo amp is configured internally for mono operation, you can NOT bridge it. Don't even try, flash...puff...smoke and maybe a tripped circuit breaker.

20 or 30 years ago, there was a company that made a little box that supposedly would bridge a stereo amp, but it didn't work very well.

If you do a search on here, this has been discussed several times before.
Do the speakers have bi-wire option? If they do you can bi-amp them! Otherwise like Mofi said,forget it!
It might be possible (if each output isn't already in bridge configuration) by shorting grounds together and connecting speaker between outputs. Input to one of the amp has to be inverted. This will get you 800W but as Mofimadness suggested it is not wise to do, since amp was not designed for that (power supply, heatsink, output transistors etc).
