With regards to putting your seperate amp speakers in phase. Please use the speaker wire switching method.
If your amp's electrical cord does not have a three prong outlet, have one installed immediately.
Inverting non-grounded plugs between amps may leave you with a live chassis & a grounded chassis. Simultanious contact with thes amps may leave you with more than a tingeling sensation. I don't know what happens when a guitar cord is connected between such amps, but sparks may fly!
