Multi Amp Rigs

I was wondering if anyone knows how to hook up more than 1 one amp to play together. Is thier some method or devise that I can use? Im not talking 20 amps here, mostly 2-4 or 5. Well thanks for the help. -Sky

Ampegs have preamp-out/power-amp-in jacks on the back that allow you to 'daisy chain' as many amps as you can tolerate being in the same room with. I find that even one is more than enough.
