It is obviously wired incorrectly now, or something is seriously wrong. 
  Without knowing the type of amplifier (make/model, homebrew) it's 
impossible to give you advice about what to do.  Even then, your problem 
could be tricky.

I don't want to come off as a wiseass, but my impression from the way 
you phrased your question is that you should get someone experienced to 
help you.  Amplifiers can be quite dangerous, as you probably know.
