For shipping a heavy amp, I'd look to see if I could find a properly sized Pelican or SKB
hard
case with handles and "luggage wheels" and no foam. Encase your amp with an inch or more of rigid foam board, fit it nice and tight. Hard polypropylene case, tight fit.
Making your package easier to handle with sturdy handles and wheels go a long way toward getting your amp to it's destination safely. I've shipped 90-100 lb amps any number of times in country and Canada & have never had an issue
