They should be just as sturdy as any other amp in a rolling road case. I mean if you are rolling it on a smooth surface like pavemet. There are no worries. Even on rougher surfaces like cobble stone it should be fine, as long as you are careful, try not to be to rough on them, and all will be fine. Just don't throw them off a cliff or anything, you should be ok. Even worse, please try to avoid throwing them off a cliff into a body of water. They may still work, but I wouldn't take the chance, because that would probably void the warranty
