That would depend on the particular amp, wouldn't it? It is possible to design an amp with adequate cooling when it is mounted in any position. One way to do it is to add a fan. Another way is to design the amp so that convection cooling works equally well in both directions. Most amps have the heat producing components mounted in the sides (as opposed to the top or the bottom), probably for this very reason.
