I think that's a fallacy. You're talking about power supplies->amplifiers, I'm talking about power->power supplies. The power supplies should be able to handle stuff that's around the right voltage and amperage just fine. If the power supply does not supply adequate power or the amplifiers don't amplify it enough or adequately, then the given amp can't handle 4 ohm speakers.
