So 2400 watts at half ohm is the same as 2400 watts at 2 ohms. The reason electrical setups need to be so much beefier on .5 ohm loads is bc the amps efficiency drops making it have to draw more current to produce the same power. Amp A draws 100 amps of current at 14 volts and produces 1200 watts at 2 ohms. Amp B draws 100 amps of current at 14 volts and produces 1200 watts at .5 ohm. This would only happen if the efficiency of both amps were equal with respect to impedance. Real world would have amp B having a 130+ current draw to overcome the inefficiency at a half ohm load</p></blockquote><p></p>
