3 Ohms is more powerful than 8 Ohms. This is because Ohm is the measure of resistance in a circuit to the flow of an electric current. This means 8 Ohms is more difficult for current to flow through a given circuit.

If the loads are wired in series, add the three values to get the total R. If they are in parallel then the formula is 1/R = 1/R1 + 1/R2 + 1/R3. The total resistane when resistors
Ohm is the measure of resistance in a circuit to the flow of an electric current. The greater the ohm value the more difficult it is for current to flow through a given circuit. As speaker impedance decreases, more current flows and the amplifier is called upon to output more power to the speaker.
