Re: MY ? ?ACHIN ?ENDULKAR ? JUST LANDED BY THE JET ? Nah.... the amp gives you more RMS Power at 2 Ohm coz u need more power to get a better efficiencey with 2 ohm speakers. So even though RMS power @ 4 ohm is less, it will give better efficiency as the 4 Ohm speakers would need lesser Power to give you a better Efficience and Output Lol, this is getting technical.
