Why yes, I can. Can you stop being a dick?
He never stated what head unit he had, or how high the volume was turned up. He never stated if he was using 0db sinewaves, or attentuated ones. He never stated if he used any eq or crossover that might have affected his results. He claims he set it properly, but why would he turn the gain up so the amplifier is producing 65 volts? If he set it properly it should be at 36.64 volts. He also never stated what multimeter he was using and if it measures rms voltage or peak voltage. There are a lot of question that were not asked or answered. So next time, why don't you think before you post a stupid question.
