[QUOTE="zane, post: 10407, member: 540617"] Typically RMS Power is 1/2 peak power. Lower ohm loads also force an amplifier to work harder- as the resistance is lower, which in a way- "fools" it into producing more power. Varrying Voltage will also effect the final power outputs of an amplifier. While RF may use 13.59V DC, a typical cars charging system operates at 14.4V DC while running and at about 12.36 Volts while off. No manufacturer uses the same tests to determine output power, therefore, thier in house measurements can varry depending on your cars charging system. Likely, at 2 ohm, the particular amp in question was measured at peak output. You should not concern yourself with peak output, this means little and IMO- should not even be measured as it misleads people. The Peak power is only the power of the amp at a brief musical burst, not all the time. The RMS rating is what the amp is guaranteed to produce all the time.- thus why it means more. take it easy, -zane [/QUOTE]
