Gunz That Turn on Nunz
you never ever see 1 ohm unnless you have a resistive load on a test bench like the Amplifier dyno. The RMS rating of the subwoofer is on an actual 500 watts after impedance rise Like for example the sundown woofer rated for 500 watts thats 500 watts after impedance rise a true clamped 500 watts for hours on end without failure. Most normal people dont understand rise because you guys never competed in power restricted classes where they clamp test for true real world power to make sure you are in your class. You are NEVER getting the power you think you are getting. Its always WAAAAAAAAy less.Understood, but in the above example, what happens at 1 ohm resistance when the amplifier is dumping 1000 watts of energy into a voice coil rated at 500 watts root mean square? Curious.
Am I misunderstanding something? Kindly advise.
You dont look at peak dynamic power, only RMS and certified numbers on the amp dyno. That audiofrog would be slightly underpowered because the lowest impedance you'll see is around 8 ohms and higher on music at best you'll see 300ish actual real world power if you arent soft clipping it.So would it be acceptable to run 825 watts at 4 ohms ( Zapco Reference 1100M) to a 500 watt rms (Audiofrog GB12 4 ohm subwoofer) The peak dynamic power of the Zapco 1100.1 is 1625 watts, not sure of the Audiofrog GB12.
You also need to look at it this way. An amp operating at 80% capacity vs one being redlined at 100 to 110% which amp will run cooler, more efficient vehicle voltage wise with cleaner power, lower distortion and longer life span?
