testing amp wattage

[Efreakingt]

Ohms aren't a constant reading, the resistance changes throughout the speakers range. You can model a speaker in a program like winisd and maybe get a halfway accurate estimation of its impedance at a certain frequency.

I agree with shadetree, the input signal is likely way to high if you're clipping that easily.

Here's a "4 ohm" 10" Dayton Audio ultimax in free air conditions.



Hopefully this helps you understand impedance.

if your getting 33.5v ac and using a 1ohm load that is about 1100w.
