Testing amplifier wattage

[Oraclem19]

Anyone here used a resistor pack to test the ideal wattage/wattage of amps at rated numbers?

Looking into doing this to ensure no overloading subs, maximizing rms to systems, ensuring amps operation etc. but not sure how many watts I need the resistors to be rated for.

Anything over 100w of resistor is hard to find, but due to the small amount of necessary test time to set gain, would it be possible to use a few hundred watts of resistors to set gain into 2-3k watts? So long as the test time was short and the resistors were kept cooled.

I have 200 watts of dummy load screwed to a steel plate for heatsink:

For short tests (a few seconds) I can immerse them in a bucket of ice water and they'll be OK to about 400 watts. But if you run them at more than 2X the rating they'll burn out quick. You can get power resistors from Mouser or DigiKey.

Hmm I wish I knew more about this, im interested in testing all of my amps outputs as well.
