Unknown Sub Power rating?

Hey guys,

So i was at an auction of sound gear today and i bought a lot of live PA stuff one of the items included in it is a sub. However it has no markings/brand names/info anywhere on the inside or outside.

I've figured out its an 8 ohm woofer using a multimeter however im not sure how to figure out how many watts it is which is kind of important if i want to get an amp for it.

any ideas on how i can figure that out? The woofer has no markings or anything on it help me figure it out haha

Thanks guys!

Chris

Hook up a very beefy amp, feed it a 70Hz sine wave, slowly turn up the level and when you hear it starting to distort, measure the voltage across the driver. From there, calculate the power it's handling.
