I don't think you can, you just need to measure it while the box is in compared to when the driver is not in the box

You can measure it.

when you have the woofer in burp at a given freq. and with a DMM and Amp clamp you can calculate your wattage and also to which ohm load you are rising to //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

oh ok. hmm ya. well then what you posted would be the right way. the woofer sitting in the box it wont really matter. its the length and gauge of the wire used from the woofer to the amp. If you have a small gauge and long length of wire. your rise will generally be higher than bigger gauge wire and shorter length
