From there you can do in room or outdoor ground plane measurements. Depending on what you want to do, we can point you in the right direction to start.

I’d like to do in room measurement.

That isn't a perfect measurement, there are caveats there, but it is a start, and it can give you an idea of the response. Here is some background on the technique. Hopefully your sub isn't ported.
