Knowing that situation I can heartily recommend:

https://www.parts-express.com/omnimic-v2-and-dats-v3-dayton-audio-speaker-m=
easurement-bundle--390-809

With that hardware and included/freeware software you'll be able to measure
and analyze pretty much anything speaker related in a home or auto
environment. I recently updated my test tool set to this and for the money
it's incredible. Like I said previously, back in the day it tool a $4000
Audio Precision analyzer to do what this can do for less than 1/10 the
cost.
