resonant frequency on a explorer thanks if you can help

my explorer isnt very sensitive to tuning frequency. at 36hz it was -.1 from 46hz. box volume and box design are the things you want to work on.

I think our 2 door Explorer is peaking around 45 hz and the 4 door peaks in the low 50's. The 2 door needs a lot of work, however. Our note may be off.
