If i parametricly EQ a rap song will it accurately sound the same in a sealed box setup?

A sealed subwoofer box has accurate sound. If i use a parametric EQ well done to have the right response curve and peak frequency, will it sound the same in the a vehicle? Like a SUV Envoy for example.

We know that a sealed box has a fall off at about 44 hertz or 43 hz that is smoothe like the size of a 2.4 sealed box with 2 subs. I'm talking more about 12 inch subs, say about 7 mm linear excursion peak I think it is.
