Assuming there's bass output at those frequencies.Bass notes sound like bass notes to our ears whether the room is large enough for a full wavelength, or not.
Much bass heard in a car with windows closed is transferred via full cabin pressurization because the car interior is usually too small for wavelengths of frequencies under about 50 to 60Hz (higher in a small sports car).
Bass is MORE accurate below the modal region simply because there are no room modes to ruin the frequency response = 'room accuracy' improves. Your statement "When the frequencies are lower than what can accurately be reproduced" is simply not correct.
The only potential problem below the modal region is in cars where the subwoofer has to be designed to account for the potential of up to 12dB/octave cabin gain. Cabin gain started at 50Hz. in the last (mid-sized) car I designed a subwoofer for. Deep bass can be much too loud if cabin gain in a car with windows closed is ignored.
