If used in a 1.2 cubic foot sealed box your F3 will be about 35Hz. If used with a plate amplifier with 25Hz boost, your F3 will be about 24Hz. An in car response with 6dB of cabin gain should get you below 20Hz.

If used in 1.2 cubic feet with the SW26DBAC-00 passive radiator you are 3dB down at 27Hz and 6dB down at 20Hz.  That is without any boosting.
