I am using a subwoofer box calculator online and cant find the QTC of an IDMAX 12 D2 V.3. does anyone know what it is? and what is "F3" of a box? and how do you find that?

Do you meen f^3? The "F" stands for feet, so it's saying feet squared, or the volume of the box.

No, never mind. If it is exactly F3, then it's the -3 dB cutoff frequency.
