I can't say exactly what size box you should do because I'm not so sure what you want. Do you want ported or sealed? Also, I hope the 4 liters of box volume is a typo because that isn't going to happen. Ground Zero recommends 40-70 liters for a sealed box and 80 liters for a ported box.

sorry thats 4 cu ft and ported for around 35 hz thanks

Use all the space you can afford to give up. Port and sub facing the same way, pointing back if there is some decent amount of room around the enclosure for the wave to pass by. If not, face it forward and seal it off from the trunk.
GZ says 2.1cuft net for the sub but that seems awfully low. If you have 4cuft to use, after all displacements you'll probably end up with about 2.7cuft net using 17sqin/cuft port area tuning to 32hz.
