Has anyone made a sub box that is also a partition for the FRC/Z06s? I really like the decrease in road noise with the partition and thought is would be great to incorporate an enclosure (I'm throwing out the option of an enclosure in the rear center compartment b/c most of the sound would now be blocked). The partition could be the front of the box holding the sub(s) and extend the box toward the rear. Which and how many subs (1or2) could be used? Which ones also work with minimal volume? I am not looking for bone rattling bass or something comparable to the stealthbox, just wanting to add a considerable bottom end without taking up too much space if it is feasable.
