Hey I have an OBS GMC and was wondering if anyone has been able to build a box for 2 12's underneath the back seat. If you have please post pics and info on size. Thnx

You should have no problems fittin 2 12s under an OBS truck. The box im buildin for my friends dakota would be able to fit 2 12s, but we are just stickin with 10s. someone might have some measurements, but you can always go out and buy a sheet of MDF and start cuttin and guessin some...and if you cut enough times it will actually turn out alright...if you take your time, you should have no problem. ohh yeah, silicon in the corners is your friend.

Ya but i was really hoping for some dimensions. I have looked on cardomain and got in touch with this guy that sent me dimensions for 2 10's with .88cuft each. But I was really wanting dimensions for 2 12's

do you mean the actual dimensions of the speaker box or just the volume of the boxes...
If it is just the volume it will give the range on the specs for the subs (if you can find them) the hard part is calculating the volume of your box...even though really that is not too hard either...

yeah, calculating the actual box volume isn't hard with just MDF...its next to impossible to be exactally accurate with fiberglass...theres even a calculator out there for finding the airspace of a box, even factors in the thickness of the wood and everything...also, depending on how the box it built, do u see any way to slightly modify it to get 2" extra out of it for the sub? like is there atleast an inch of material on each side that you could cut out for the 12s...BTW, why can't you stick with 10s?? sure theres not as much area, but unless you are gonna compete in sound comps or something, 2 10s will be plenty enough bass if you build the right enclousure and have the right amp powering them and everything...
