[QUOTE="Buck, post: 8723457, member: 591582"] If you can OP, see what your group delay is if you do 6 cubes with the mojos and how xmax looks away from tuning frequency. I don't get why they recommend 3.25 cubes per 12. That has to be gross and not net. If I was you, I'd sell them and do 2 15's like maybe Dc's or sundowns or 15's that'll fit in 3 cubes net. If you do the 12's, I think I would try to aim more towards 5 cubes net, or I would. Further looking at t/s of the 12" mojo6, they look maybe like relatively weak motored. They don't post the Re. Xmax is low too, that may be why they want it in a larger ported box is to try to make it a little more efficient. I wonder what the Xmech is on these. They don't give the Re configuration so their Bl doesn't mean much. Ugh i'm not opening a design program though. You can and look at the Re and Bl ratio. Still seems low to me. You might benefit greatly from a quasi-series 6th order with these. Do a small port area and have some sort of front chamber with some sort of loading wall. Idk if that would even begin to fit in your space. You could do a center port exiting rear and have the subs facing each other inside of the port, right at the exit into the vehicle cab airspace. That'll help with the lower xmax, keep the cones linear. Hey [USER=674047]@shredder2[/USER], with 2.1 cubes sealed, what's his Fc/Frc on that? [/QUOTE]
