Whipped up this design for a buddy and his Tahoe. The American bass drivers are not the smoothest but with a bit of finessing it I got a nice response curve for them. It took a little smaller enclosure than I would have liked but he has gobs of power and I went on the high side with port area and will roundover the ports so there shouldn't be any noise or chuffing.
