Just got back from the JL Audio design center. They took measurements of the truck and brought out a few speakers to see about fit. They determined that the best fit would be the new Shallow depth speakers their about to release. They had a few blank cages of the speakers and they look like they will fit pretty well. They where thinking either two 10's or 12's but they will decide in the fab process. They will be calling me again in three weeks to begin the internal fab on the truck. They mentioned that the shallow speakers would most likely be ready by January due to the fact that their show
car has them installed and will be at CES in January. I'll keep you all informed going forward.
