1.5 cubic ft of internal airspace tuned to 32hz. 2.25" wide port with a tad over 23 sq. inches of port area! Externally, it's 29.75" wide, 11.75" high and 14.5" deep. That's sub and port facing back.
i believe sub up port back is the preferred arrangement for the Grand Cherokee and id move the port area up to at least 32 square inches if your putting 1500 watts on it or plan to in the future but that will make for a very long port
I would if i had the money, I went all out to get the sundown 1500d to give this thing all the power it requires and i moved my 250.2 to highs (thing sounds crazy loud now)
Sean what all would changing the port area from 23 to 32 sq inches do? Im still learning this box stuff.
well not having enough port area will cause port noise and possibly lower your output....also if its bad enough you could damage your subwoofer but in your case that wont happen....I think if you make your port of 23 square inches with a flare at the exit of the slot port you might be ok....its just that using linearteam I like to keep the vent mach lower because I made a box with two 4 inch pvc ports and on 1500 watts I had port noise when I cranked it on certain songs and the vent mach was .11 and yours would be .14
