Hey there I trying to design a box to go in the back of a 96 ford ranger extended cab. I'm wanting it to sit on the little 6" curb to utilize the floor space for cargo and passengers legs. I also want to be able to use the rear fold down jumper seats which leaves me with about 16" in between them in the center. The highest I want to go is 21" which is at the lower edge of the rear slider window. The sub I'm using is the JBL GTO804. I want it to have the .6 cf (it's what's recommended). With a slot port tuned to 33 hz. I want the speaker front firing and the slot on top pointing up. I have come up with some box dimensions but I want to be sure I'm on the right track. Anyone have any suggestions or criticism??

No subsonic filter on this amp. Old punch 150a2
I think I see what you saying though. So in other words to avoid port noise I need to stay around the target number 10sf. But to tune it that low I would then have to add about .28 cf to get back to .6 cf

Not sure if this helps but one old school trick for these situations when any extra space is a blessing is to actually build the box onto the back of your cab. The rippled metal behind the seats is the back of your sub box. Basically you place a panel up against the metal then use a compass to trace the ripples, then cut it out with a jigsaw. Use those for your top and bottom. Basically just build a box with no back with these rippled panels, then screw the whole thing on. Put DynaMat on the metal, possibly screw a brace or two on, seal it up with silicone. I've built one of these in a Ford Ranger before.
