What length would I need if I used 4? I have the box pointing up and I dont want the ports to fire into the side of my jeep's cargo area. The front height is 14.75" outside, so 12.5 inside dimension.

Inside dimensions of box are 34.5 x 18.5 x 12.5

firing to the side would be fine, or just point the sub towards your liftgate and have the ports on that same side.

Your gonna need to use PVC and get 90 degree turns to put port on the sub face side cause the ports are to long.Not a biggie.

25HZ= Two ports 4" PVC need to be 25.5" long.

Youll lose output but you like the lows you try this first.

How hard would it be to make a slot port with the front baffles out? It's still removable...

not incredibly hard...but it wouldnt be easy, just do some measurements and drill some holes

Cuts look pretty straight for using a circular saw.

x2, nice job. Did you make the cutouts with a jigsaw or a router?

I thought it was generally said that you tune a ported box low (20's) to get the response that a sealed box would have...

...If he wants lows, he should just stick with an oversized sealed.

Jigsaw. The holes were absolutely horrible. I'm going to order a Jigsaw Compass so I can make perfect cuts.

i LOVE screws. They make me feel secure about the structural integrity of the box. Plus since I did it right, they are very nice. Pre drilled, countersinked, and torqued to maximum before stripping (I love torque settings on my drill, makes it so much easier)

I know you won't believe me, but putting more screws in there actually LOWERS the structural integrity of the enclosure. Even pre-drilled holes reduce it. Will the enclosure fail? No; I doubt it. Is it weaker than maybe 1 or two screws per side? Yes.
