i have been killin myself trying to figure out a box design for my ranger and have gotten nowhere with it. i got a couple reply's on other forums but nothing set in stone. the sub is a 15"btl and my dem are 50" wide x 16 tall x 16 deep, 5.9cf before sub displacement and port displacement. i need it to have ports on both sides of the sub cause i want the sub in the center of the box (its that way to even out the weight in the truck). i would like it tuned to around 33-34hz.. any help on figuring my port length would be great. please put in laymans terms cause i am not very bright when it comes to this kinda stuff. any help would be greatly appreciated, thanks btw the sub and ports are firing to the roof here is kinda what im talking about.

this would be the top view except more even and exact spacing between the rods. (i guess i just wanted to play with paint.lol)

somthing like this, there would be four rods evenly spaced with a nuts and washers on the inside and the outside of the top baffle to minimize the box flex

how do u think i should brace it? if my numbers are right i will only have 16" between the ports at the bottom of the box. i was thinking of going with threaded rod and just go through the bottom port but i wasnt sure how that would affect the sound.

it will be made out of 1" mdf. are these numbers right? how should i brace it?

can you draw me up a diagram?

sorry bout the confusion. so should i just go with the port size 14" down into the box then "L" it over 16" to keep the 2" port size? how do you think i should brace it? i have never had to built a box this complex before and i am trying to do this box the right way because the sub tore apart the last box i made for it. thanks for the help

i cant go with any longer or shorter dimensions, it will be placed on a false floor and it would look tacky if the box was shorter than the floor. i want to stay under the back window line for the height and i dont want to lose anymore leg room/ seat recline for the depth (17" is already pushin it) thanks for the help though. outer dem. 50 long x 17 deep x 16 tall. sub and ports on the top of the box.

it will be power buy 1100 watts off a memphis mc1000d for now. as for the music i listen to everything but mainly rap or bass songs while im driving with the volume up.

anyone?

my dimensions were wrong, the correct dimensions are 50 long x 17 deep x 16 tall. thanks, josh

i am looking to try out a new design in my ranger. this will be for a 15" btl fully loaded. my max outer dimensions are 50 long x 16 deep x 18t all. heres the kicker, i would like the sub in the middle of the box facing the roof and would like to have the ports doing the same on each side of the sub. i am looking to get it tuned to 30-35 hz. the only reason i want the sub in the middle is because my truck is bagged and i want the weight in the center for even psi on both sides. i live near milwaukee wi if anyone is wondering
