thinkin about changin it up a lil bit... gonna build it when it stays nice out for a bit. i'm a little worried because i haven't seen something like this before... its 2.82 ft3 after all displacement and tuned to 25hz. i'm tuning it low because i can always cut the port down if i don't like it...

why do you want the exposed port?

 

[05F150SuperCrew 10+ year member]

i don't necessarily want it exposed, but i can't figure out how to get the port length and area i want and fit it all between the seats... that's why i'm throwin it on here... if u have an idea, it'd be greatly appreciated.

and that design encorperates a handy arm rest... and the first one would be above the level of the rear seat...

I would make kinda like a false space inside it to accomandate some cup holders and shit like that, looks fun

there should be just enough room in the front of it for me to pull out my factory cup holders and fit my mid woofers...

 

[jdawg 5,000+ posts]

I meant for the people in the back

 

[05F150SuperCrew 10+ year member]

they have cup holders on their car seats... i was thinkin about how i could work in the factory cup holders that used to be under the center seat... don't think its gonna happen though... i'd like to find another of the pass side rear seats and run the box all the way to the rear wall... but its not in the budget for this build.

I don't adivise a tune under 29 hz for every day driving.

 

[05F150SuperCrew 10+ year member]

cool... i thought i might be tuning it a lil low... but on the second design, its pretty easy to cut the port back. so i'm gonna test it out at 25 but just to see what it sounds like... it'll probably end up higher.

 

[05F150SuperCrew 10+ year member]

ok, just made a cut sheet for it... hopefully startin it really soon.

should be interesting... still not sure how i'm gonna finish it though... all i have to do is set up the table saw and get the mdf and glue. got the plexi already and finally got the last bit of wire needed.

edit.... btw, i'm takin your guys advice. this one is 3.18ft3 (after subs) tuned to 32Hz

that thing in the middle looks like flaps will be hanging into your port?
I would think thats a no-no?

unless im seeing it wrong.

what thing?

 

[05F150SuperCrew 10+ year member]

this help?

Yeah, I think I would go with the first design. The port will be less obstructed and also it will be harder for stuff to fall into the port accidentally. If you need the raised armrest area just build that separately, but I would keep the port on the bottom.
