Looks good.

Are you on F150online?

[coobies5 43]

yeah, i never get on there though, im always on here or texastruckscene or performancetrucks

[5.4SPL 0]

Ohh alright. I spend a lot more time on here and RoE, especially when I'm putting most of my income into stereo equip. at the moment, haha.

[coobies5 43]

gotcha.

anyone else have any suggestions or guidelines?

sub up ports to the side... much louder at the head rest (MECA Style)

any good box designing programs i could use to figure out the specs for it? or possibly can you help?

yeah I'll get you some rough dimensions... it'll take a couple

[coobies5 43]

thank you thank you

48 x 20 x 18

gives you roughly 6 cubes after all displacements (pending on how heavy you brace, dimensions only good for a single layer of .75 inch material)

w h L

17x5x27 slot port gives you roughly 30 hz (port consumes 1.66cubes) (I allowed .5 cubes for woofer and bracing)

fire sub up on pass side and port towards drivers, flip box around to be louder on the other side

Id suggest that you atleast double up the baffle

fire sub up on pass side and port towards drivers, flip box around to be louder on the other side

loud side=port side

Usually if you roll down the window on the sub side you gain a ton of output on the portside headrest... open the door and it gets even louder... I use that design to show off at car shows. I let the people get in and shut the door then I just leave mine open...

*all shut up my pass headrest meters about 1db higher than the drivers (my ports are aimed at pass side)

possibly tune it to around 33-35hz

how much shorter would i need to go to do that?

[rushnrun 14]

about 15inches long

you could increase port height to 6 and change the length to 22 for more port area and a 34hz tuning

[coobies5 43]

alright, 1 sheet of mdf should do the trick?

[coobies5 43]

still up for other suggestions, sometime next week i'll choose a design.

[rushnrun 14]

1 SHEET won't do it... I think the best you could end up is a sheet and a half. one sheet will cover the top, bottom, front back and sides the other sheet will be needed for the second baffle layer, port, and any bracing....

the sheet will be 49x96x.75 you'll need:

2 20x48

2 16.5x28

2 16.5x18.5

1 16.5x(port length)

2 (port length x port height)

[coobies5 43]

alright, thanks again.

had a mistake on the other.... wrong port width... these are right.

[coobies5 43]

thanks for looking out, i appreciate it.

[coobies5 43]

side firing port wins, bout to start measuring and cutting tomorrow if work and weather permits.

[rushnrun 14]

well have fun building

I assume you undersand how the port goes together..

these dimension make the box a little easier to build (you don't have to cut out the opening for the port this way)

If you don't understand how it goes together I can make a quick sketch.

2 20x48

2 16.5x28

1 16.5x18.5

1 (16.5 minus port heigth) x 18.5

1 18.5x(port length)

2 (port length+.75") x (port height)

make sure you post pics

i kind of have a idea, but i wouldnt mind a image just so i do it right.

[rushnrun 14]

I'll be building a box tomarrow with the same basic design.. If you want I can post some assembly pics..

[coobies5 43]

doesnt matter to me, probably wont be able to start working on it, till a few days, damn hurricane. sub is supposed to get here next tuesday, and about that time, the hurricane should hopefully be done for so then i can go out and start cutting, if i dont today.

[rushnrun 14]

I'll get a pic posted in a sec... takes forever to upload on work's dial-up

[coobies5 43]

dang, didnt even know dial up was still in use...

[rushnrun 14]

yep,, it moves at a blistering 14.5k/sec

doesn't matter, I've got all day.... well until 4

[coobies5 43]

haha, im bout to have to go grab some supplies and what not for this hurricane.
