Well i was kinda late with the pictures but i guess never late then never.

I will be building a half wall with 1 15" Fi BTL. tuned to 50-51Hz, Sub forward and port forward. whoever has seen my car before they know that there always was a giant hole in the trunk to the cabin.


The box will be 5 Cubes with almost a 12inch port. this is just a trial box, might sound like shit, might sound good, dunno.



I will be making a changeable port to 33Hz, i have never had a box in my car tuned lower then 41 Hz. so I'm kinda excited on that part.

So i did some work yesterday....

Off comes the door

[Kian]

I will be replacing the front baffle with a double baffle. the rear of the box still needs to be sealed off. just hoping this box will be loud.

I think it's too much port area, a lot of port area is good but that is a bit too much i think.
Hope you don't launch cones.
Is it 5 cubes before or after displacement?
If it's after displacement, then it's probably a too big box for the 15 inch sub.

EDIT: if you're going to put 4000w thru that sub in that box, i'm almost positive that you will launch cones.

EDIT2:If my calculations are right you're going to have around 4cubes after port displacement with bracing and displacement from the 45's if you do them, you are going to have a really loud system.

I agree its a whole lot of port area. Its 5 Cubes before displacement. i made the box so i can easily trim it down in size.

Props on getting to a good start. I just can't see why you would sacrifice your entire back seat for a single 15"?

Good luck with the rest of the build

If it does not put me in the 49's+ im going to be pissed.

good luck with this build, street max is a VERY HARD class.

lots of port is good but probably too much airspace for that 1 15.
what battery are u goin with?

Im probably going to drop it to 3.5 Cubes. I will be going with 1 D3100

Yea im going to do all 45's in the entire box, then use 1/2 inch thread rod for bracing. if it works well i'll resin the entire box also.

[treossi]

it looks bad ass man, i'd like to see more pics so get on it....

[matt402]

fyi, brace the box and test before u add 45s. (they dont always give gains)

good battery choice .

Yea the D3100 will put me at 756.81 in^3 the battery limit is 800 in^3.Then i am going to need to find a good 2/0 AWG power/ground wire for my amp.

Good luck man

[Kian]

Did some more work today.

Some 45's



Some bracing

[Kian]

Did the right and the left triangles

all the openings will be sealed off with Liquid nails.

The box has to be pushed back a lil.



Started to use the expanding foam.

Monday or Tuesday i am going to do a complete redo of the baffle.. Anyone know what the exact cutout radius is for a 15" woffer cause i completely F'ed up the current hole.
