SA-12 Enclosure

[blindman4556]

im building a box for a single SA-12 for my 09 nissan altima.

i came up with this:

and the box

is there anything i should change. like is the port area good.

i might change the overall design a little to get the tuning a hair lower. just wanted to make sure its going to work without port noise.

and i will be rounding the port edges.

Could use a little bit more port maybe, but it seems okay!

[Neckbeard]

looks good! what program is that? the one that shows the box

How much power will you be running on that SA?

Are you looking for SQ or SPL? you might get some Port noise with it only being 2" wide... and 1.8 plus sub displacment i think its a little on the small side

If I were you I'd make the box bigger.

2.2-2.4 NET and around 12-14sq of port preferably tuned lower like 28hz is where I like the SA-12's

Your port extension should be 14" for an overall length of 30", no big deal though, you should specify power and type of music you listen to get more useful feedback.

yeah my bad . i listen to everything but mainly rap and rock. im going for SQ over SPL.

right now im just useing a kicker zx750. but i am getting a new amp. i havnt decided on what one yet, but looking some where between 700-900 @ 2ohms

so your saying i need to make the port wider, and box bigger? and tuned lower?

sorry this is my first ported box ive done. ive built sealed, but usually just paid someone else do my ported boxes.

Tune it low trust me you'll love 28hz tunage

I know next to nothing about SQ, but I believe people tune low low for SQ set ups. If you could go a little wider on the port you'd likely be safe from port noise.

ill have to take some more measurements of my trunk to see how much space i have to work with exactly and still have a semi functional trunk

im having a hard time in torres trying to make the port wider and box bigger and still get the tuneing down there
