Box too big for sundown SA-12?!

[lhs2011]

My box is 30x13.75x15 and used 5/8 baltic birch. So the whole box itself is 4941.4 cubic inches then i subtract the port wood used for the port which is 3.375x12.5x24 (port itself is 2.75 inches wide). When i subtract the two I then get 2.27 cubic feet. Is this too big for an sa-12?
If so is there anyway I can make the box smaller easily? thanks!

if i remember they like 1.75 cubes......u could always add some bracing to the box to help take some space away but i think u will be fine....just dont over power

did u build the box??

[The_Grimy_One]

Yea just *** mucho bracing. Plus I would recommend using 3/4" anyway so bracing will help.

did u build the box??

Yeah I did. Used liquid nails, nails, and then 3 screws for every side. And of coarse silliconed it up!

Alright cool I already Have 6 triangle wedges bracing but I def Will put more in now! Yeah I used 5/8 baltic so save some weight. Had 2 kicker cvrs in a 3/4 mdf box but it just weighed my civic si down way to much.
Thanks for helping!

Adding bracing to bring down volume is going to raise you're tuning. Play it how it is and see how you like it, then make changes if need be.

As RAM said, the tuning will change when you alter the air space. I would just play with it and see. It is a bit large for a SA sub, but it may very well do what you want it to do.

If I added onto the port internally how would you recommend doing that? Thanks
