I was wondering if there is a pre-made sub box that goes between the rear strut tower brace and the seat backs kinda like the JL one that will fit 2 FI Q 10s? or might I have to get a shop to fab one up for me?

 

This would be your best bet....it'll give you .70 cu ft per sub in seperate chambers:

should I just PM you whenever I have a question about anything SQ?

 

After looking at that box, I looked at some of the specs and the box says .70 cu ft per sub/chamber, and the Subs say they require a sealed box: .2-.6 cuft. What can be done to make this work?

 

with sealed enclosures, you have about a 10% margin of error. You will probably never hear the 0.1 cubic foot volume difference.

However if you are really concerned about it and it will cause you to lose sleep at night you can very simply use a block of wood cut to the dimension of the space you want to subtract and glue it (liquid nails) inside the box to take up that space.

So the volume of the chamber = .7 cf
The sub wants a max of .6 cf

you need to 'remove' or take up .1 cf of space.
use a 2x4 (for simplicity we will say a 2x4 is exactly 2"x4" even though it's not). 1 foot of 2x4 is 2x4x12=96 cu inches, you want to achieve 172.8 cu inches (1728 ci per cf divided by 10), so 172.8/96=1.8 feet of 2x4.

Do the actual math using real world dimensions of a 2x4 to get the exact length needed for .1 cf.

 

Don't forget that the sub will take up space too.

 

+1, not sure on the Fi Q, but your average 10" will have a displacement of about .05 cf, about half of what you need to remove from the box, so your 2x4 scenario above would be cut in half........or 0.9 foot of 2x4.

 

an FI Q10 is actually pretty huge, according to the FI website it displaces 0.12 cubic feet so you're good go to with no modifications.

 

WOW, well there you go!!!

 

Have you looked at the boxes available from Wicked C.A.S.? I have their corner box w/ a 10" JLW3v3 and love it.

 

hey thanks everyone.....sorry I took so long to respond....at my last stop before I come home from Iraq. I looked at the wicked CAS boxes, and none of them looked like they would work with the sub I want.....thanks

 

After making many boxes for people I would recommend having someone make it for you. Pre-fab boxes are pretty good but a custom box is most of the time better, because it is specifically made for your speaker. That way they can also make it to fit the way you want it to fit.
