I'm looking at building a custom box for my 2 fully loaded fi btl 15s and need some help with the dimensioning. Im looking at have a 9.5 net cubic foot box tuned to 32-34hz with a solid wall brace in the middle separating the two subs. For power im looking at either 2 rf t2500-1bds, 2 sundown audio saz 3000ds, or a autotek mean machine 4000.1. Does this seem like a good setup. Im looking at putting it into a chevy silverado ext. cab of course with all of the electrical upgrades also. Thanks for any help

Your first step is to get the max dimensions of the area you have dedicated to an enclosure and somebody on here will be able to assist you. (height x width x depth)

Also what will your electrical consist of?

Max Dimensions are height 27" depth 22" and width 60"

That is a lot of air space. . .

Could easily cut the width and height down. What is this going in?

Yea i know i can cut it down i was just giving the max dimensions. Its going in a Silverado ext. cab.

I guess I was asking which dimensions you wanted to cut down. . .

I now see you already posted the vehicle type. . .my bad.

Subs and port up, or facing forward?

PM me an email address and I will send a design to you.

I would rather have the depth cut down a little the rest dont matter, im lookin at sub and port both up but i still want it to be 9.5 (4.25 each chamber) NET cubic foot after all displacements. Thanks

9.5 total, or 4.25 each? 4.25*2=8.5

How about this. . .

9 ft^3, 120 sqin of port tuned 33 Hz.

box is .75" material except the top which is 1.5" thick.
