Max Depth 28

Max Width 32 (safely 30)

Max Height 14

Desired Tuning is 34 HZ

Only option is to upfire

Here Are Some Specs

Ported Minimum Box Volume 5.5 cu. ft. Maximum - 8.0 cu. ft.

Mounting Depth - 9.6"

Woofer Displacement - 0.22 cu. ft.

Can someone please pm me an ideal port design for this box (34hz 32 Would be great)

port has to be wood no aero :(

the brand and model of woofer would greatly help..

i put these dimensions in - 14x32x28 - that you gave, no other numbers input and your net space is only 5.85 cubes, gonna tell you right now, you will not get that 18 in your trunk in a proper box, no way in hell especially if your looking for any lows

cut it up and recone it as a 15 is my suggestion

4.38 after all displacments with a tuning of 33hz was the best i got, thats including stupid small port area, gonna be too small for any 18

I think you would be better off with 2 12's instead of 1 18'(in case you haven't bought it yet) in my opinion since your trunk is small.

This is actually pretty easy. 1) put 18" woofer in trunk. 2) admire woofer in trunk. 3) tell buddies you has 18" woofer in trunk.

Or find a sub that will fit in those specs. 2 12s would be easy and comparable cone area iirc.

If you really want to do this I would suggest building down into the spare tire well. I was able to get 1-18" front firing sub into my 94 honda accord trunk by using the spare tire well for air space and I used it to gain the height on the baffle wall to even fit the 18" in there. You will have to build a custom fiberglass tub and glass that to the box but it works, it hits the lows, and its loud. Plus it won't rattle like it will when you fire that thing up.

It would do a 149@35 hz on the dash windows open. I will warn you this is not for the 1st time installer though, it is a pain in the ass to build like this in the trunk. ;)
