This is the design I have come up with.

It will fit in my trunk perfectly, and just within an inch of everything. It will be made for this car. lol

The speaker will fire in to a sort of cavern area there directly behind the speaker, and then it will find its way down and around the bottom. Where it starts its port journey to the outside world. The box will be divided in the middle to essentially produce two boxes, with around 1 cu.ft. each of volume. Guesstimation puts my vent length at between 25-30". And with a desired tuning Fq of 37.7 Hz, a 2x9" port will be perfect for a 27" vent.

Should I be rounding out my vents? or will it be OK to run it how i have it drawn? Also do you like that the ports are on the top? they will fire sound in to the cabin that way right up through the rear deck that is just thin fiber board with holes all over and a thin carper on it. Or what i was thinking maybe, is to continue the vents and put the ports above the speakers on the speaker face, firing in to the trunk.. What do you figure?

I figure this:

1: Build the box for the subs, not the car......if the air volumes are correct for that sub, with a couple of exceptions you can build the box any shape you like.

2: It looks more complicated than it needs to be. If your taste runs to having the ports above the woofers that's fine, but don't guesstimate your port.....a badly tuned ported enclosure will sound like poo and you would be better off just running them sealed.

3: More info on the vehicle and the sub model #s would help us help you.....

BRG, Thanks for your input

Yes The box is being built to the subs, each of which require 1 cu.ft of space in a ported enclosure. But it will also fit snugly between my shock towers :P

The last box I built was a sixth order band pass, and it made a shitty Visonik sub come ALIVE! it came in a sealed box rated for like 50w rms with 150peak. SO I built it a sixth order box tuned the ports to its proper frequency, and gave it a lot more power.. holy crap does it pound. sounds better then it really is

I wasn't guessing on the port, I just don't have any solid plans down yet. So in the big picture the vents need to be 27" with a 2x9" port.

The car it is going in a 1981 Vw Jetta, massive trunk so this box will only take up less then half which is perfect. The subs are Sony Xplod's XS-L104P5B. I am looking for an amp.. A fair price, good name 1ch that will be able to give me around 700-800w RMS @ 2ohms, and is 1ohm capable. Is there any models out there that you know of that would suit my needs?

thanks a lot guys.
