how does this look?
I was on another forum and this guy was giving free box dimensions so i thought I'd pm him and see what he would come up with for my 13Ov.2's.
Here's what he said...
Good Morning, well these subs need a bit less chamber space so the enclosure will be a bit thin, based on .35^3ft sub & bracing displacement, and .75" thick MDF, build it 14"H x 49"W x 14.25"D, this will give you 4.381^3ft gross vol. Build your port, 12.5" x 3" x 20.1"long@35Hz. This will put you at 3.565^3ft net yield. This design will do the job very well.
How does that look? does it sound right for what the 13Ov.2's need? or should I pay no attention to it?
comments....

Looks like a well thought out box. Personally I might tune a little higher but the most important factor, size is there.
I would go with that design as is.

should i put the port in the middle instead? subs and port are firing to the rear. I was thinking about just putting the port in the middle but what kind of changes would i have to make in order to do that?

I know that you are aware that i'm really in the dark about these things. so if i want the vent in the center of the box i would do it 12.5" x 3" then have two 10.5" boards for the port2 measurements? is that right?

Looks almost dead on, he must have used bassbox. Do you have 49 inches across in your trunk? seems too big to me. I can make a smaller box if you need it.
