Box specs:

Rear chamber:

6.0 cubes net

(2) 3.5" octaports tuned to 26hz

Front chamber:

6.0 cubes net

16" octaport tuned to 58hz

Pictures as they are taken...

Port internal or external firing into the cab ??

I know anything you build looks spectacular. All I'm wondering (having a blow though in a 90's chevy) is how much do you think the owner is willing to cut out of his cab to make that LARGE port fit ???

EDIT: Cant type for some reason. LOL

External port. He said he had 18.5" tall to cut, so we good on room. :D This is a lot better than the "typical blow through" thats built by local shops or "pros"... Just a ported box in the bed and cutting just about every square inch of the back of the cab out.

Designed a box for a guy about a year ago and had a friend build it. Guy was originally running 4 HDC3 15's in a "blow through" (ported box and a massive hole). Designed a 6th order for 2 of the 15's. Went from a 143 to a 149, with 2 less subs...

Gothca.

Yea, I like the idea of cutting just enough for the port also. Just not so sure I'd cut 18.5" out of mine.

I think my max height cut was 12" (give or take an inch, but close).

Carry on brother !!!

I don't think hell be able to cut 18.5" out of an obs cab. I cut 15.5" out for a blow through and that was kinda suspect. That low in the cab and the metal is corrugated and the accordion boot doesn't seal well, below the window is a boxed out section to cut- I replaced it with a length of 2x4 square tubing

Well the port is only 17" tall, so it shouldnt be a problem..

No reason to brace the rear ports. They are VERY solid.

Ive been building furniture and boxes for almost 10 years now. However, ive built roughly 90% of my boxes (around 150) in the last 2 years.
