Here's the story behind this. Take one (1) sealed box for two (2) 15 inch subs.
Rip off the face. Add an L shaped wall for a port, and put a new face on. Caulk
well and let dry overnight. Serves 1 to 8, depending on how many are in your
car.

When I realized I should be taking pics, It was too late to get ones of me ripping
the face off piece by piece. The Liquid Nails held so well that the MDF ripped
before the glue would. notice my amp is on the table behind it. I pulled that out,
too. I had been driving to silence for over a week, and to no bass for a few days
(plugged in rear fill) after I pulled the box.

Tools of the trade.

Here you can see the start of the port. It's 29 square inches a few inches over 2
feet long. Roughly 35 hertz according to most online calculators, not including
effective length. I didn't do any exact numbers, because if it doesn't work, I'm
just going to bug Jmac to give me my plans already. =)

Since both chambers were originally sealed, I saw no reason to change this.
Besides, I was told that 187s work equally well when sharing airspace or not.

The finished product. That gray stuff under the face is (get this) weather
stripping! Since this thing was such a b*tch to get off, I decided not to glue it.
This allows me to pull it off should I want to use it for 10s later on. All said and
done, it's only about 1.8 cubes per sub. You'll notice above the meow mix is
another enclosure. Sealed, 1 cube for a single ten. I used it with Lightning Audio
Bolt 10s. They were very very sucky.
I should mention that I didn't cut the port walls just right. There were about 1/8"
too wide. This puts a *lot* of tension on the box, but it's also going to kill most any flexing. I weighed the end product. About 70 pounds. That and my entry level incriminators will put nearly 100 pounds of bass into my trunk. It's very bulky, I hate having to lug it around.

So what do you think?

I'll tell you all how well the box works after I get the subs. Hoping tomorrow. UPS hates me with a passion. They had all the paperwork, but no subs, so I refused to sign for them. Blah.

There looked like there were a few miniscule air leaks around the weather stripping before I put the face on, but after smushing it with the pressure of and incredible number of screws (about 1 pound out of box) I think they are gone. Again, if all goes well, I'll find out tomorrow!

I have a feeling you will notice alot of airleaks after that box gets pressurized. Maybe get liberal with the silicon caulking and seal it up.
