Fierosound, thank you for the clarification. I ended up completely rebuilding the subwoofer box to make it MUCH bigger and getting it all sealed with fiberglass. I'm using a sealed volume, so the tube cut didn't matter.
BoostDreamer,
When I added the wood across the bottom, I used "L" brackets to attach a larger piece of wood to the bottom of the box. That way you don't have to worry about splitting the wood. Seal the seam with silicon.
Also, you need to make sure the + terminal on the speaker is connected to the + terminal on the amp. Polarity Does matter in the way the speakers sound.[This message has been edited by PaulJK (edited 05-05-2014).]

By the way, I have a neobium TB subwoofer speaker in the Mall for sale if anyone wants to do this mod. I'll probably be listing another one (not sure if it's neobium or not) already mounted in the speaker box soon (it will b plug-n-play).

I guess I got lucky. I only made ONE insert for the speaker from MDF.
I predrilled the mounting holes and used the original subwoofer housing screws.
Wood screws are basically wedges and will even split "real wood".
But I think a better alternative to MDF etc. may be Plastic HDPE Cutting Board.
You usually see these at the Dollar Store. 1/2" thick or better should work OK.

I got mine installed and is working very well. At first it was buzzing. It took some time to figure it out but the buzz was from the four sides of the box vibrating against the four sides of the wooden insert. It was tight but not tight enough. You can see in the pic that the screws are more toward the corners so that leaves a long unsupported space in the middle to vibrate. I solved it by using some thin foam rubber sheeting that I bought at Walmart or Ben Franklin on the construction paper isle. It is like the thin separators that come inside socket sets.
Anyway, I cut some scraps and stuffed them from the inside edge of the wooden ring toward the outter edge of the plastic housing. I got a piece stuffed in on all four sides. Then I made a ring out of the same stuff and placed it between the speaker and the box. That's all it wanted. Just some insulation between the different materials. No more buzzing and I didn't have to use any goop or fiberglass or anything messy to get a good seal. Whether or not it will last remains to be seen, though. If it starts buzzing again, I have a sheet of rubber that I'll cut up and use.
I still need to figure out a way to protect the sub speaker. The grills from my dash component speakers didn't fit it so I'll have to come up with something else.

I was thinking of buying the subwoofer that BV MotorSports posted above, but I noticed that it's an 8 ohm speaker, while I used 4 ohm speakers for the dash and B-pillars. Is this going to be a problem or anything? Or will having a good amp erase any problem that might occur (such as not being loud enough)?
EDIT: I think the stock subwoofer is 8 ohms also, so now I'm assuming that there will be no problems?[This message has been edited by rbell2915 (edited 06-10-2014).]

Would be sweet if someone would 3D print some ABS inserts rather than having to cut MDF or oak. I'd buy a couple right now.

You could easily make a mold of that part and cast it in casting resin.....Just my opinion.
