Please do post build thread when you do. 
I like the idea of an 8" sub down there. Some of the setups I saw look just like stock.

I built an enclosure with 8.5" sonotube, 12" in length, yielding .33cuft, perfect for my Polk/Momo 8" sub. This mounted in the same location as the factory sub. My car is an 86 (non A/C ) and the assembly attached similarly to the sub shown...no holes needed to be drilled. This enclosure is not visible from the passenger seat.

sorry, no pics, but I did get the idea from others on the forum. Try a search, you should find the details. It was really an easy project.

This is a good idea but with 100w I can see the flimsy plastic enclosure flexing a lot and adding distortion. Maybe not noticeable to many but will be there for sure. Would be nice to reinforce the stock enclosure.

I just did this to my own, using the suggestions here and from others on the forum.

It sounds really nice, even when pushed hard. The bass is not as deep as it would be with a larger speaker, but for my needs, it sounds just fine.
You do make a good point, by suggesting the plastic might be an issue at higher levels. I was worried about this, and about buzzing. I'm shocked by how clean it actually is. But in no way is it as good as a quality wood enclosure. I don't hear a ton of secondary harmonics, but the sound is a bit "colored" as compared to the nice warm sound a wood enclosure can provide.
I also use a lot of poly fill to compensate for the smaller enclosure.------------------

Doesn't seem to be a problem - likely because it is ported. Now if it was a sealed enclosure, I could imagine it would eventually crack from flexing under pressure.

OK, I made the adapter just as you have pictured, I let the silicone dry overnight and will assemble today. I got the polyfill at WalMart. You say stuff it loosely. I guess as long is it is not packed tight I will be OK. I also cut 2" off the plastic tube. I will test it out today.
I have high hopes for this as to date my subwoofer has done nothing more than fart a couple of times. 
Can someone explain something? If sealing around this mdf adapter is important why was the original metal piece in there full of air gaps? Not sealed at all. Air/sound could pass around the speaker or through the bass tube.[This message has been edited by sjmaye (edited 01-18-2009).]
