8" Subs in Cabin
Sure... Here's the photo's I still have from the install:
As I mentioned in another post, I started the mold with a 6" PVC coupling. I cut that in half and (wish I could find the other half for ya, but I think I threw it away) covered it up in a layer of fiberglass just to close in the back side of it. Then I shoved it up in there (after cutting off the metal tab that was used for supporting the kick panel) and started packing clay up in there. My goal was to make the clay form as natural as my amateur skills would allow.
Once I got it all packed in there, I just wiggled it for a couple minutes to get it loose. Next, I wrapped it in saran wrap, but that was a horrible idea. The fiberglass just ate the saran wrap all up and made a nasty mess trying to get all the caly out.
I'd recommend Reynolds Non-Stick aluminum foil. That ought to help with cleaning out the clay once you get a layer or two of fiberglass over it all. I then just worked it slowly. Fiberglassing, sanding, cutting where I got carried away, etc. Just kept putting it in there and working it a little more until it was acceptable.When I first started the project, I told myself I should make a mold and sell them.
After working with fiberglass for what seemed to be about a year (really a week or two) I decided this would be a one of a kind!
I'll tell ya though, if there was a mold for it, I think it could sell, because once people heard how much this little 6" sub will do, they'd want one. I can clean my trunk out and take a picture, and you'd never know I had any stereo equipment. Yet, I've got two 6" subs and two amps. My install isn't the prettiest or best sounding by any means, but it certainly sounds excellent to me. Sure, a big sub in the trunk might be better, but I didn't want to give up any space. A spare tire was all I was willing to lose.
Another nice idea from our german S2k Owner:
2 additional JL Audio 8W0 (20cm) in the doors!
2 * JL Audio 8W0 (20cm)

The red interior s2000 looks pretty well done but is that sub produce any noticeable improvement?
I have heard 6" FOCAL subs (in fast we did an install with 4 of them in an Audi TT that sounded pretty good but that was a hatchback with pretty large enclosures.

Mine ended up going under the driver's side dash. There is no loss of legroom or storage space. I am six feet tall and I cannot touch it with any part of my legs or feet if I try. The 6W0 is engineered with a small sealed enclosure requirement so it is ideal for the interior of an S2K, or in a multiple-sub configuration elsewhere in the trunk.
As far as output, mine is driven very cleanly by the third channel of a 3 ch Xtant amp and I rarely have my subwoofer setting above "9" on my HU (out of 15), usually its around three to six. Plenty of low end, plenty of volume. It really helps to have it in the cabin rather than elsewhere.
And of course, I would rather have Shakira in my lap than in my trunk...

A little higher up from passenger angle, it disappears:

When you did that did you mold it around the heating and A/C ducting or did you just remove it.?
The only other air handling part in the driver's footwell is a perforated plastic air manifold used for heating toes. My fiberglass chamber included a stud on which to re-mount it forward of the chamber, as the chamber is mounted to where the plastic thing used to hang.
Up until now I have chosen to leave it out of the car, mostly due to laziness and projectincompletionitis. But in the last year or so I think the heating works just as well without it or even better. My gas foot used to get hot, amost on fire hot, with it in and now it seems the hot air is distributed more evenly into the footwell. (The downside to having your gas foot overheat is you can't really move it much while you're driving...)
So there is still room for it, but it may not be necessary in the first place. Certainly a truncated version would do the job just as well.

Man, LATEOTT, I'm just now seeing this. Gotta love old thread subscriptions.
That looks excellent! I know it sounds good too. Makes me want to make another box for 2 in-cabin subs.

I think I never properly thanked you for the inspiration--THANKS! I was very grateful for your detailed photos and helpful suggestions with fiberglass. If you look at my install thread, I also followed your use of a chunk of plastic pipe for a speaker mounting surface.
Before I started I did a lot of poking around in the passenger footwell. For some reason I also poked around the driver's footwell and found a bunch of space under the dash once I moved a couple of things. Since this was a custom fabrication anyway I decided to try it there and it worked fine.
It was my first experience with fiberglass, but a great project to learn on.
One thing that our two installs (taken together) proves is that it's possible to place TWO subwoofers bilaterally inside the cabin with minimal intrusion. One seems like plenty to me, but two are obviously possible.
Thanks again!
