Hey, I always to see what someone could do to this car, I plan on doing something myself.
I saw this, and I was confused..
Is his whole car fiberglassed?
And when going about making custom fiberglass interior, how does it connect to the car?
I'd assum you'd take off the old plastic interior molds and use them to make your fiberglass mold around. As for attatching it to the car, use the same screw holes as the plastic molding?
I'm a fiberglass noob, but it's definatly something im excited about doing, I have a bunch of crazy ideas, I just need the eduction.

Dude, you win the award for link of the week.
That guy is living the dream. "Plan it, Do it, done."
Yea, he is using fiberglass to mold and shape to his heart's desire.
Since you are new to the scene and industry of this much appreciated art, I recommend you look at the sticky topic "how to make a fiberglass enclosure." Although that is a particular type of project, the foundations and principles for almost all fiberglass projects can be seen in that one how to.
I have not failed. I've just found 10,000 ways that won't work.

Thanks :)
I'm still studying up, but I have the basic idea of things, I just need some money so I can start practicing.
I figure I'll just make a bunch of enclosures the will fit in the back of s13 hatch trunks like this one..

I want the box so that the back seat closes flush with the box where the seat meets the different fabric. I'm not too sure how i'd go about building the box, but im gonna shoot, maybe somneone could draw some work plans on those pictures for me? that would be a big help.

The enclosure size will vary in accordance to the optimum volume required by the subwoofers that you choose. Don't try to make the enclosure size fit the vehicle as this will make the subwoofer sound like crap if in the end the enclosure is too small or too big. You can cheat by filling it with Dacron filler if it's too small or add to the enclosure if it's too large, but plan ahead and you won't need to do either.

Not to poke fun, but I have to know... did you mean that the other way around... "add to the enclosure it is is too small, and use Dacron filler if it is too large" ?

Yea, the guy on that link is doing some wild and crazy stuff, like you said Melted living the dream. I just had to bookmark that page.

Not trying so side track the topic but what do you all think he used to mold the fiberglass on top of, wood?

Honestly, my gut feeling tells me he used cardboard (or a similar material), like from a box, but sealed it so no resin or other liquid would leak into it.
One method I have been wanting to use for a while is how Steve Brown (Fabricator of the 2003 Alpine Civic Si) does it sometimes, and that is use foam blocks. Cut, sand, sand, cut, sand to get the shape you want.
They even have foam you can use to fiberglass over, and then after your fiberglass structure has cured, the foam can be dissolved using a liquid chemical.
Yea, that profile on cardomain is crazy. I do not have an account there but was going to make one, just to invite him here, or to at least see if he knows about us.

Hey how is everyone... this is aftercrash... the owner of the 240 in ?... I have to thank th3c3z for the invite to this page. As for living the dream.. I think that is the best compliment I have ever received for my car, and I am humbled by it. So the question seems to be what did I use to get my shapes... believe it or not I used very little cardboard. I used 2" close cell foam purchased for a local bedding store, i paid something like 32.00 for a 48x24x2 sheet.  Then I sprayed adhesive on the car and outlined where I wanted to make my cuts. then after all was said and done I then taped over the foam with 2" masking tape and applied turtle wax (about 6 coats) and then glassed the tape.  As for my glassing process...I used fiberglass clothe 1st , then when that dried I came back over with 3 layers of 6oz mat.  Once that dried I removed the mold from the car and gutted all of the foam from the underside of the glass. Then simply do the same to the opposite side. Or if you have more time on your hands do both sides at the same time to ensure its even. 

My build up has been about a year in progress and i am currently waiting to get the car back from the pro shop when they finish with the engine. I actually did the labor of the install but know nothng about wiring so when I get her back I will finish the interior.  My current plans are to install my amps in the custom glass enclosures like you see on my acrdomain page, but in the spot where the rear windows used to be i will place (2) 4in mid bass drivers directed towards the front seats, my Co2 bottle in the middle of the two seats... and as for my custom 12" enclosure... your gonna have to keep checking back but it's gonna be crazy!!. 

In no way am I a pro at this stuff so if you have ?'s or some good advice feel free to let me know... again thanks for the invite!

And to piggy back on Velocity  another you could do is get a free air sub, this will allow you to make any shape of enclosure you want, the draw back will be that you can only use free air and you may not acheive the db you are looking for.

Also to piggy back on this.. you could always get a free air sub but the draw back is you may not get the db's you want
