Finally My subwoofer enclosure project is finished!! I fiberglassed the whole thing myself. Although I had a body shop paint it for me. It really wasn't all that hard. I only have one pic of it but I will try and get more!

Looks good, I would've painted it to match the car though

Well I am planning on repainting the car and that is the color I want to paint it so I was just kinda thinking ahead.

HOLY SHAT! Working hatch struts on a DSM! Nice job tho, looks great!

thats what i was thinking when i saw it.. hmm odd color choice...HMMM!!! theres nothing holding up the hatch... *looks again* nope no sticks..

That color is actually a mix of a lot of differn't colors. I will eventually get the car repainted the same color.

Looks very good, Nice job

hey do u have a wing on ur car... cuz i have the gtr wing and my trunk wont stay up for nothing....

I have the GTR wing. So far, so good.....my hatch struts are still working

I have actually have had 3 differn't wings on my car. I had the stock N/T wing then I had (please forgive me) a "Big" wing, then I had all the holes welded shut and repainted then I had a 2g Turbo spoiler put on. That is what I have now.

How hard was it to do the fiberglass yourself?

I FIGURED IT OUT...he has one hand holding the thing open and the other to take the pic....thats how it stays up

Don't tell anyone, but the hatch struts on my 1G work

That enclosure looks very cool, and I'm sure your car will look hot when you paint it that color. So give us the info and how to's. Don't hold out on us, you know better than that. Where did you get the fiberglass and resin?

Mine was built in 12/89, original hatch struts, perfect working-condition.

I actually sometimes struggle to close the hatch if i have my hands full sometimes.

I am in class right now when I get home tonight I will write up the directions on how I did it.

Alright the Instructions:
you will need - (all can be found at Home Depot, Lowes, any hardware store)
Large can of resin
Large can of bondo
Fiberglass Mat
Gloves
Spreaders
Paint Brushes
Mixing cups
Plywood
MDF (Medium Desity Fiber Board)
Sand paper (Roughest grid all the way to the smoothest grit)
Fabric ( Any kind will do)

You are first going to make a template of the trunk area. Do this however you like, I just cut it out of card board. Next you want to Trace that onto a piece of plywood then cut it out. Next measure ( From the outer edge of plywood in) about and inch and a half all the way around the paremeter. Now cut out the center. you should have a piece of plywood in the shape of your trunk with a hole in the center. You now have to get out the fabric.(This part can take a while to get right) staple the fabric around your plywood frame you just made and let a little sag in the middle (This will give you the dip effect) once you have stapled and restapled a million times to get the shape you want right cut out of the extra plywood to rings the size of your subs measure in an inch and cut out center. now lay the rings were you want on the fabric and staple the from the bottom so you should have a piece of fabric with two (or however many subs you have) rings attached to it. Fiberglass time. Mix up your fiberglass resin with the hardener it came with and start by brushing with your paintbrush the resin onto your fabric until it is completely covered (leaving the fabric inside your wood rings dry). Now lay down your fiberglass mat onto the wet fabric. push it down so it sticks to it and lay another layer of resin onto the mat. While putting on this layer of resin brush it all the way up the mat to the inner parts of your rings (this will give your subs the pertruding look). wait for it to dry. Flip your mold over and do the same process to the bottom. When dry you should have four layers of resin and 2 fiberglass mats on your mold. It Should be very stiff. now cut out the middle of your rings and sand down the edges of your mold and inside your rings. Also sand down any imperfections on the top side of your mold. Now, mix up your bondo with the included hardner. Spread the bondo onto the top of your mold in smooth fine layers using a spreader. allow to completely dry and add another few layers.Now starting with your roughest grid sandpaper start sanding. gradually work your way to the smoothest sand paper. This could take hours. Took me 3 days to get it right. If you have made it this far you are almost done. Now make sure all your little pin holes are filled in and it is completely smooth. Paint it. Either yourself or at a bodyshop like I did. drill holes for the subs. Make boxes out of your MDF board underneath your mold and attach subs. Viola you are done.
I wrote this in a hurry so I might have missed somethings so if something dosn't sound right feel free to pm me and ask me questions.
one last thing. It sounds difficult but it really isn't. and don't listen to the people on here that say it is to hard and not to even try it. Try something small first if you are not sure about it. This was the first thing I have ever made out of fiberglass.

I'm a little confused on this towards the begining with the cloth and placement.

Any chance you have pictures to clarify or could you make diagrams?

Here this is a quick diagram. I am no artist at all! but I hope this clears that up a little.

so let me get this right....on top there is a layer of resin, then fiberglass, then resin, then cloth, then resin, then fiberglass, then resin again? You leave the cloth in it?

you got it. imagine a sandwich

resin
mat
resin
cloth < -- cloth in middle
resin
mat
resin

Yes you leave the cloth in
if you want it even stronger you can add as many layers of resin and mat as you like.
when done apply smooth coats of bondo on top layer. I know it sound confusing. Sounded the same way to me as well. But when you actually are standing there with the supplies it all makes sense once you start.

I gotcha now

thanks for the info. BTW..where did you get the supplies? Specifically the fiberglass cloth and resin. (I know home depot for the wood...)

I got all my stuff from home depot. you can get EVERYTHING that you need to do this project with from there. (except the cloth) but you might be able to find something there to use in place of that even. For the resin and mat look in the isle were they keep the wood stains and paints. If you ask someone they can tell you. to tell ya the truth you can get the mat and resin from walmart. Same stuff to. but it cost about the same so you are better off just going to Home depot.

almost forgot. when you are ready to lay the bondo. I would suggest going to walmart for that. It is cheapest there. and you get a BIG can and belive me if you do the same thing I did you will you just about all of it!

This is very good info.

Create another thread with just the instructions and I can move it becasue it looks like a good tech article.

ok...i wanted to try this but my concern/question was how does it sound?... i was reading up on subs and stuff and they have open boxes,etc and they talk about it being a specific size and stuff...so how do you kno how to make da actual box?
