I built this sub enclosure for my daily driver. The second sub (IDMAX12V3D4)will be here on Thursday. They will be getting about 750W RMS each from a RF10001BD amp. I need to seal the bottom of the enclosure to the top. As you can see, it's all just open right now. The fiberglass doesn't have to be pretty, just functional. I'd be willing to pay for your experienced help as I've never worked with fiberglass before. I'd like to work on it either Friday or Saturday during the day in St. Pete.

 

theres not much too it for something so simple, just lay three layers of aluminum wrap and lay the resin hot(as in lots of hardener so it dries in ~20 mins) onto some old tshirts cut into 10"x10" blocks.

Once you get the bottom layer, pull it out(it will take the aluminum with it) and recoat several times.

Coat the bottom of the wood with fiberglass and let it dry.

Once you have a satisfactory layered bottom, lay the top on and use more shirt to make the seam to the wood top.

I would be willing to perform the construction for you but since I get the feeling you want to do it yourself It wouldnt be worth it to pay someone.

 

I don't so much want to do it myself as just kinda help out and watch to learn.

 

$120 parts(55)/labor45/travel(20)(its about 90 miles from me) and ill complete the project in front of you.If you have the resin, some wood to brace, aluminum foil, and mat subtract the parts *edit* miscalculated resin cost

 

You've got tools and a garage?

 

What tools do we need? Yes, I have a garage.

How long are we talking here? Start to finish.

 

Tools-wise, you're going to need some wood working tools...atleast a jigsaw, 1.25" screws and screw gun. Atleast a manual staple gun (and staples), preferably an air nailer and air stapler, and some sharp scissors.

Supplies-wise, you'll need ofcourse fiberglass resin, mekp hardner, woven fiberglass matting, atleast a square yard of fleece or someother absorbent fabric, several disposable mixing cups, several pairs of rubber gloves, several disposable paint brushes, some wood atleast 3/4" thick, aluminum foil, and a six pack.

Also, on a side note, I'd wrap the carpet around and under the current false floor you have shown in the pics...it'd look alot cleaner.


Start to finsih, I'd say it would take about 3-4 hours.

 

Honestly, I'd see what kind of space you could get boxing it off first and having a 'glass bottom only. Waay less 'glass work and less hassle.

 

glassing the bottom as opposed to just coating the whole trunk isnt much more work. Since its all gonna be hidden under the face it doesnt have to be extremely even layerd. Just work it hot and brace it good.

 

Time and materials say otherwise. @ a 2% mekp mixture you get about 20 minutes of working time and 10 of drying time. at that rate,with my method, I've done it to my own car in about 2 hours. Less Surface area to glass, less hassle with bracing and thickness, less glass, less brushes, less resin, less hardener, and I'm willing to wager youve got the scrap mdf around.
