Well the time has come to lose the 50+ pound MDF box holding my 2 memphis 12s, for 2 fiberglass boxes that will fit in the corner spaces in my hatch. Here's a pic of the preliminary work going on behind the scenes... lol

So here's the corner all taped up and ready for a couple coats of resin and glass...



and after 5 layers of glass and resin, trimmed a bit via black spray paint lines....

 

holy crap, boxes that big for one 12 each, BTW how hard is fiberglasing, i would like to try it, but i dont wanna buy the wrong stuff, could you help me out, thats gonna look awsome when you get done i bet.

 

Ported boxes gotta be big.. in fact, if you go outside and measure the area my box takes up, its rather small... ill show you the old box that used to be in my car...

As far as how HARD fiberglassing is... its only as hard as you make it. If you take your time and do it right, its not hard at all as long as you keep a few things in mind.

After adding resin to the hardener, you only have so much time to work with, and that depends on how much hardener you use, and weather conditions.

Before even laying down your first layer of resin, make sure that all areas, and about 3-4 inches outward from that are completely covered in tape or whatever you use to keep the resin from getting on the carpet, like aluminum foil and so on... though i dont recomend foil. 2 layers of a good masking tape is plenty good to seal the trunk. Personally, i like to lay a single layer of resin down on the tape and let it dry... then com back and lay more resin down, put the fiberglass on it, and then what you have to do is dip your brush in the resin, and use a stabbing motion to saturate the fiberglass, and make sure there are no air bubbles.

Smaller pieces are easier to work with, because they can get into smaller corners and so on that larger pieces would wrinkle, and cause air bubbles... which are bad

Air bubbles reduce the strength of the fiberglass, smaller ones arent a problem, but any larger than a dime are some that you should try to remove. If the resin and everything dries and there is a big bubble though, dont worry, as long as you have a die grinder, dremel, or drill. Cut open the hole, and fil it with resin, and if its large enough, try to tear apart some of your fiberglass mat and mix it with the resin to give it strength, and fill the hole completely. Just make sure not to drill all the way through the box.

As far as mking the sub sit in the box, ill get to that later with pics.

Any information you need about fiberglassing a box can be found on www.caraudio.com/forum ... just look under the box construction section of the forum, and theres a sticky with all kinds of good fiberglass info.

 

OMG i just thought of the coolest way to finish this box.... carbon fiber... that would look so pimp... what do you guys think? Cuz the subs im gettin are carbon fiber....

 

that would be awsome, but isnt carbon fiber hard to lay or do what ever, and expensive. I was about to make a box for my car, and then the horible happend, my KA just died while I was on my way back from houston, So im getting a new one of those first.

I know how big ported boxes have to be by the way. my freind has 2 L5 10s in a ported box and it is huge.

I missed the part where you said ported lol.

 

mmm.. solobarics. Well, those require hella space. Im thinkin bout 2.2 cubes for each sub box. Im makin 2 of em to sit in the corners of the hatch...

 

the sealed boxes for the solobarics are tiny, .66 cubes for the 10 inch, but the ported box wouldnt even fit in my S14 trunk lol, they are at my house cause my frind donsnt have a radio, and he baught the speakers before he baught the car lol.
