Fiberglassing a box
Ok so heres the deal...I don't want my standard box anymore. It's too square and plain for me. Now here's what I am looking for. Any advice as far as what I can do, be it taking my old box and glassing over it and just shaping it, or what? Where is a good place to get the supplies i will need and just general info that would be usefull to me.

most of the stuff youll need you can get at the hardware store. its gets pricey if you buy online because of hazmat shipping on some things.
you could use your box you have now. remove of get rid of as much of the baffle as possible , then make two speaker rings, tack them together. use some scraps, glue them to the box to hold up the speaker ring at the angle you want. lay the material over the box and ring, then go to town with the resin and sanding, then a layer of matt, more resin more sanding.

you can pull the carpet, sand it with 180, high build primer, wet sand, paint and clear, then buff it out. if you have never used 'glass then you may not have the common tools to do the job and may just be a pain in the *** to you. go to www.caraudio.com and check out the fabrication section of the forum and start taking notes. the best place to get the materials is going to be an auto body and paint store. dont get the home depot or lowes junk. you usually wind up paying to much for stuff thats been on the shelf for a long time. dont use Bondo brand filler use Rage Gold. there are other tips but start with the car audio site and then ask me what you need.

Quest have you glassed a box before? If so just give me a ballpark figure one what I'd be looking at cost wise for mats. I tend to be pretty handy with my tools lol. I do all my own work on my truck and most other peoples too. What glassing tools I don't have I'm sure I can get from my father.

hmm, well i know when i reglassed a 10ft boat i used a metal stir stick (scredriver that was crap anyways), a metal scraper, the actual fiber, and then the resin, sand paper and water for the final sanding. Basically the fiber and resin came in a pack and i bought about 3 containers each about a gallon i wanna say or maybe more, and they were about 9$ each from Home Depot. It Worked great and the boat still floats.
its not a sub box, but its bigger and i did it with little knowledge or tools. i say the best way is to buy some, try it on something to get used to it (mixing the chemicals) getting the right consistancy ect ect, and then just go to town, lay a layer or maybe 2 but dont push it, then sand....alot....not heavy, but alot lightly....then repeat the glassing, and sanding.... shouldnt be too hard

a basic box should take 30-40 hours total. resin about $15, Rage Gold filler $20, sanding paper $20, you will need a good sander i prefer a right angle die grinder with a "roll-lock" disc froma uto body store or harbor freight for about $20, then if you want to paint that can range from 20-60 on average and if you vinyl look at about 20. these are estimates since i tend to use about $100 in materials, but i build solid boxes. let me get some links for you. may take me a day or so. honestly you can pull the carpet on the box and paint it the color of the truck and be done in one day.

on a side note why did you spend that much on fabbing up 6x9 boxes for an SL500? pics?

i was referring more to teh sub box in the rear, but the console sticks out so much that its more noticble.
thats edgerats truck
and as for countersinkin the amp, id do something similar to flush mounting a sub. build to "rings" one to mount the amp to then one larger than it. build it up, glass it and mount it.

Itz not that hard. I built a kick *** box that is shaped to fit my gf's PT crusier and it sounds and looks great. The "junk" that lowes sells isn't that bad. Thats what I used and the whole box cost me about 30 bucks. That includes resin, hardener, mat, and bondo. I don't like bondo much either, other stuff is better but it worked out pretty good. I say go for it. You won't regret it.

u there? i like to build mine strong enough to throw off of a 5 story building. but really you need at least 1/2" in thickness to make a fiberglass box sound good. otherwise the subs will cause the front face to resonate like crazy and will give your box a "tin can" sound. use fleece on the most outer part. and use fiberglass mat on the inside. use 1-3 layers of 1.5 ounce mat and then a good 1-2 layers of 3+ounce mat on top of that will be nice and solid. if you go sealed you may want to use polyfill in the enclosure. use my advice you will thank me later.
