Theres no point in a full glass box in this application, plus you would be elimininating 75% of the work right there. You can have your MDF slot port on the bottom of the front if the box is going to butt up against the backseat and still make it easy.The fleece- once the framework is done you basically stretch it over, keep it tight, staple and trim. Use alot of staples.A gallon of resin comes with 2 tubes of hardener. Mix 1 quart resin with a half a tube (11mL) of hardener. personally I mix a half gallon at a time. Its good to have a pitcher with a spout because the resin gels pretty quick so its important to get it on quick, with a pitcher just pour that ish on and spread it with a chip brush instead of dibbing and dabbing. Its important to really soak the fleece, especially where it contacts the MDF, so go over the whole thing once, mix some more, and go over it again, and again. It takes more depending on how tight its stretched, but when the fleece has a nice 'glazed' look, youre pretty much there.Let that harden a day, im not sure what tools you have but a sander is handy, dual action or even a mouse helps. When the resin cures theres a layer of surface wax and that has to come off (basically sand off the shine). Also sand off any loose fleece hairs/clumps if their there but if you hit it with enough resin there shouldnt be much. You want it as smooth as possible so theres less chance of air bubbles forming when you start glassing.The glass work is kind of tricky, but put on some good gloves because this is the best way since you probably dont have fiberglass rollers. Take your time tearing up your mat, using bigger pieces on flatter spots. Plan out which piece will go where, dont overlap too much because that'll just make high spots and vice versa. Get a pan, mix some resin with a little less hardener, fill the pan. Dip the pieces of mat, let them soak and drip, and stick them on but try not to get air trapped underneath . Use your chip brush to spread out the excess resin and work out the air bubbles if any (with a good dabbing technique). Layers depends on the weight of mat used and shape of the box but youre going to want a good 1/4" at least.I like to make my sub cutouts after the filler and primer, a rotozip works best. Make the cutouts too early and its likely youll make a mess on the rings. You also might want to reinforce the MDF/glass seams from the inside considering youre using HDC3's.</blockquote>
