I read somewhere that you can use fleece material instead of the mat when fiberglassing. If you do the first layer fleece, would it be possible to add in the mat for additional layers? Or is the fleece idea just a waste of time. by the way its just the bottom i want to do in fiberglass. the rest is all mdf.
also i want to know because i have a 99 with that real contoured bottomed and i tried with just the mat this summer but it was a mess and didn't work so i made one of just mdf, huge, but sounded awesome. so now i want to retry and take my time with the process, but please give me some help. thanks everyone

Curtis, fleece is used to form a complex shape to build fiberglass on top of or underneath. The fleece is thick and sucks up a lot of resin which making a rigid base to build the additional layers on top of. Your not going to need fleece for building a fiberglass bottomed box, plus, fleece is not strong enough to be use in place of fiberglass.
To make a glass bottomed box, build the sides of MDF, line the truck's floor (foil, saran wrap, tape, something the resin won't stick to) and apply the first layer of fiberglass and resin to the floor and MDF sides. Once this has cured, 30 min - 1 hour, pull your mold and start applying more layers of fiberglass out of the truck.
Do yourself a favor and visit a fiberglass shop to get the supplies since they carry thicker fiberglass than you can get at auto stores or home centers. I used 3 oz glass mat on my 12" QC sub box and it only took 5 layers to get the sides 1/4" to 3/8" thick. If I would have used the 3/4 oz stuff from Home Depot or Wally World it would have taken more than 15 layers to get the glass that thick. Using cloth instead of mat will be easier since mat does not bend around complex shapes as easily as cloth, but mat is stronger than cloth. I used both on my CC boxes last year, mat on the flats and cloth on the curves.

There were some links for building fiberglass sub boxes.

DSW, Thanks for the info. I noticed that your box goes all the way to the side of truck and I was wondering how you did that. I bought a piece of mdf from home depot but its only 49" wide which unfortunately doesn't reach all the way to the sides of the truck. I was thinking of making something to replace the cup holders but I was just curious as to how you made the box that wide?
I was planning on making the whole bottom fiberglass simply because I heard that the more space the better. Although I like the individual compartments for the subs then leaving room in the middle. So I want to place the amp in the middle which shouldn't be too hard.
Finally I was wondering if you have any rough dimensions, if they were on the page before I apologize and go back and look but right now I am pressed for time. Thanks alot for all the info already though, that box is amazing.

Amazing and for sale, the boxes that is, I totalled the CC truck last month and got a QC. If your interested let me know. Any who, enough for the sales pitch.
There are 2 seperate gloss black boxes roughly 19"x20"x5" connected by a grey carpeted filler panel. The filler panel is less than 49" as I had some trimming done at the ends ao it would fit snug. The sub boxes fit against the side walls so there's planty of room in between for whatever.
Make sure to build the boxes to the correct air volume for your speaker, more air volume isn't realy better unless the speaker is designed for more air volume. My sub boxes are .7 cuft which fits a lot of 10" subs, but then again many 10" subs require more air space, it all depends on your subs specs. If your sub says 1 cuft is optimal build it to a little over 1 cuft, you can always add something to the interior of the box to reduce the volume, but you aren't going to add volume. It's difficult to calculate the volume of a box like this, I used water, packing peanuts and sand to see if they all jived, they were all realy close.
I have the boxes packed for when I sell them, otherwise I would give you some measurements. Oh, I had some templates from when I built the boxes, if I can find the templates I could Email the templates over. Let me know if you want them, boxes or templetes. Just a headsup, the boxes are realy complex, many peices, angles and oddshapes,,, they are dificult to build.

BCdakota, I noticed you were inquiring about subs and a box from another post. Why not buy the ones that I took out of my old 00 CC, shipping too much from the US to BC? I am selling the sub boxes, RF XLC 10" subs and filler panel since they won't fit in my new 03 QC. I don't know how much they hit you with going across the border, but I'll consider a reasonable offer.
If you want template copies I'll look around for them, they are burried in the garage somewhere.

Honestly, I wouldn't know where to start as there are so many variables.
What are they worth?
How much shipping will be?
Exchange rate?
Duty?
See what I mean.

I have started builing my own this afternoon. So far I have completed the bottom and the front. I am custum fitting each piece as I go. I did not take advantage of the shape of the floor by glassing, I just leveled off using blocks to create a nice flat surface to start with. Out with the back seat all together.
Does anybody know how to remove the back rest in the clubcab? I pulled on the bottom corner and broke the tab in behind. I don't want to destroy it as I might some day down the road decide it to go back in.
3/4" mdf is what im using and I might use a combination of paint and carpet to finish. In the end i'll have room for up to three 12" subs but will probably only install two. Still not sure on 10's or 12's.
When the back rest gets yanked what would be a good material to use to create a 'finished' look for what metal is exposed?
