have you checked any local shops around you, most can do custom installs. they are pretty expensive, but im sure after you have a box built online and then pay for shipping you will probably only be 50 dollars short of what the shop would charge(just a guess tho) what are you looking to do, swez and ttocs can help you to build your own box, they have lots of experience. just post what you want to do, how many subs. what brand. things like that so they know what you have to work with. good luck

If you go with a prefab box, q logic makes good ones. I recommend a custom by all means. Every speaker requires a different airspace on the sealed side, and ported side where applicable. Some are not recommended to be ported, some only sound good in a ported box. For a truck like you have, ported boxes are the best way to go due to limited space for a box.
If you buy a prefab box, make sure it is within the cubic feet recommended for your speaker. When I built my own bandpass box to the specs of my jbl 12's, I doubled the volume, and at least tripled the sound quality I was getting before.
It does make a difference!!

i can build my own box thats not really a problem i can even get a sub zero box custom made for my speakers for under 50$ but i want something thats as pleaseing to the eye as well as it wounds good right now i have a box thats pretty much perfect for my speakers but it looks like crap having a box just laying behind my bucket seats in my truck. i want it to look like its part of the truck. and i have seen custom molding and crap in other trucks that just bleane the box into the truck. i'm willing to pay the money to have this look good i just need to find a place that well do it. the only place around here "portland oregon" that i can find to do it is car stereo city and well they dont have the best rep not to mention they order the stuff from another company and then sell it to me so i'm paying a decent mark up for gear i would rather by striaght from the place that makes it.

Am wondering if you can partner with a guy that is familiar with custom fiberglass body work on trucks and cars? If you can find a guy that is willing to fabricate something that looks good and also sounds terrific, for your truck... you have a plan to go on.
You may want to approach him as a side job where he gets all the cash in his pocket w/o the shop overhead fees included. It may take a bit longer for him to design and fabricate a pod for your sub(s), but in the long run.. you'll get a professional looking job at a fraction of the cost this way. Just be sure he understands the acoustical and esthetic goals of the project and give him enough front money for materials.
To keep him motivated, follow up with modest payments toward the balance and maybe a performance bonus at the end when you are well satisfied.

I have seen fiberglass sub boxes before but never really understood them is it all fiberglass? and that sounds ok if so? i always guess i assumed there was a wood box under the fiberglass shell. that sounds like a really good idea. i may even know someone who could do that. thank you very much as always... oh btw 1 more question i did find a custom box for my truck today online it has both the speakers facing the floor though and only 3 inches from the floor at that. is that enough room for them to sound ok or is it going to sound mroe muffled?

The down fire subs do work. MTX Thunderforms are made that way and they only have a few inches of air space between sub cone and carpeting. That means a fair amount of bass wave energy is reflected back to the cone.... more distortion.... less SPL is the net effect unless the bass is deflected via a chute. Even then, the chute has to have adequate angle (curved is best) to prevent cone wave reflection problems. (usually rigid fiberglass for the chute)
Fiberglass bass enclosures work well if they are designed properly. I have install fiberglass bass loaded horns with 15" woofers in a large sport arena. They sounded great and very powerful too. (2000 RMS plus to each) Heavy as all get out... but sounded very good for high SPL and a horn design made them super efficient as well. (~110dB/1 w 1m) These were mounted 30 feet up in the air and a pair of them gave plenty of SPL to fill a room the size of 3 basketball courts. One challenging install that tuned out to be for 2 guys.
In short, fiberglass sub enclosures (3/8 - 1/2" thickness) are plenty strong when molded properly. Talk to your friend and see if you guys can come up with a plan and design that meets sub criteria and fits well into your vehicle. Very little wood is involved, depending on the design. Fiberglass in that thickness are more than adequate for sub applications. It all in the molding/shaping that does the trick.

I have dabbled with a small piece of heat mold fiberglass that my friend had after his company finished a job for GE. It looks like a fiberglass/plastic mix, but bends easily with a little persuasion from a torch. You may be able to get something like that to work for you.
