i was gonna do the same, but after realizing there wouldnt be enough room or airspace in the box for what i wanted to do i decided to order a kicker solo baric 12" l7. im gonna build a box and put it in the middle of the back seat. 2 10"s under the seat can be done, but it would be a pain in the butt.

Cost me about 300 canadian but it was my first time with fiberglass so I could do it faster and cheaper next time. Most shops wanted like 800 to 1000 for one. It is 48 inches long, 10 inches deep and 14 inches from front to back of box. Let me know if you need any more help!

Just buy a thunderform box it sounds great in my truck and was faster to install.You could always change the subs. My amp is 800watts with the two mtx subs and it sounds like two 12 inch.

If JutDakota02 was interested in only spending $400 for a complete setup i'm sure he would but most who enjoy good sound won't be satistfied with a thunderform. My subs/Amp/Box alone cost me $1500 and if i went with a thunderform it would of cost half of that but i wouldn't of been as happy. There are very few subs that would fit in the thunderform because most subs have to big of magnets!

A friend of mine builds custom boxes, and we built a downfire box under the seat for 2 10W3's, all we had to do was take the hinges of of the back seat for more clearance and then mount them to the top of the box, it sounds great and everyone that hears it thinks its at least 3 12w3's, i have em running bridged off of 1 1000watt memphisD amp.

What better sound deadening than concrete? Im on a buget and cant afford a thunderform, But also dont care who can hear my system, just as long as it sounds good to me. So Im installind 1 8" sub in the original plastic tray under the back seat club cab. to deaden it I simply layed a 1/2" of concrete in the one compartment ( so to still have my jack ) and the lip where I guess there was a plastic cover? (Not mine) is perfect for a nice piece of 3/4" mdf. let me know what u think. I can send pics with an address

I built a box for (2) 10's under my rear seat using
fiberglass and MDF. I've got a gen II but the concept is
still the same. There are a ton of pics of the box
construction on my website. Check it out...maybe it will
help you out. Feel free to send me an email if you have
any questions.

Budget is right, the perfect enclosure would be shaped like a ball and made out of concrete. I would like to know how the 1/2" concrete is holding up with out cracking?? Did you add any hardner to it?? I would like to see some pics.
You can see my 2-10" enclosure I built for under my rear seat at my web site. It only cost me about $45(cdn) to do. Plus I have other Dakota installs using the same enclosure idea on my site.

bw1199 how many watts is your set up? I have been toying of doing what you did but have been wondering if you have any spl numbers?
I have two really nice subs now and no space and I'm thinking of replaceing them with 4 10's of lower level (due to $$$$$ issues). as in 4 300 watt or so subs.

An ideal speaker cabinet material would be very stiff, so that it would not tend to move with variations in box air pressure. It would also be very well damped, so that if it ever does deflect from air pressure, it will come back to the original position without resonating. It would also have a very high resonant frequency (supersonic), so that low frequency box air pressure would not cause it to resonate. An attractive material is preferred, and additional credit is given for a material which is easy to cut, glue, and finish. A great material would be cheap, too. Finally, it would be nice if the material were light, because we all have to move our speakers sometimes, and it's hard to appreciate good speakers with a sore back.
With all of those attributes, it would seem that no material is perfect. However, there are many materials that have enough of the above good attributes to make excellent speaker cabinets. Yet each has advantages and disadvantages.
In the list of good speaker box materials below, letters are used to indicate which attributes the material possesses. S = Stiff D = Damped H = High Resonance A = Attractive M = Malleable C = Cheap L = Light
MEDIUM DENSITY FIBERBOARD (MDF): SDMC This is the most practical material for quality speakers. It is resists interanal resonances better than plywood. Most lumber yards can special order it. It cuts very nicely and has a smooth surface. It takes veneer very well. However, bring a helper when you pick the stuff up. One sheet is very heavy. MDF is harder on tools than common wood, but easier than particle board. This is the material that many great speaker makers use. $45 for a 4'x8'x1" sheet. Density: 50 lbs/cu ft.
POLYCARBONATE (LEXAN): DMA clear or solid-color polycarbonate box can look strikingly good. However, this is not a cheap material. To locate it, look in the classified directory under PLASTICS. $400 for a 4'x8'x0.5" sheet. Density: 75 lbs/cu ft. Acrylic (Plexiglas) is cheaper than Polycarbonate, but weaker and poorer damped (not recommended).
PLYWOOD SHEETS SPACED AND FILLED WITH SAND OR LEAD SHOT: SDAMC If you have time on your hands and want a great impractical box, try this. Make a simple box out of common plywood. Then glue cleats on the outside of the box to space the outside plywood from the common plywood. Glue hardwood-veneered plywood to the cleats and pour sand or lead shot into the spaces between the cleats. It won't be light, but with the filler, it will be extremely well damped. In addition, if you use strong cleats and glue well, the box will be extremely stiff. Be sure to sterilize the sand in your oven before putting it in the box. This prevents the growth of mold and other extra sonic impedimentia.
ALUMINUM SHEETS FILLED WITH ALUMINUM HONEYCOMB (Aerolaminate): SDHL Airplanes use this material for flooring. The next time a plane crashes in your neighborhood, see if you can get the wreckage for your next speaker project. You can't get a better, lightweight material. If you're really ambitious, you can make your own sandwich out of high-quality plywood faces and a thick honeycomb core. You will probably need an epoxy to glue the honeycomb to the plywood. A home-brew sandwich is easier to cut and glue than Aerolaminate.
FORMED CONCRETE: SDHC Not a good choice for car speakers. There are tricks to working concrete, such as to cast braces, rebar, and steel-wire right into the mix. Also, some concrete is better damped than others. Remember to oil your concrete forms so that they can be removed. Most concrete speakers use an MDF front panel, but you can pour one if you use cardboard tubes or plywood rings to mold the concrete into the shape of a speaker cutout. Alternately, you can make a common veneered plywood speaker box and cast concrete inside it for stiffening. Any box can be improved by making the walls thicker, by bracing the walls, and by stiffening the walls. The stiffness of a material goes up as the cube of the thickness, so a slightly thicker material is much stiffer. A thicker panel will also have a higher resonant frequency because the stiffness goes up faster than the mass. Consider lining the inside of your speaker with ceramic tile, attached with fast setting mortar. You can get tile remnants cheaply. They are easy to apply and can be added as an afterthought to an imperfect box. However, be sure to attach all braces before tiling, because it is hard to attach anything to tile. Also consider bracing any weak parts of the box. For example, all joints will benefit from a wooden cleat. The back of the box will benefit from stiffeners where the speaker terminals are attached. Most importantly, brace the front panel, or make it out of a double thickness of material
