The only thing is the cost. MDF costs pennies in comparison to ABS of the same thickness.

I used a circle jig. You can make your own or buy one from a specialty shop.

Alright, just like everyone else I got some Q's too.
1. What kind of fiberglass mat did you use (weight), and where in MB would I be able to pick up that specific kind?
2. How many meters/yards of mat did you use for that specific build? (approx.)
3. When applying the fiberglass mat did you soak it in resin first, or was there enough on the fleece to adequately dampen the fiberglass?
4. In a little more detail, how did you go about cutting out the fleece for the sub? Did you wait till the resin had hardened a bit, or did you cut it immediately after the resin was applied?
5. When doing your final sanding you talked about polyester filler. Is this exactly what you would ask for at the hardware store or does it go by another name? Do you coat the entire enclosure with this filler and how much is needed?
Thanks Jeff, and keep up the slick jobs! Also, thank-you very much for being so generous as to take the time to answer all these questions online!!! How to Make a Fiberglass Enclosure - Page 17 -- posted image.

i have a couple of questions
A: the way i'm gonna do the enclosures, is the back is gonna be fiberglass and the front will be MDF. how do i mount the taught fleece to the back of the fiberglass???? can i still staple it?
B: i'm scared to mount the enclosers and the amp rack in the hatch area..aka drilling a screw and possibly hitting the gas take or something else vital. any tips or tricks i can do?? how do you guys mount these things????
i'm almost tempted to use REALLY heavy duty velcro or something lol

Quick question: Is there any heating issues involved with the amp with this enclosure?

Use hot glue. Staples will not always work on the fiberglass.

Look under the vehicle and see where the gas tank is located. Most of the time it's either behind the axles or infron t of the axles. Take precautions necessary if the gas tank is under the enclosure and use shallow screws or use bolts attached to an "L" bracket that can extend to either side of the enclosure where it can bypass the gas tank.

None, the heatsink is on the top. If you have an amplifier that has fans builtin, you have to account for an intake and exhaust so you don't overheat the amplifier.
