Made my own fiberglass enclosure SWEET!!!

Took some pics today. I finally tried my hand at making a fiberglass enclosure for my 3rd Gen. It sounds absolutely incredible. I made the lid and frame out of 3/4" MDF and molded the fiberglass to the floor under the seat. I lined the carpet with aluminum foil so the glass and resin wouldn't destroy the interior. Then I laid the glass on the floor with the frame in place. The rear seat was removed befored I attempted this if you are wondering. I counterbored the hole for the sub .300" in a CNC mill to sink the sub in to the lid for seat clearance. I also machined a pocket in the lid for an aluminum plate the I machined the Alpine logo in, press fit and glued in to the pocket and then coated the hole enclosure with a spray in bed liner for durability. I filled the enclosure with water and did the math and it ended up yielding 1.303 cu. ft. I'm running a Kicker Comp CVR 12" DVC 4ohm sub. I am runng a Alpine MRP350 Amp to the sub @ 2ohms 350RMS 700 peak. And am running an Alpine MRV F353 V12 5 channel Amp for the components. The fiberglass enclosure is strong enough to stand on at any point with my 245lb frame on it. So what do you all think? This was the first time I ever worked with fiberglass. This sub was literally rattling my garage door from 30 ft away bumping Bass Mekanik.

Good job on the box. Bass Mekanik brings back alot of old memories of my first system with (12) 15" Pyle Pro woofers and Linear HCCA amps.

No problem bro, I'm 36 and still lovin the bump. It was hard building this with a 6 week old son. I could only work on it a half hour here an hour there. It's finally finished though. It sounds freakin incredible and drops real low. :rck:

Thanks!! Man, I learned a lot about working with fiberglass on this one. Before I built it I got some quotes from the local shops around here for a fiberglass enclosure. They wanted anywhere from $700 to $1000 to build this box. Screw that!! That was enough of a motorvator to get me to learn how to work with fiberglass. :IDEA:

How much did you put into materials?
I like people who say "I built a fiberglass box for $25" I always ask them where they bought that quart of resin from :D. I know that when I made the mold from my quad cab I made the layup .5-.6" thick and I had 8 layers of cloth and 4 gallons of resin at $40 a gallon. I usually have $150-$250 in materials to build a fiberglass enclosure of proper thicknes.

I had a chance to hear that thing go boom.

You know it has some kick when the garage door starts to vibrate.

So, when are you making me one? You can machine me a Grant211 emblem in my box.
Thanks. LOL!!!

Just curious what do you use to determine proper thickness of a fiberglass enclosure? Or is there a industry standard saying all fiberglass boxes should be x amount of inches thick?


SHADOW QUAD CAB Great looking box you show signs of wood working skills cant wait to see pics of when you decide thats not enough bass and go bigger. :rck:
