Fiberglass sub enclosure

Recommended Posts

Hey all, so I figured I would try my hand at building a fiberglass sub enclosure in my 05 obxt. I've been an audio/ remote start installer for years, but I've never built a single box before this. I really wanted to have a box that would fit in the hatch behind the wheel area that didn't eat up my wife's valuable storage space and was a bit sad to find that jl had discontinued their stealth box for this year of car.

 

So here's my attempt!

 

First I cut a template of my box out of cardboard to get an idea of what I wanted it to look like. I wanted to maintain use of the cargo net so I made sure to notch the bottom corner to accommodate it.

Then I used masking tape, plastic and newspaper to mask off the area I would be fiberglassing.

And started slinging resin and glass

Back of box hard enough to remove

Next was to cut the face of the box out of mdf

And to use it to trim the glass portion of the box

Then I glued the box together using kitty hair and resin

Time to throw the sub in the box and check for leaks!

Now I just need to grind off the excess material and carpet the box which I probably won't be able to get to till Tuesday. The box so far has taken me about 10hrs to complete and probably has about another hour left to be a finished product. I would definitely like to do this again and will probably make another box with a port and the proper volume for the sub. Let me know what you guys think!
