Well I finally got sick of my regular old 3/4 inch mdf enclosure taking over my trunk, and I decided to do something about it. Over the course of the last week, I have been working on my custom fiberglass spare tire well enclosure. I hope you enjoy checking out the pics. First off let me warn you, this is my first fiberglass enclosure, so granted its not perfect but I will explain how I did it anyway, just incase anyone wanted to know.
I lined the spare tire well with aluminum foil and held it in place with electrical tape.
I put one layer of fiberglass resin and mat in my trunk. I only did one layer in the trunk, and the rest I did in the backyard because fiberglass smells so bad, its ridiculous.
For the top of the "box" I used the piece of fiberboard that was originally over the spare tire. I put about 7 or 8 layers of fiberglass over the whole thing.
Then I took a piece of 3/4 inch mdf and made a cut-out of where the sub would sit. I had to use 3/4 inch mdf because otherwise the sub wouldn’t fit because it was too deep.
By far the most frustrating part of this installation was trying to get the enclosure to fit in the trunk perfectly. It didn’t, It sticks out like 1 inch, but with the carpet on you can hardly tell. In order to get it down in the spare tire well, I had to practically jump on top of it, not a simple task. There was also I lot of sanding involved... Once it was in I drilled holes for the wiring, and carpeted the whole thing with some carpet I picked up from home depot, and I also used a can of headliner adhesive from Murray’s auto parts store to hold the carpet down.
Hope you enjoyed looking at the pics! The whole thing took me a total of 4 days, and the cost of supplies were as follows:
Fiberglass resin: $40 at home depot
Fiberglass mat: $30 at home depot (7 packs)
Cheap paintbrushes: $2 at dollar store
Gloves (you need dozens of pairs, fiberglass does not come off of skin easily) $5 at home depot
Mask (a must) $5 at home depot
