Hi guys since I discover this post I immediately wanted to throw away my dirty/space eating MDF sub enclosure and started making my own fiberglass enclosure. Today, it's almost finished so I decided to post my results and give a few hints I discovered along the way to save a few bucks and a bit of pain. Take notes that this is my first time ever doing fiberglass, and also
this is a 12" sub.
First off,
get a gallon fiberglass kit you will need at least 3/4 if not all of it. I started with a quart kit from Canadian Tire believing it would go a long way but I managed only one layer of fiberglass with it. Also, I found out that two layers of resin with cloth on the back and two more in the front was plenty strong for my enclosure. I've seen how to's saying you should put 5-7 layers all around but I didn't want to spend on another 60$ fiberglass kit, so I guess time will tell if my enclosure is to flimsy but I doubt it.
Next, I found aligning the sub ring was very difficult and I didn't have a hot glue gun to quickly fix it in place. I
use strings to hold it in place and then aligned the ring and the wood sticks. that helped a lot!
Then, don't forget to
seal your wiring sticking out of the enclosure with fiberglass or use some sort of connector for easy removal like I did. I used a 1/4 mono jack cheap and easy to install just drill the right size hole for the female connector.
Finally, I had no good fleece for the front part so I grabbed
an old t-shirt and it did the trick!
here is the almost finished product, just need to glue to carpet that I grabbed in the trunk of a car at scrap yard and put the rubber ring for the sub.
