Its heavy duty 1" High density MDF it probably weights 150 LB its insane but doesn't flex!

 

Hey Jamie, you ever done anything with fiberglass before? A friend of mine just built his own fiberglass enclosure for a Alpine Type R 10 and it sounds alright. Just wondering if you had ever considered doing that. I was gonna do one for 6 12's, and then cut it down to 4 12's, and then just did the box I have now. It was just to expensive for me to do that.

 

Glass is so nice! Best sounding boxes in my opinion out there.

On the floor of your truck mark out the area u want the floor of the box to be on and lay down THICK poly plastic then use straight resin and keep it in the shape then build from there. I love glass but its messy work!

 

We used aluminum foil instead of plastic. Alot cheaper and easier to get.
