I need a sub box to fit ONE 12 inch audiobahn sub but all I can find are dual sub boxes. I cant find and i need to find one soon because i traded my old pos z28 for the sub along with an amp and some money so some help would be nice. It doesnt even need to be vehicle specific, as long as it fits without sliding around everywhere

 

Build one it'll take a couple hours, $20 sheet of MDF some screws, glue, circular saw and drill. be stronger and sound 100x better than a pre-built.

 

You could Always build a fiberglass one using your trunk as the template. I'm looking into doing this myself.
