2016+ Scion iM / Toyota Corolla iM General...
My attempt to do a fiberglass subwoofer box for my IM.
I wanted to try this to save most of the trunk space since is not much.
I built it for a 10" shallow subwoofer. It has only 4" of depths which is perfect. It took me a couple days to make it but it was my first time. It end it being perfect...
