Does anyone here around the San Diego area know how to build a sub enclosure for an Orion HCCA 12.2 to fit in our trunks? I need to build a new one, the one that I had was a prefab, worked for a little while, but I opened my trunk tonight and it was falling apart. The sub was destroying the box. Or if someone has a program to build a box let me know I can send you the info for the sub to input into the program. I just need a little bit of help here.
