I have a 94 firebird formula and I would like to build a custom box for my car. Any fellow member has instructions on how to create one? Providing pictures of your setup will be useful too. many thanks

Just so you know, it is not too difficult to make your own box for a sub in that cutaway on the driver's side. Just follow that same procedures, but be prepared to spend a lot of time making the box fit just right and still be big enough for specs. I did it so I didn't have to give up any storage (T-Tops) space...
