My sub box is flush with the floor of the trunk, with the driver (IDMAX12) firing upwards. I'm mounting the driver to the back of the baffle, and I want to put a cool grill over it to protect it from crap rolling around my trunk.

What I'm thinking is I want to make/buy a grill that has the same bolt pattern as the IDMAX, so I can bolt right through the baffle to it (the baffle will be changing from MDF to plexiglass as soon as we get my bud's CNC router working properly, and having the bolt-thru would be a big help for supporting the sub)

Does anyone have a suggestion for a cool grill I could modify to do this with? I have access to CNC equipment to make my own, but it would just involve a lot of design time to get the 3D files made up.
