Aluminum Door Speaker Adapter Plates (ND Miata)

These laser-cut aluminum adapter plates fit into the factory door speaker location on ND Miatas (2016-up).  They are part of our BOSE door speaker upgrade kit, but can be used with other speakers as well.  A different hole pattern may need to be drilled for anything other than the CDT woofers they were designed for.  The speaker cutout diameter is 5-13/16" (~147mm).
