Subwoofer Mount Adapter Ring - 2008 Honda Civic Si

This is an adapter ring I designed and printed to fit a Kicker Comp C8 Subwoofer (PN 44CWCD84) into the OEM subwoofer location on my 2008 Honda Civic Si. This particular sub does require some cutting or bending of the metal within the trunk to clear the wire terminals on the sub, even though the magnet will fit within the opening with minimal cutting. This adapter allows the use of Socket Head Cap Screws (M5, IIRC) to fasten for the sub to the adapter, and then the OEM mounting bolts for the adapter to the vehicle chassis. I just ran the SHCS screws for the sub into the holes prior to fastening it together for real.
