Subwoofer adapter ring for 2023+ Honda Civic Type R. Provides a tight seal when mounting aftermarket subwoofers to the stock sub enclosure and gives a little extra depth.

Mount to the box with the stock screws through the holes provided. Screw your sub in through solid parts of the ring once the ring is mounted.

Might want to flip the model before print so the deeper holes are on the bed.
