Speaker Adapter and Rainshield
For Scion FR-S or Subaru BRZ front speakers, to fit Dayton RS180-4 speakers. This design also adds a rainshield.
It must be printed in 2 pieces, unless you have a large-format printer.
Mounting holes were made intentionally small, so drill them out to fit the desired fasteners (I used standard M6 nuts and bolts)
