11th Civic center speaker 3.5in adapter bracket

This bracket is designed for mounting a Hertz DCX87.3 speaker at a 45-degree angle, aligning the tweeter with the factory position in an 11th-gen (2022+) Civic. It allows for installation without any modification to the OEM parts. To prevent rattling, apply felt tape around the area where the original speaker meets the new one.
The bracket features 2.5mm mounting holes, compatible with the screws provided with the Hertz speaker.

The generic brackets should fit most 3.5" speakers without a spacer ring. There are options for mounting the speaker at a 45-degree angle using the second bracket, while the third bracket offers mounting holes at both 25 and 35 degrees. The mounting holes are 2mm wide and can be drilled to size if necessary.
