Subwoofer Adapter
2004 Honda Civic
Dec 29, 2025
Description
Remixed to fit my Pioneer Subwoofer in my 9th Gen FB6 Civic Si Sedan. Will fit any 8th or 9th gen civic or accord with the factory 8in subwoofer and any standard 6 hole subwoofer. I designed it in Fusion360 but based the design off of the original. Had to elongate the mounting slots to fit the newer Civic but left them long enough so they should fit the 8th gen.

Standard FDM printing settings: - Layer height: 0.2mm - Infill: 70% - Supports: As needed
