About this part
Functional rear speaker adapter ring for the Audi A4 B5 (1994-2001). It adapts the stock rear speaker location and mounting holes to a standard 6.5-inch speaker; the source identifies Kicker 6.5-inch hole spacing, reports PLA test prints and vibration, and advises flipping the part upside down in the slicer to avoid supports. Verify speaker fit, depth, clearance, fastening, vibration isolation, and material suitability before use.
