I couldn't find a good speaker adapter for my '03 Audi A4 so I designed one based on the OEM speaker. The model has a hole for Metra 72-9002 speaker harness adapter to slide into and 2 zip tie slots for cable management. 

There are 3 versions with different speaker mounting options:

  • M4 heat set inserts - 6.3 x 5.5 tapered holes
  • M3 heat set inserts - 4.6 x 4 tapered holes
  • straight 3mm holes for standard mounting screws

There's also a gasket model to print in a flex material to eliminate any vibrations. 

According to ECS Tuning this should fit the B6 (2000-2004) A4/S4, the B7 (2004-2008) A4/S4/RS4 and 8P (2003-2013) A3. 

 

Changelog: 
  •  8/13/23: Increased the diameter of the speaker mounting holes from 155mm to 157mm.
