Review on πŸ”Œ VW/Audi Bose Integration Radio Wiring Harness 70-1787 for Metra (1993-2007) by Troy Rotermund

Revainrating 1 out of 5

Rear speakers still not working in Audi A4

Installed Android 8.0 head unit in my 2004 Audi A4 with its wiring harness to make sure the rear speakers are working. After installation, I found that the speakers in the rear doors still didn't work, but the subwoofer did work with the bookshelf amp, which uses the same amp as the rear speakers.

Pros
  • Durable test results
Cons
  • Can't remember
