Review on 🔌 VW/Audi Bose Integration Radio Wiring Harness 70-1787 for Metra (1993-2007) by Barry Shaker

I wasn't sure at this point if that meant I had an OEM subwoofer, but I was able to verify this when troubleshooting. This version of Symphony has a subwoofer, so I assumed I would follow the directions for "Amplified w/Bose". I actually did the opposite, following the no-amp instructions without using the RCA jacks on the new Pioneer head unit. I cut the green and purple RCA connectors from the wiring harness and connected them to the appropriate wires on the new wiring harness that came with the new head unit. Went like clockwork. How I actually felt doing wudu. I had no real confidence that what I was doing would work. I think I'm lucky.
