Audi TT Mk1 Bose Stereo upgrade DIY guide. How to wire up Bose to Pioneer radio. No popping sounds!

What a better way to start the new year with an upgrade for theAudi TT from the Bose concert radio. This won’t be your average upgrade and install video as I detail all the parts I used as well as an in depth look at the wiring so you’re able to smoothly get your Bose system singing with an upgraded head unit. I went for the (famous) Pioneer DEH 80PRS so that I could have more adjustability in the future. So far I am LOVING the set up and it’s made the Bose speakers sound pretty decent. I mean the subwoofer doesn’t give earth shattering bass but it still gives depth to the music which makes both top down and up drivig a pleasure (I smell an upgrade coming!) There's a common issue with these that you can get a POP sound when turning the unit on and changing sources. The solution is ground loop isolators. I test the system with and without the ground loop isolators connected and you can defintiely hear the difference.
