Hi all, I've never been happy with the quality of the audio system in my Yeti Greenline, so after 16 months of ownership I finally decided to do something about it, and now I seem to have been bitten by the bug.   My first thoughts were just to replace the speakers in the front doors, but a lack of general information available had me being extra cautious about doing it, but finally got hold of a set of Pioneer TSA-172CI component speakers as a direct replacement for the standard fit speakers
