So I have a 2014 Silverado LT1, without the Bose system. It has the 4" non touch screen radio, and 6 non Bose speakers. I want to upgrade to the loudest, clearest sounding speakers possible. My local sound store told me Arc Audio was the way to go, and I was hoping some others may have installed some before I do. Looking for feedback and opinions, don't worry about price, I'm just looking for the loudest clearest sound I can get.
