I have a 2021Sentra SV big screen no Bose. It’s not audible for me. I intend to use a 5.1300 and may opt for a custom enclosure. Audio Control has no one who carries their full line of gear, and certainly no local car radio place is adequate. I really don’t want to do the installation myself but don’t want to be Moke. The installation will likely require an upgrade to the factory charging system, but Mechman is only a 6 miles away. I’m to old to want to assume the installation position, and too deaf to live with the factory junk.
