I see that. I went with the bose on my 2014 Volt. I liked it a lot. But, then when buying my wife a 2014 volt, identical except for paint color and the lack of bose, I really didn't notice THAT much difference. Maybe it did have a little less bass...but I tweaked the bass up on the equalizer and it really isn't too far off.
I was just trying to see if someone thought the '17 Bolt sound was bad in the non-Bose model. I really would like to save some cash on this one as times are tight for doing anything with vehicles...one kid starts college this month. So the LT, if the sound were reasonable, may be the way to accomplish that. I'll miss the leather, and the bose, and the rear seat heat, but the rest I could really live without.
