Kicker is the new one, and they picked it up to replace Rockford. So that was more of a sideways move than a step ahead. I don't forsee any real growth in their car audio, look at the newest stores they've opened - car audio is jammed in a back corner with nobody staffing it most of the time. Last time I was in a best buy (the newer one on West Hillsborough ave) I couldn't have bought car audio if i wanted to, because there was nobody working anywhere near that area.
They are hit and miss on installers for sure. There are some stores that have a few decent ones and other stores that have all morons. The issue is often there is nobody in a managerial position that knows anything about car audio, so there is no leadership. To me that's not an acceptable standard.
