I took my trailblazer SS in to have the speakers replaced and a subwoofer installed. They didnt know how to make the onstar work and took much longer than they had quoted me originally. When I got my vehicle back the drivers door panel was loose so they had to pull it back in and apparently they had not clipped it in properly. I would never go to these guys again. I could have had someone on Division in their garage do a better job.
