2007 Chevrolet Silverado 2500/3500 Class
I installed four speakers in a crew cab. With the adapter plates and wire plugs it was a snap. The bose paper cones were starting to tear, it was time to upgrade. I only used the front adapter plates. The rear speakers screwed directly in place of the old ones. It would only take about an hour to install the speakers but I lubed the window slides and door lock parts (once again it was time for some maintenance and the door panels were off). So far they sound great, not much for bass but with the old bose system I left the sub in place and that fills the void on the lower end.
Pros: Crutchfield complete hardware kit makes install easy, Great sound for the dollar,
Cons: none so far!!
