Review on Pioneer TS A4670F 4 Way Coaxial Speaker by Julie Clark

Installed in 2001 GMC Sierra 1500. Easy installation. I had to get creative with the installation as the included mounting screws and hardware are a joke. Since this is an old truck I just screwed the speakers to the metal frame. But if you have a machine that you don't want to screw into, I would suggest finding better fasteners. The sound quality is MUCH better than the series, even without the subwoofer.
