i found a great deal on the 4 channel R8.0:4 wich is rated at 75x4 at 4 ohms. and 250x2 4ohms. i'm thinking about picking up 2 of them. this amp would be great for my subs, and the infinity components i plan on purchasing. my question is does PG have a history of over rating their amps? i here people say bad things about them on these boards.
