Thanks guys. I originally planned to chain the amps together through the single sub out rca's, but i figured it would be less wear on the head unit if i split them up. But from what I am reading, it shouldn't be a big deal to have both amps ran from the same rca, so I'll go out today and do some re-configuring. I have all this in my 06 Dodge Ram 2500 Cummins Quad cab, and it slams. So if I get a little more sp from one of the subs, I should be able to aquire complete hearing loss even sooner!
