I have never heard a dual headunit, but I'm partial to pioneer. The 6000 that I have wasn't that much more. I have always liked all of their eq adjustments. Actually they are the same price right now! I'd get the poineer6000ub. Once you get used to the controls, you shouldn't be disappointed. And yes the wiring harness has the two wires backwards. the poineer also has a usb, but comes from the rear of the reciever. Good luck with whatever one you get. chris
