I just installed a Rio Car in my 1999 Mustang Convertible with the Mach 460 System. I completely removed the old head unit and CD player. I bought the harness from Crutchfield and all seems well except two things.

1) Has anyone gotten the display to dim when the headlights are on? I have the wires connected, it does nothing.

2) With the volume up, and the gain controls adjusted properly, it doesn't seem like the stereo is that loud. Nothing compared to the stock system. Is this because of the Ford amplifier?

Thanks for any help.
