I connected everything correctly, fuses still in tact.
I get voltage on both Positive Power AND Remote-turn-on when radio is on.
My amp light (Phoenix Gold) does not power on, and sub not working with it.

I also have voltage on the RCA inputs. Again, fuses look to be intact (not burned out).

WHAT Is going on???

Ground strong enough? Check the resistance of your ground wire to your positive wire. Should be less than 1 ohm.

Alpine,

think about what you wrote: "Check the resistance of your ground wire to your positive wire." I think you mean to the negative battery terminal.

dave,

to measure the resistance, you take a multimeter, set it on resistance, and read from amp ground to negative battery terminal. If your leads are not long enough, just use jumpers, then measure the resistance of them. Once you measure resistance of the ground using your jumper, subtract your jumper resistance.
