I replaced the fuse (obviously) and used a battery tester to check the power and ground and it works

I then plugged it into the docking bay and checked it's connections and that worked.

I checked what I have leading to the ignition sensor and didn't get a current with the ignition on or off.. not sure if I should have

And I checked what I have leading to the amp remote and it did have a current... somewhat high it seemed. I think I may have the amp remote and ignition sensor wired into the wrong place. My old stereo never turned off when I turned off my ignition, so I think that wiring's been messed up for a while anyway.

Is this a possible cause of my problem? I'm gonna follow the wiring back from my amp and see where it leads... the guy who owned my car before me did a hack up job on the wiring, so it's tough to look around
