I was removing my 4 channel alpine amp out of my car and when i put everything back together I started having these issues. List of issues below.

1. car wont lock, unlock, trunk won't unlock with key fob or inside the car.
2. When turning the ignition to the first turn, nothing comes on. i mean nothing..can't lock, roll down windows etc.
3. when I turn the ignition to the next position, everything works. windows, trunk, locks.

I've checked the fuses on the passenger, driver side and under the hood. all the fuses are good. I have a bad feeling i fried something. Another thing i knew i should've done but didnt do, i didn't unplug my battery

 

Check all ground connections, especially the ones you touched, Make sure when you removed the amp, you screw back tight the factory grounding points.
