Car stereo only works when touching ignition wires and battery wires?

Question

I recently wired a new after-market stereo and it powers up when I turn the key but then immediately shuts off. The only way to keep it on is to touch the sets of ignition wires (red) to the battery wires (yellow). What am I doing wrong or is it alright to keep it this way?

Answer 1

you have a bad fuse in the vehicle   or this is a GM CHEVY vehicle from 2000 or newer
