Disconnected ground wire from HU- still works... WTF???

Civic's don't have power antenna's, correct?
Been a while since I worked on one.

If you have no power antenna, the blue wire usually will lead to nothing on the factory harness side, and, if you're using the power antenna wire for a remote turn-on (which is ok), and you're getting a ground through the remote turn on, something is grounding out, somewhere.

so are u saying i should investigate the remote turn on wire? could there be a slight cut in the remote wire grounding it out?

Probably getting a ground through the rca's.

i still say that you are grounding it through mounting it in your dash, take it out of your dash leave everything else hooked up except the ground, and see what happens.

hu's are probably case grounded as well as remote grounded...
