its because the trim cage is grounding out the hu.

It's actually probably grounding through the antenna.

Well here's one way to look at it but still different. All the old old houses never had a ground. Only 2 prongs not 3. But they found that was not safe so there is now a ground.

If that's wrong some1 please correct me.

I agree that this is more than likely the truth.

the cage would not ground it.

what kind of car do you have and what kind of radio is it??

probably uses a common ground

 

[302yota 10+ year member]

my radio is a jensen uv8 flip screen, already stated before.....and it must me my antenna because my radio won't even be in the dash and still work without the ground wire..

You still need a full current flow...that means from positive to negative. You can't have them both in one wire.

The 2 prongs were a positive and a negative

the 'ground' in your car is just a negative

Houses use AC...there is not positive or negative

There is a posi and neutral in a house.. lol

My moms house had a ground but the bare 4 wire (ground) ran under the house and was just hanging... I ended up driving a ground rod for her and hooking it up

theres a hot and a neutral but its not necessarily positive

I've seen some Sony's that will ONLY work if the ant is connected. Found that out when trying to bench test it. Power/ground connected and no go. Was like WTF.

Put it in the car and when I plugged in the ANT it worked //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

Most people look at me like //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif when I say hot... How would it not necessarily be positive?
