moble/base odd behavior in the car..

Is incorrect.

excellent and informative answer op: .... But would you care to elaborate on this? because it is contradictory to what I have been reading...

take an ohm meter connect it to negative and to the frame of the radio and report back if you get infant resistances

The frame and antenna connector is decupled with ceramic caps of varies points of the negative rail in side of the radio.. some how when I complete a circuit to the radio chassis to the negative power of the cars chassis. it is making the radio key off...
It is passing from the trunk lid mount of the antenna.

so you're saying your SO-239 does not look like this?

What, if anything, has been done to your two radios that make them different than the other radio that worked? Forget about that 'floating ground' thingy, that isn't going to be the problem. It's something that's different about both of your radios.

the 2 radios are from the 80's idk

it don't matter to be now as I think it is just the 2 radios and my friends don't do it.. we just swooped radios so all is good now...

?????

mine looks like that...
my antenna is the kind you drill a hole in to the roof or trunk lid non mag mount

If that is what your radio had, and it should be, than the chassis/frame of the radio, and the shield of the antenna, are joined electrically.

yes and because the antenna is connected to the body of the car the negative is passing down the coax...

same as the amp when it is plugged to the radio. it don't isolate the chassis/frame of the amp from the ground.
