THANK YOU ALL FOR YOUR HELP!
but I think the problem was solved this morning.
The fact that the one tweeter still made noise when it was basically isolated bothered me....and that people had said to check for kinks and what not also made me think the tweeter itself might be the problem.
Also when connecting that specific tweeter to the outputs on the amp and still getting noise, AS WELL as only holding ONE wire (of the +/-) to the outputs still got sound, made me think the tweeter was shorting somewhere.
So this morning I checked the rear left tweeter.
Lo and behold its wires were PINCHED by the seatbelt bolt, against the chassis. How it happened and I didnt notice is beyond me.
When I took the tweeter out I saw that the neg. wire was frayed down to a single copper thread. Which leads me to believe that had I just completely severed the wire I would have been much better off because the tweeter not working period would make me rewire it. Instead I had to go thru all this to find this out.
So anyway, I stripped the wires and reconnected them.
The noise has disappeared!
Thanks for all the help, and thank GOD its NOT my amp.
Though I still have some soft "static", like what you hear with "silence" only slightly louder....
