Default Whining Noise Coming Through the Speakers

Alright, this gets a little involved, but i'll try and keep it simple.

I took a 10 disc cd changer from my mom'* van and installed in in the bonneville. Everything went great until I was about to hook up the antenna lead. Well it was bent at a 90 degree angle, but that wouldn't work with the input for the cd changer. So I tried my best to bend it straight without breaking it. Big mistake, so it snapped. I still get radio signals, but whenever I drive my car I receive a whining noise from the speakers. It is described as:

When my car is idle, it'* a slight gargling noise, a few pops and just plain sounding like interference. When I drive, specifically when I accelerate I get a high pitched whining noise that starts as soon as I accelerate and when I shift it gets softer, but again with the higher the rpms, the louder it gets. Also, when I'm running at highway speeds, the gargling has returned. I do not received this when the car is off and I'm just listening to the radio.

Now, the cd-changer has been disconnected (drawing too much power from my alt) in hopes that it would fix it. Well I looked at it today (when I disconnected it), and the lead was even worse, almost coming apart. I can see the copper wires for insulation. So I tried to put electrical tape around it to help, but no good. I'm pretty sure that i'm picking up interference from my alternator (it seems to be randomly overcharging my battery, between 14 and 16 volts) or just getting interference somewhere.

Any suggetions? I'm thinking i'm going to have to replaced the entire cable, anyone done this? Suggestions? Prices? Any help guys would be greatly appreciated.

You need to buy a GM Antenna adapter. The "bent" antenna lead is common in many GM cars. Try Wal-Mart or AutoZone.

and that will stop the whining noise? Even if the bent antenna lead is almost completely off?

the problem is still there. I took it to carx and they tested the alternator and they said it was good. The noise only comes through the speakers when the radio is on (when driving), if the radio is off, the noise goes away. Bad radio? Replace the antenna lead?

it'* similar to that, I got mine at advanced auto parts that connects from the gm standard to the universal, and then from the universal to the gm standard... I did this so that I could kinda replace the non 90 degree antenna lead with a 90 degree antenna lead. What about this cut and screw on kind? Where do I get this, and do you think it will be of some help?
