Well, I regrounded EVERYTHING to clean metal. I wired the CB straight to the battery, hot wire to positive, ground wire to negative. I put the wires through the same grommet in the firewall as the 12v power wire going to the amp, is that bad?

I still have the whining noise... dont know where to start. (filter for the RCA possibly?)

When i key the mike for more than 3 seconds, the speakers start squealing again... (Bad antenna maybe? Bad Coax causing leaking signals?)

The only time I have the whining noise now is when i drive down the road with the stereo on either pause or on AUX with nothing plugged in... so basically when the stereo is on but on an "idle" type thing... or if the volume is very low

Any help is greatly appreciated.. next step I'm thinking an RCA in-line filter... and new Coax and CB Antenna (antenna is old)

Thanks!!
