I successfully installed a RetroSound Model 2 radio in my '77, with 2 new Polk speakers also.  Everything appears to be working OK, except I am getting quite a bit of static when playing the radio, regardless of the station.  The sound is just fine when playing a song with an iPod.  I'm guessing that there is a problem with the antenna?  Perhaps a bad cable or some problem with the mount.  I have done nothing with the antenna.  The original radio did not work at all.  Any suggestions would be appreciated.

Is the "static" only with the engine running? And is the noise a whine or buzz like alternator noise, or is it more of a coarse type of noise that would be coming from the coil/dist/HT circuit? Check antenna plug behind the radio for proper ground/shield connection, and integrity all the way back to the ground plane like rraider said

The static noise is not a constant buzz, or hum.  It is more like random "crackling."
I will have to check the ground at the back mount of the antenna, I guess.  I'm pretty sure that there is no problem with the connection at the radio.  There could be some issues along the path of the antenna wire.  I'll have to trouble shoot that too.
