Hi Kids,
My 1989 325ic radio crackles and pops (as loud as the music) and the sound has obvious distortion on my drive to work in the morning.
I listen SOLELY to a mp3 player running thru a cassette adapter. (but the crackling is still there on am/fm/weather)
After work driving home after the car has been sitting in the San Diego sun all day and car itself is hot . . No Crackling or distortion, plays loud and clear.
If it's been raining, or I just washed the car, forget it, the crackling and engine buzzing is way louder than any program material.
A few Facts that may or may not be helpful:
The antennae doesn't go up when I turn the radio on.
There are no blown fuses in the fuse box
Heater fan has no audible interference
The car spends the night in a nice dry single car garage.
There's no leaks or holes in the conversable top or trunk.
I'm assuming I have a ground problem or short somewhere that fixes itself when the car body has warmed up. Possibly in the trunk amp harness (I think there is a trunk amp, YES?)
TIA for any suggestion O
