I JUST PURCHASED A 89 SE WITH 117K 1 OWNER CAR IN EXCELLENT CONDITION BUT FOR SOME REASON WHEN I TURN THE RADIO ON I HEAR A LOUD SQUEAKY PITCHED NOISE....IT ALMOST SOUNDS AS IF SOMEONE IS PLAYING A TAPE AND HITTING THE FAST FORWARD BUTTON AT THE SAME TIME....I SUSPECT THAT IT IS JUST THAT THE FRONT SPEAKERS NEED TO BE REPLACED BUT I'M CONCERNED THAT ONCE I REPLACE THE FRONT SPEAKERS AND FACTORY RADIO WITH AN AFTERMARKET ONE THAT I MAY STILL GET THIS PROBLEM...ANY IDEAS?

 

aging bose system. replace headunit and speakers with aftermarket..problem gone. (usually)

CAPS LOCK..you know what that button is for?

 

thanx.....the caps lock is for all those who have difficulty reading the small type......

DO YOU KNOW SOMEWHERE WHERE I CAN GET A GREAT DEAL ON BMW CONVERSION LIGHTS?

 

Power Antenna problem, most likely.

 

Or amp dying in the HU... Transistors picking up white noise out of the air and from the engine.
