I shaved my antenna and removed the antenna motor from the back. I also installed an aftermarket cd player up front. When I start up my car, I still hear a noise like the antenna is moving, but I know thats not possible. It happens everytime I start it too. Any suggestions?

 

lol, i bet you are hearing the fuel pump "priming"

 

i had the exact same problem... , i have a s2000 antenna and it still sounds like the antenna motor is still spinning.
