Hey guys, I've been driving an FC3C for about a year and a half now. About a week ago, I noticed a loud buzzing/ringing sound while driving on the highway. I noticed that it would grow louder and louder the faster I was driving. On local roads, the sound is considerably more subdued. I feel like it's coming from behind my head. Any insight into this problem would be greatly appreciated since I don't know where to start. Thanks.


Also, the headrest speakers just recently stopped working altogether. I'm assuming that I have to dig into the electrical wiring, but does anyone know if there's a simple way to fix that? Thanks again.

 

Maybe the two are related. If your speakers are messed up, but still have some sort of power feeding them it could be electrical noise from your alternator. Does the sound get worse when you are sitting still and rev the motor? If it is motor speed dependant and not vehicle speed dependant than I would say it is electrical noise.

Check that out.

 

Or disconnect your headrest speaker and see if the noise goes away.

 

thanks guys Im gonna try playing around with the wires right now
