Lately when driving with no volume on the radio. I hear a whistling or humming sound from my speakers when I accelerate. It I have done no electrical work on the car. I still have the factory radio. What causes this and how can I make it stop.
Thanks for your help

 

Do you have a cell phone? I am curious because if you get the cell phone too close to the radion you hear noises through the speakers. Not sure if this would be the cause but always possible.

its called road noise... check ur ground or have the person who installed it check the grounds for you... thats a 97% chance of it

 

Check the ground of the radio? It still is a factory radio. Yes usally one cell phone pluged into the lighter and the other in the cuop holder. I will see if this is the problem.

 

You know what is, i made this mistake once and never again, you are running your RCA cables on the same side as your Positive wire, you cannot run rca cables on the same side as your positive wire, make the rca's run on 1 side and the power cable on the other side of the car...If this is split, makesure you dont have your rca running over some power wire or something, you can always wrap the rca wire in one of those plastic wrappers for the wire

 

Hmm, I'm too lazy to look up the Service Manual upstairs, but does the Max have a radio-capacitor/condenser/radio-condenser (they call it so many things theses days) on the egi/injector subharness?

I know it's there to kill the radio noise from the injectors, and the noise gets higher as you accelerate (naturally, higher frequency).

Just a guess, I'm sure someone else knows

 

u gave some good advice about running the rca and power wire on diff side and i have heard this before but i installed my stereo before i heard of this and i dont hear any whistling noises from my speakers and i also have a tv hooked up right above my pioneer cd player so i donno i gues im lucky for the time being.........i hope i dont start to hear whistling noises

 

Guy alot of people know about the whistling of aftermarket setups due to running on the drivers side etc. But he did not install anything it is a stock radio. It does not sound like he made any changes at all.

Hmm what else could it be then... Is it always or certain areas? Maybe frequesncies are gettign messed up. Does it do it just on the radio or tape/cd also?
