Anyone had a problem with their radio getting interference from the engine rpms? Is this just noise on the power supply to my radio that is causing it? Happens with the cd player too so it can't be the antenna. Thanks.

 

Sounds like you either have a .poor ground connection causing a ground loop or a bad altenator diode.

 

I'm fairly competent with electronics. Where is the diode and is it easy to take out for testing? I'll check my battery ground for good contact. Any other hints?

 

The diodes are normally on the back of the alternator. It is really a job for a good generator shop.

 

Did you ever get an answer? I just had my stereo installed. Dynaudio's/Kenwood Exceleon/Jl Audio amps and sub and I can hear interference as well. Any suggestions? Thanks!

 

Do you guys have 300s or 330s?? You can easily add that info for us as a signature.

The radio on my 300 is great, no engine interference and I can get AM/FM futher than my other car's new radio and usually pretty clearly.

I am very happy with the radio but wish it were digitial AM ready! Anyone know if they are?

 

Derek, no offense taken, basic information at least is very useful, in this case unless I missed it one can't tell what car they have. Mine has gotten a bit out of control, ok, it started out as a parody of some of the pics, etc like you mentioned, then I realized I actually was reading the others with such information to see what they used as related to information in posts., and as a quick means of surveying products.
Give me credit for at least minimized the font! Few do that!
