noise while listening to radio

[wfo_18]

I noticed after I installed my SC that I hear a little noise while listening to the radio. The noise does not increase with throttle position and gets a little better as the car is warmed up. The same noise was present with the OEM head unit and the new one. While watching a DVD or listening to Pandora or CD everything is perfect. The BOSE speaker units were re-furbished by BOSE 9 years ago.

Any suggestions

I am sure I am not the only one out there.

One of bose amp is bad or going bad mine had a ticking sound. It's time for a rebuild or completely eliminate your bose amp and bypass it by running the wire directly from your head unit to the speaker.

Did you use engine management or upgrade the fuel pump?

It's called Dubstep; this horrible music kids these days are listening to... Try changing the radio station to something else more palatable.

You need to describe the noise more.

If it's a tick-tick-tick that goes faster and slower with the engine speed, then it's coming from EMI/arcing somewhere in the engine.

If it's a crackle unrelated to the engine speed, then it's more likely in the amps (which after 9 years really don't owe you anything).

But you said it's only with the radio, not other sources, which makes me think it's EMI. The main causes are: coil problems (there's a TSB about this), antenna grounding problems (also a TSB), or wrong spark plugs (I had this problem; the guy who did my 90K put in standard plugs to save a few bucks instead of the OEM resistor plugs).

Here's another clue: does your garage door opener work less reliably since the problem showed up? If so, it's definitely and EMI problem, most likely the plugs.

I will have to double check but when I installed the SC I did change the plugs out. I am pretty sure they are not the same plug # as OEM.

Correct the sound is only present on the radio but sounds perfect on all other modes. So I do not think that it is the amps within the BOSE.
