If it's a fast "buzzing" that follows the engine speed, it's picking up the interference from the spark plugs. Think you can buy a suppressor that filters this out but not entirely sure.

You may need a better ground connection to the radio.

When you say a noise - you mean the usual radio play getting louder or something odd?

Like the guy said in the 2nd comment I have engine buzz in the speakers.

Should they not already be in the plug caps? I think you are correct but I have never seen/heard this in years on a car since crappy 80's Datsun's.

Yeah should be, but I couldn't think of why they wouldn't be absorbing this so thought I'd try to help by just giving a possible cause. I'm no expert unfortunately

So maybe I was not correct before. Here's the whole story. My factory radio gone.

• I changed it for a mini ampfiler :

• Got swich 12 from cigarett lighter.

And I use it with aux jack cabel with phone or bluetooth reciver . (When I give charge to the phone from the car the noise is more powerfull.)

My final plan will build in a nexus 7.
