I have a 2004 with the mach system in it. Recently when i've been listening to the radio a really loud buzzing noise has been coming out the speakers. Its a constant noise in all of them and doesn't matter what volume the speakers are at. Also I noticed that when it happens the noise isn't as loud when the rpm's are higher. I've taken it three times to the dealership since it's under warranty and they're complete idiots and refuse to fix the problem. Any ideas of what the problem could be coming from?

 

I would guess the radio

 

engine interference noise... typically a poor ground

 

not sure how the engine "interfers" since it is the power source but nk.....

 

Do you get the noise when the engine is off and the key is just in the acc poistion?

 

yeah it still does it even when the engine is off

 

does it make more noise when there is more bass? sound like a blown speaker?
