Hey guys, the z has a slight hissing noise when i am at a stoplight. Its very faint, and its from the rear of the car. It's almost as though the deck is on without volume, however, this is not the case (the hiss certain speakers make when you have volume turned to 0). While inside the car, i lifted up the cargo mat and its definately from the rear of the car?


IS this normal? Car is 100% stock

Thanks

 

I have that also sounds like air leak

 

fuel pump noise maybe?

 

BI have the exact same noise, stereo on or off doesn't matter. The car has to b on tho. If on acc it doesn't do it. I hear it louder with my rear floor gone. The fawk is it?

 

I've been searching through the forum and have the same issue. Obviously this is an old thread, but does anyone else have any insight?

 

^ Have you checked that its not an exhaust leak?

 

I have not really looked into it, but I was quick to call it electrical because it seems like a very consistent hiss. Exhaust could be a possibility, but since it doesn't respond to my actions, it appeared to be more likely stereo.
