Acclerating/Revving noises in the air vent?

[Hazza]

Just noticed this last night, when i turned off my music and drove.

When i pull off in 1st, theres no sound coming from the passenger side air vent, but when i move up to 2nd gear and begin to accelerate, i can hear a slight 'brooooooooooom' sound in what seems like its coming from the air vent.

It doesn't happen in any other gears.

I've checked my air vents but doesn't seem to be anything in them.

Any ideas?

Really annoying when i have my music down, i can hear it!! Want rid of it!

By the way, its only sometimes!

isn't it just the sound of your engine you can hear?

did you have the aircon on at the time, or were the fans off?

No-one is ever gunna have a solution for that without hearing/seeing what you mean. Very strange.

 

[Hazza]

I turned off all my fans etc off.

Not stereo related is it ? If you have a sub etc it could be the wiring to that ??

 

[Hazza]

I do have a sub, lemme check the wiring!... Thanks Cat.

 

[Hazza]

Check my speaker wires etc aswell, but still doing it !!

The bonnet release grommet hasn't come out has it? That usually lets quite a bit of noise into the cabin.

 

[Hazza]

I hope that hasn't come out! :S

No biggie just shove it back in again?

Just sounds like interference. Turn the CD player off completely.....

i had a sound like that before i think it was due to ground of amp not connecting right

Im having this problem! I had to remove the grommet to make way for some sub wiring. How can i rectify this problem? any fillers I can use? Cheers...

when you said you checked the wiring before what exactly did you look at?
take the amp fuse out or just disconnect it anywhere and see if the noise goes

 

[Hazza]

i checked the wires connected on the amp!

 

[cat171]

Only done half a job there Haz.

 

[Hazza]

Yeah i realised that! lol...

But, i drove the car today to work, and the sound is coming from in front of me now, sounds like the air vent by the bottom of the from windscreen! :S
