I have "wind" type of noise, something like wind blowing you know...its there with car off and on.

I have the big 3 done, i am running rcas on one side and power on another, i grounded the amps at many locations (bare metal etc...) and also at the same spot but nope!

So i was wondering what it is? can it be because my alpine 240 amp (4chan) is being run bridged?

Wind? Are you sure it’s coming out of the speakers?
That’s very strange, if it was a humm or crackle maybe we could help.
Someone here may have come across this weird fault.

a fan in the amp? I know one of my fans was audible.

no its not a fan or wind from the outside...its hard to explain...i will post a audio clip tomorrow, if i can get the noise to record so its audible enough.

do you have a cross-over in ur car? cuz my dads truck had the same problem and i just lowered the gains on the x-over and the wind went down...

Yes i do, BUT i had this problem with back speakers when they were running off the same amp, now i have them amp connected to comps in the front and its the same thing...btw the back speakers were full range so no xover.

Is it grounding? or could it be the amp making noise since its bridged?

I had a listen to the clip, was it that sound that changes pitch? it does sound like wind also there is a lot of rumbling in the clip too.
I have had a similar noise it was because the cables where getting interference.
Are you running rca cables next to other cables e.g. rca with the amp power wire?

p.s. it maybe coming out of the cd player to check that if you have an mp3 player with a input (which some do, mine has) plug it into the rca out of the headunit and record that and see if its still there.

Is the gain on your amp set too high?
