Popping noise from speakers when brakes are applied

[Sretenjovanovic]

As the title says i have popping noise from speakers when brakes are applied. I checked whole installation but everything seams fine. What makes that irritating sound?

Loose connection somewhere. Double check all of your sub wires / speaker wires both going into the speaker and out of the head unit / amp

Then check your power and ground connections

Also check your RCAs if you use them

^^^^^this

But also check fuse holder connections they are notorious for loose or bad connections. Look to make sure everything at the fuse holder connections are all flat and tight, i've seen them be really tight just not completely flat and that will cause problems.

I double checked everything, everything works fine, even at max volume. The pop sound is present also when I put in reverse when the engine is running. Do you think that light relay may cause this?

I've actually been having a similar problem that was getting worse and worse. It started out as a whining noise that went up in pitch with the RPM of the engine. It would get really bad sometimes and I could feel it from my subs. I've narrowed the source of the problem to the head unit, as the noise varies depending on the source (CD, Aux, USB, Radio). I pulled it out of the dash to check my connections and it got much better, like it was before with just a subtle whine. I still haven't figured out exactly what it was, but at its worst, I could tap my brake and make the speakers pop, too.

this, the infamous pico fuse

also, are you running them off the h/u? or off an amp? change your ground, or if your using your h/u ground your h/u with a star washer and a self tapping screw insted of just hooking it up to the wiring harness

Try grounding the outer ring of your rca's to the chassis of your h/u this usually corrects the issue

It's a fuse?

I'm running everything off a dual amp setup. I checked my ground and it SEEMED fine...but I could try a different location just to see if there's a change. My head unit ground is hooked up to the wiring harness, but the connection is pretty solid...of course I don't know what ground the factory harness has. I'll check it out. Thanks for the suggestion.

I know this probably sounds stupid, but how to you ground the RCA's?
