Sretenjovanovic Posted December 5, 2011 Report Share Posted December 5, 2011 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? Link to comment Share on other sites More sharing options...
SnowDrifter Posted December 5, 2011 Report Share Posted December 5, 2011 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 ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...

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. 145.9@40hz 145.3@34hz big 3 X2 group 34 Deka Group 31 All 0/1 awg jl meta wire Alpine CDA 7894 Orion HCCA D5000 2 AQ HDC312's Crunch gpv1100.2 (for 6.5"s only) AQ pro audio 6.5" - 3 sets AQ supertweeters - 2 sets 2000 Slamry Link to comment Share on other sites More sharing options...
Sretenjovanovic Posted December 5, 2011 Author Report Share Posted December 5, 2011 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? Link to comment Share on other sites More sharing options...
Dylank811 Posted December 5, 2011 Report Share Posted December 5, 2011 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. 2004 Ford Mustang GTPioneer DEH-P7200HD head unitMach 460 Factory System Cadence FXA1600.2 Cadence S2W10 Cadence 4 AWG wiring Ported box, 2 cubes, 32 hertz Link to comment Share on other sites More sharing options...

Freshman6969 Posted December 6, 2011 Report Share Posted December 6, 2011 Do you own a pioneer? 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 Legal TL scores145.6 on the dash sealed up in the low 40hz area with the port out145.5 on the dash sealed up @30hz with the port inless then 1k clamped on a 3.5k! Why would you EVER WANT flex?huh?...flex is what can make the lows lower and more air being pushed correct?

m&c caraudio Posted December 6, 2011 Report Share Posted December 6, 2011 Do you own a pioneer? If you're talking to me, yes. Try grounding the outer ring of your rca's to the chassis of your h/u this usually corrects the issue Link to comment Share on other sites More sharing options...

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.
