    Default Need Assistance/Advice - Issue with Stereo in '03 Silverado


    Just bought my son a 2003 Silverado Extended Cab LS in beautiful condition. The only issue with the truck was the front speakers, which were "crackling," so I assumed they were bad. I just got done replacing both woofers, and to my surprise, the "crackling" sound remained. Out of curiosity, I played a CD, which sounded perfect. For some odd reason, on AM/FM radio, there's a "crackling" sound coming from the speakers. It's not a lack of signal or static, as the radio will seek to the local stations just fine.

    Any idea why the radio would "crackle" like this, yet sound perfect using the CD player? I assume that means it can't be the amplifier, or it would sound the same on all sources.

    Yeah. Maybe the antenna is shorting out somewhere?

    Is this like a faint crackle? Or is it even louder than the music?

    Thanks for everyone's help, but I was able to resolve the issue...I only had time to replace the driver side speaker the other day, and replaced the passenger side speaker this evening...After replacing both speakers, the system performance was completely restored, and I must say, it's not bad for a stock system, particularly when listening to CD's...

    I removed the fabric cover on the old woofers, and found the foam surround had completed disintegrated, leaving the cone floating with no support...What I believe happened was the voice coils on both speakers were grounded on the magnet, causing the entire system to "short out" in a sense...I now wonder what the condition of the rear door speakers is, even though they aren't exhibiting any issues at the moment...

    OK, for you inquisitive types , here's a picture of one of the woofers...Both were in the same condition...Notice that the foam surround deteriorated completely as is missing entirely...The foam surround is what stabilizes the drivers cone, and positions the voice coil in the magnet slot...Without the foam surround, the voice coils were grounded on the magnet, causing all sorts of havoc...

    For simplicity sake, I just bought the stock Delco speakers on eBay for $25 each, so it was just a matter of popping the old one out, and replacing it with the new one...If anyone has distortion, crackling, or other symptoms, I'll bet your woofers are shot like mine were...I was actually quite surprised at how good the system sounds on CD's, so I see no need to upgrade the speaker components...
