Vibrating Sound Bar

My JK is less than a year old, and for the past month the speakers in the sound bar are vibrating, even when there's only a commercial on the radio. I know what deep bass does to speakers, but c'mon, the NEWS makes them vibrate?

try taking the cover off the speakers and tightening the screws... A stock system shouldn't cause the soundbar to vibrate. Now my aftermarket system would probably cause problems up there if I hadn't stuffed it full of polyfil...

Your sound bar structure could also be loose. I think you tighten it from above the rollbar -not sure though.

same thing here......I replace all my speakers with JL AUDIO C5 Evolution coax for thesound bar and the rattle sound is louder than the one with Infinity speakers......Even on a spoking channel on the radio........I did not use Polyfil....mabe the soundbar herself.....but the rattle comes from the speaker area......

This sound makes me crazy.......

are you sure the speakers aren't busted? one of mine started vibrating. It was definitely a busted speaker. I'm not even going to bother with the dealer. I'm shopping around for real speakers.

seriously, take the speaker out of the soundbar and look at it. it's the most pathetic speaker i've ever seen.

My 2013 Wrangler Sport S doesn't even have 500 miles on the odometer and my soundbar is vibrating in the same manner as described in this thread. It is extremely annoying and a huge disappointment, especially in a vehicle that otherwise is so nice! I literally just took the temporary tag off of it and put the permanent license plate on it yesterday!

Hopefully Chrysler is monitoring this tread. I would love to share observations about this issue and another vibration under the driver's side dashboard. I'm sure there has to be a focus group or human factors/customer satisfaction study for a product of this caliber.

I've waited many years to buy my first Jeep and hate that I'm experiencing this issue.

Again, I hope Chrysler sees this. For what a new Jeep costs, we deserve better!

No offense but Chrysler could give a crap if a speaker vibrates a sound bar. They can't even get the ticking problem right, nevermind a sound system issue.

I would look at the 3 screws that hold in the speaker covers to see if that is the culprit. The light cover rattles on mine but I have a completely different aftermarket system. But on mine the cover vibrates. Im going to tackle that next.

Tight screws and polyfill will solve the issues of the stock system.

Yeah, no offense taken, but I completely love my Wrangler other than for this issue! The engine/drive train, power, handling, ride and comfort is amazing! BUT ... then I turn on music and level of annoyance that the vibration causes destroys the entire experience. I get it that I can tamper with the screws, etc, but seriously??? My Jeep is brand-spanking new and clearly this is a consistent problem as reported by others.

I get the whole little guy versus the corporate indifference thing. I have worked in the big corporate environment from the consumer protection/legal point of view and believe me, if you get your message to the right people at the right level, it can lead to a better product.

Chrysler has weathered too many near-death experiences to mess around with creating sub-standard products. This is my first Chrysler product (I used to be a GM loyalist and I currently own three Mazda products in addition to my new Jeep). Chrysler has slowly won me over through continuous improvements and enhancements. Now that they have me in the driver seat, I'm sad that such an avoidable annoyance is causing immediate disappointment.

I also just got a brand new wrangler sport and it has a light rattle on the dash. I test drove a couple others at different dealers and they all had the same rattle! The one I ended up with is the least but I'll probably try to get in there myself and fix it one day. If anyone has already fixed this kind of rattle, please let me know where to look first. Sounds like its a standard rattle...

This morning my JK is at Duke's Car Stereo getting heated seats and a 2-way remote starter installed ... they are going to take a look at the speakers and see if it will vibrate for them [Murphy's Law says it won't :-( ] If they see that it's a broken speaker, my warranty should cover that, I'm guessing.

Same problem with my 2013 JKU, Sound bar vibrates and I only just passed 800 miles... Plan on doing the Kicker amp/speaker upgrade and fear it will only get worse. Will Polyfil fix it or with the Kicker would one recommend another solution? If Polyfil, is any brand better then another? I know they use it for different applications and some are marketed for speakers while others are not.

I bade the same thing in my 2012, wal mart poly big bag is about 8 $. It stopped the rattle and made the sound much better.! Just make sure you you get the fibers not matting.

I have the same issue on my 2013. I put in new kickers because I thought it was the speaker. That made it worse. I guess I'll try the polyfill too.

Yeah, I haven't got around to it yet. I'm just going to put thin strips of padded double sided tape on the inside edges.

Just turned 1K on mine and the sound bar vibrates like crazy. I'm going to tighten up and stuff everything this weekend. My 09 JKU never had the problem.

I really don't expect the soundbar speakers to have any bass/mid-bass so you could try capacitors to cross them over higher. Our 2012 (Infinity) does not have this issue, but my 2013 (Alpine) does. I might just rip it all out and use JL Audio.

Okay, I finally got around to looking at the rattle issue with the sound bar. The rattle was coming from the dome light and a little bit from the driver side speaker.

I removed the light cover. It pretty much just pulls off. The rattle happened even without the cover. I tightened the one screw but still had the rattle. Removed the screw and took off the entire light fixture. I stuffed a small amount of polyfill between the light fixture and the sound bar, reinstalled the one screw and replaced the light cover. No rattle!

I then removed the one speaker behind the driver side and stuff the entire sound bar with the polyfill all the way to the middle of the sound bar. I used a screw driver to push the fill in as far as I could. Reinstalled the speaker and the rattle was gone! The speaker also now sounds much better!

I just upgraded my speakers on my 2013 JK to Kickers and they sound pretty good. The OEM speakers are very cheap. Have a magnet the size of a quarter and a plastic frame. Made in China, of course. POS!

I have a JKU Freedom Edition

It has a sub in the back, but it is not Alpine or Infinity.

What I found through replacing my sound bar speakers is there is no bass sent to these speakers from my stock deck.

I put some nice 4-way Kenwoods in there and now I can hear the news on level 3 when driving 65. The vocal sound is so much clearer.

I won't be messing with anything else as I don't anticipate anything other than rattles if I go adding more bass to the system.

A little education on how to properly polyfill your soundbar so you don't have a crap sounding rear setup.....

1) Remove both speakers from the soundbar (unscrew the screws, and unclip the harnesses.)

2) Stick your hand into one of the holes and follow the soundbar tunnel towards the other speaker....you will feel the center section of the soundbar...a tight 3-4" tunnel.

3) Grab your polyfil a large fistful at a time, actually, two firstfulls, and stuff it AS DENSELY AS POSSIBLE towards the center of the soundbar tunnel. Take caution not to push it through the tunnel to the other side, but act like you are. You want to pack that polyfil in there like you are robbing a diamond vault and are stuffing your pockets. TIGHT! The point of this step is to ISOLATE the air utilized by the two speakers....you don't want the speakers to share airspace, so you are essentially trying to make the left and the right "airtight" (or as close to it) from each other. Be careful that you don't shove the speaker harness plug into the center of the tunnel, otherwise you will need to start all over. Make sure the speaker harnesses are dangling from their respective holes while you do this.

4) Once you stuffed from one side, do the same thing on the other...stuff as much as you can AS TIGHTLY as you can towards the center. Once you pack it in there as tightly as you can, you are done with this step.

5) Grab a fistful of polyfil, and stretch it out as much as you can to LOOSELY fill the speaker hole area. You want it as LOOSE as possible behind the speakers. Place inside cavity, repeat on the other side.

6) Reinstall/reconnect the speakers/grill.

7) Bask in the sunlight of your own magnificence.

Look up my thread "rattle in sound bar fix" 9 times out of 10 its the bigger bolts holding to whole sound bar to the upper metal frame piece. People have found bolts sitting on the floor from them vibrating loose. Two of mine were freely spinning.

1. Tighten the bolts
2. Use Polyfill
3. Buy dynamat or competitor and cut into pieces and stick inside bar, especially the thinner places. You don't need to cover everything, a little goes a long way. This package will do your front boxes and the sound bar. Dynamat 10425 18" x 32" x 0.067" Thick Self-Adhesive Sound Deadener with Xtreme Wedge Pack : Amazon.com : Automotive

Also check your fade and make sure the rear isn't getting a disproportionate amount compared to front.

Great info everyone. Don't forget to remove your dome light and put a little polyfill between the rear of the dome light and the plastic sound bar. It was the dome light itself that was rattling on mine.
