Polyfil the sound bar?
 
whats involved?

Based on excellent information on this forum, I just ordered Polk DB651s and Alpine ktp-445u

Poly fill and a screwdriver :D

roadrat 09-07-2013 10:39 AM

how much is needed?

I ran Pollyfill in my Tj's sound bar and it made a difference. Not huge but took away the hollow/echoing.

I tried it, and the difference wasn't noticeable to me...

Use a medium amount and don't pack so much it touches the speakers. Its not going to be tremendous by itself and I personally wouldn't go through the hassle of front pods unless you're swapping speakers.

If you're swapping speakers though, I would absolutely do a little dynamatting and polyfil at the same time.

Dynamatting will cut down on plastic flexing and rattles. In a nutshell, air is gonna move. The less energy wasted flexing the plastic, the more comes out the speaker. Deadens resonance also. Polyfil tricks the sound waves into thinking the enclosure is slightly larger for more low end response. Will be most useful for sub's, marginal in little woofers, and useless in tweeters.

I have a writeup to mine linked in my signature thread.

I did it in my J/K and there is definitely less rattling or loose type sounds. Will you notice huge differences, its all in your ears. I would say mine is slight but noticeable. I do need to upgrade speakers but you cant run on speakers so I have to prioritize.

I used half a pillow. Pillows were cheaper than a bag of Polyfill. It made a huge difference. I had a reverb rattle before, now it sounds great! Even on my stock speakers.

Afmcronnie 09-08-2013 01:09 AM

I cut up an old pillow and stufed the bar in my 2012 JK, made a significant difference in the bass. I did the same thing in my 2013 JKU, it was the first mod. It helped the bass a LITTLE. Mostly it just moved the rattling from the speakers to the light pod.

MikeK46 09-08-2013 01:24 AM

Some say it makes a noticeable difference, others say it doesn't do anything. I'm leaning toward the notion that it's mostly placebo. Do it anyway, it's not expensive...what've you got to lose?

Beeg 09-08-2013 09:58 PM

I didn't notice any difference, but I may have stuffed too much in, I'm going to go back and remove some.

Afmcronnie 09-09-2013 06:46 AM

I think it makes more difference in the 2dr than in the 4dr. My 2dr responded well to this mod. Off the lot, my 4dr speakers had a very noticable rattle at high volume and bass settings. I stuffed the bar and the speakers quit rattling, but now the "dome" light has a pronounced buzz. After 4 Jeeps, Im used to crappy sound systems. Ill live with it. I just wish I could hear the thing on the highway with the top down.

Thorshammer7 09-19-2013 10:27 AM

I stuffed a whole 20 oz. bag in there and it completely eliminated all the buzzing and rattling. About $7 and 1/2 hour, time and money well spent.

Mclunk 09-19-2013 11:27 AM

I put about half a bag in mine, tons of rattle before, next to none now

MANGOJK15 09-19-2013 02:00 PM

Dynamat is a good option for the front speakers if you are looking to replace them. My audio shop used it on the front and polyfil on the soundbar when they installed my Alpine system and it sounds amazing.

I used a little more than 1/2 a pillow at about $3. My local target wanted $16 for the polyfill!

JKPaul 09-20-2013 09:43 AM

It helped on my 2 door.

It seems to have helped some people. However I couldn't tell a bit of difference in mine, but it doesn't take 5 minutes to do it.....So why not?

Thorshammer7 09-20-2013 10:26 AM

I stuffed about 80% of it inwards towards the light from both sides maybe no great improvement in sound quality but zero racket and buzzing. I faded all to the rear and couldn't make it buzz.

Mr.Dave 09-20-2013 11:06 AM

I agree with the comment about the two door being better than the 4 door. When it comes down to it, if you have the infinity system in a 4 door with the sub, you will not notice a difference. If you have a 4 door without the infinity, you will notice a slight difference. 2 door with infinity = slight, and 2 door without infinity = greatest improvement. I have a 4 door infinity, changed out the 4 speakers, and polyfilled the soundbar, front pods, and the sub, and not really a difference at all. When you look at it, the headunit in a non infinity system controls the output, so replacing that is your best bet for sound. In the infinity set up, the head unit goes to the amp (located under the steering wheel) and that regulates the wattage to the rears even more. Whatever you have read about replacing the wrangler amp with a nitro amp, don't listen, does nothing. Also, don't forget that if you have wiring for a hard top, and you have your soft top on, the plug that powers your rear wiper on the hard top lowers sound levels when disconnected. You can trick it by bridging two of the ports with a fuse. just search using a jumper jeep hardtop sound.

Why would you polyfill the sub? You have taken away all of the air space needed for the sealed sub enclosure...

You're missing the point of what polyfill does. Packing it so full it reduces rattles is NOT the job of polyfil. That's what dynamatting is used for. Medium loose packing with polyfil tricks the sound waves into thinking the enclosure is slightly bigger for better response.

Use the right tool for the job guys for best results.

Eliminate flexing and rattles? Use some dynamatting (or any sticky sound deadener strips) on the insides of the enclosures.

Slightly better response? Medium loose packing with polyfill, not touching the speaker.

At least this is my take on it over the years, but I'm not a pro so YMMV. Check my Sig link. There's a sub writeup I did in there when I changed my speakers. Good luck!

I had the same experience. It gets rid of the rattle. I had a horrible bass rattle with my stereo bass turned all of the way down. I stuffed the sound bar, and the rattle went away. Maybe some jeeps are more rattley to begin with than others?

MagicMtnDan 09-21-2013 01:44 AM

On a somewhat related note, could someone provide me a link to a DIY Infinity thread? I've not been able to find it/one. Thanks

Yup! The 4 doors rattle more, at least the 2 I tried out did. Dunno why, they just did.

I just think that stuffing it tight makes for a better speaker platform period.

stuff it tight. push in with screwdirver
