I'm guessing I used too much polyfill as the soundbar now has a distinct vibration on all types of music and talk radio. Annoying to the point where I really don't want the radio on at all.
I really don't have much directly around the speakers but the loud vibration didn't start until after the stuffing so it must be related.

|Shep927||Picked up my white 2015 JKU Sahara last week. I have the 430N head unit with the Alpine 9 speaker setup. Just did the polyfill and can definitely tell the difference, though maybe not as much as the others. I have a tweeter and a midrange in my sound bar and the speaker enclosure on each side is walled off from the middle of the sound bar.|

Tough to get much bass out of a low to moderately powered 6.5" speaker.
Best to hope for is a pretty dramatic increase in clarity and a bit more volume. Several have installed the Infinity Ref 6032si with good results coupled with Pressurized's tweeter mod and now we are experimenting with the Sub driver. ALL with the goal of low-cost, low-effort performance increases.

Hey everyone - my first post here. This forum is a great resource!
Anyway, I did the Kickers and polyfill in the sound bar. Count me amongst the underwhelmed. I didn't have huge expectations but based on some of the comments here I expected to be impressed. I have a 2011 JKU "Mojave" edition, which has the stock non-Infinity system. Based on the magnet size of the stock drivers versus the Kickers I expected there to be better bass response, but there really wasn't. Well, it is slightly better, and there are definitely improved highs due to the tweeters.
I think I would have realized more benefit from upgrading the front speakers. There's almost too much high end now due to the tweeters in the soundbar Kickers and still not enough lows. I want to keep the factory head unit so I may look into a powered sub of some kind.
Oh well, it didn't hurt for the $65 I spent.

I did this today and while doing it I noticed some funky stuff with the wiring and ended up rewiring my entire system so I cant tell if was the poly or rewire. Though Im gu3essing it was mostly wtwhe rewire im sure the poly helps. Either way its a good mod for me and got me off my @$$ an'd got my steroids sounding great! It seems the PO buthered they sterio installation !wh,en he installee the head unit and kendwoods in the soundb!aer. I tested it with my, wifes memimn cd and it thumps now.
Sourry about all twhe spellong errors, Im slow Im trying to btype withy a brok h!and.

CLD tiles placed on the inside of the enclosure along with a layer of polyfil mat. MLV and CCF placed on the bottom of the outside of the enclosure. I replaced the white matting that is on the outside back of the stock enclosure with a layer of 3M Thinsulate.
I place a piece of MVL and CCF between the enclosure and the body (you can see it on the right of the picture) and a piece of CCF between the joints of the enclosure and the plastic trim panel for the roll bar (you can see it in the center of the photo)
No rattle and my sub hits pretty hard.
I went all out with my enclosure and soundbar but either way don’t stuff the @#$% out of your enclosure. It just needs a layer of polyfil.

Got the soundbar stuffed, especially deep (but loosely) into the cross member and into the corner areas, making sure to go very sparingly around the speaker itself. Could somebody show a pic of stuffing the subwoofer enclosure with polyfill?

Polyfil worked great for me, seemed to tighten up the bass and sharpen the mids.
Quick question: Has anyone ever tried simply porting the sound bar? Seems like this might also be a solution, assuming you can do the math associated with figuring out what size hole to cut, etc...
I'm curious to try, but would like to know if any other members tried this. Please feel free to direct me to another thread if one exists.

|imdkoz||Just competed the polyfill mod and doesn't sound too bad. Did it transform the stereo into a world class audio system - nope. Does it sound better than it did before the mod - yes. Not bad for $3 and 15 mins.|

So think of it like this the stock sub enclosure is .3 cubic feet so it'd need about a 1/3 of a pound at the higher end.
Here is a great link that provides information on what it should do and why
A technical understanding of Polyfill - Technical Info & How To's - SSA Car Audio Forum
There's also videos on youtube that show how to correctly place it within an enclosure.
That being said. Sound damping is the way to go when trying to get rid of vibrations. You can get a couple of sqft for about $10-15 shipped. Just stick it in there and it should take care of it. A couple of sheets of second skin will do far more to get rid of rattles and vibration than any amount of polyfill will.
If you want to isolate the speakers you can use some foam placed and glued between them. I really don't think there is need for it with the way the soundbar is setup. But I'll find out this June when I start my install. It's going to be a pretty ridiculous install, nothing too crazy but I'm going to attempt to do a SQ build using the factory headunit and factory locations.

|mhicanders||It seems to me that the point of stuffing the sound bar is to isolate the left/right speakers.. depending on the music.. you can end up with one speaker essentially damping the other speaker when they are in the same air space. Try to stuff the space where the dome light is.. I believe some have dropped the dome light and stuffed that empty space with low expanding spray foam.|
|04-08-2014 08:28 PM|
So, after doing what you did and over stuffing it, I removed some stuffing and made sure that it wasn't crowding the speaker. I had realized when I pulled the speaker out that all the stuffing was actually on top of the speaker.
Don't be afraid to under stuff.

Polyfilled sound bar?
So I read a few threads about taking the speakers out of the sound bar and stuffing the hollow portion with Polyfil. It's supposed to be a little trick to get better sound quality so I figured hey, why not? However, nobody specified exactly how much to stuff in there.. I tried it yesterday and I can't really say I hear much of a difference. In fact, when I isolated the audio to the sound bar, it sounds kinda muffled. Perhaps I stuffed too much in there.(that's what she said) Has anyone else done this mod? If so can someone recommend a better technique for getting it to sound more crisp.

|Flashgordo||I put some poly fill in behind my sub and sound bar speakers today. Didn't notice any change when I sat in the drivers seat. Going to remove some poly from behind the speakers tomorrow like TexMedic suggested, and see how or if it changes anything.|

|tomgillotti||Thanks for the feedback. I'll mess with it more this weekend.|
|04-03-2014 11:33 PM|
Also, when stuffing polyfill people tend to go overboard and really pack it in there. It should be fairly loose and the fibers should still be able move a little bit. If it's too tight it basically just decreases the effective volume of the enclosure and you could be bottoming out your speakers.
Try taking some out then seeing how it sounds.
When you do polyfill you should add some, see how it sounds, add a little more and keep doing that until you get the sound you want. Think of it kind of like adding seasoning to your food.
|04-03-2014 05:55 PM|
So, I'm noticing a "boing-ey" type sound coming from the speakers after the poly-fill. It happens with higher base songs....
Did I over fill the sound bar? Sub seems to sound good, but rear speakers not so much. I put the fill all the way around the speakers...
|04-02-2014 08:56 PM|
The soundbar is going to just be rear fill so midrange back there should be good. You don't want highs stabbing you in the ear being that they are that close and you aren't going to get much bass in a speaker that will fit in there. However, most "stereo guys" will probably tell you that speakers in the soundbar are worthless because you want your sound stage up front so just spend the extra money to get a great set of components up front and a nice sub in the back.
That being said, what you put in depends on what you want.
I'm going to take some vacation time this summer and install all the gear I've been collecting and I got components for up front and a pair of 2 ways for the sound bar.
I'm going to be using the 3sixty.3 but even if you use the built in crossovers in an amp or the passive crossovers attached to the speakers you can make some adjustments to the sound coming out of the soundbar speakers.
I guess to sum it up, keep components with separate tweeters up front and a 2 way or just a midrange in the sound bar.
Edit: And just to add to the polyfill discussion, that's not something that is typically just a situation where you stuff in as much as you can. Deadening will work better for reducing rattle and improving sound.
|04-02-2014 08:33 PM|
Posted same thing in other thread...
Poly-filled the sound bar and sub. Not sure I notice a difference, but I think there is one. I just took the hard top off this past weekend, so that doesn't make it easier to tell.
Either way, $5.98 spent in two pillows... it didn't make it worse as far as I can tell.
|04-01-2014 08:10 PM|
Just thinking out loud (I'm not an audiophile either), but would it make more sense to go with a two way up front since there are already tweeters in the front and maybe even a two way in the sound bar for a deeper sound (I could see three way making more sense for the sound bar though)...?
Really, I'm out of my league with this stuff though...
