Might be a stupid question but, will this work for a TJ sound bar too?

I did mine and it did nothing to improve the quality of sound. Added new speakers thinking it was the speaker with no difference with or without the poly fill. Not sure why the poly has no effect on mine listening to this thread. My front speakers work great with no mods. The rear still are anemic even with upgraded speakers.

The head unit and amp are limiting the rear speakers, which is why they still sound crappy. The poly fill will help cut down on the muddy mid bass but it can't get full range sound since the speakers are not being fed full range sound to begin with.

As far as this working on other vehicles, it should help just about anything that has a speaker in an enclosure, if there is no insulation in there from the factory.

Don't have a stock Head Unit, replaced it two days after getting my Jeep. I have terrific sound up front. Agree that stock head unit did no better but no longer have the stock unit and rear speakers were replace two days ago with new Kenwoods

May have been answered previously, (sorry) but how do you access the front dash speakers in a 2007 JKU?

Do the grills pop off using the allen wrench method? or does one have to totally dissect the dash?

Go to the quadratec site and search for the kicker replacement speakers. Download the installation instruction and it will show you step by step.

I picked up 2 standard size pillows from Wal-Mart yesterday and they were $1.95 a piece.

I did this last night and I have to say WOW!! I listen to about 85% Rap/Hip Hop and then the rest is Classic Rock/Hard Rock/Southern Rock/Heavy Metal. After I did this last night I went for a ride to see how it sounded. I keep my phone and sunglasses in that little space above the radio, and while sitting at a stop light with some Rap playing my phone and sunglasses were shaking around!!

Then I put on a song by Pantera called Broken that has dual bass drums, and I could feel it shaking my hat every time the drums went off!!

Best $12 I have ever spent!! $4 on the pillows and $8 on a six-pack!!

Curious.........

....has anyone tried using expanding insulation foam to fill the sound bar? I know some audio geeks use expanding foam for certain projects. Since the sound bar is hard plastic, it shouldn't warp and become distorded in shape. I guess it would find every avenue of escape if there are any.

Thoughts?

Thanx

Besides finding every avenue of escape, I believe it can warp the plastic if you fill it past the full when finished expanding point. That point is usually well well well before it is visually full. Add to those two the potential problems with wiring, electrical connections and annoying squeaks plus the fact that the expanding foam method is not nearly as easily reversible as the poly-fill method, I would not use expanding foam.

So al you do is
1) remove the speaker
2) stuff towards dome light
3) reattach the speaker

Few questions
-how far towards the light do you stuff it?
-how firm do you stuff it?

Stuff it toward the light as far as your hand can reach. Semi firm with no gaps.

Subs are either Sealed boxes: For deep, precise bass (which are ours)

Ported boxes: For forceful bass...moving the air

Since I have added an amp, I am actually thinking of adding the pods and filling it really tight around light area now. I will see how this works.
I stuffed the soundbar and my polks in the dash....huge difference. I just grabbed an old pillow and 1 is all it took. The sound is more pure and the bass is deeper

I added pillow stuffing to the sound bar last weekend and haven't noticed any particular difference. However, I feel better knowing I've done what I can to improve the sound.

Stuffing the sound bar today, hopefully it helps improve the sound till I can replace the speakers and amp. I have the infinity sound system and one little trick I read online that I just did was switch the wires to the sub. It actually has some bass to it now. =D

My 2012 JK was delivered yesterday and I swapped out all four stock speakers with Polk Audio. The sound bar Poly-fil was a no-brainer. It makes complete sense and everyone really should do it.

In reference to stuffing the front speaker enclosures... It will remove the bass from your system. Not a matter of opinion. It is absolute fact. What you are left with is a really crisp and accurate sound. It's enjoyable in fact. BUT (giant BUT here) you will find yourself immediately craving a sub for your system. If you want to jam jazz (and I do from time to time,) stuffing the front enclosures is a must. If you want some bass, you had better search the forum a bit and toy with ideas like creating baffles and cutting parts of the front enclosures out. Your bass response suffers dramatically if you simply stuff the front with Poly-fil
