To Polyfill or not to Polyfill?

That is the question....what are your thoughts? Does it really make enough of a difference to mess with it?

Do it, pick up a pair of speakers from amazon ($25-30 for a pair) and use polyfill that you get from a fabric/craft store, no use in buying the expensive stuff. Easy to do and your ears will thank you

Dont expect any outstanding difference in sound, but you will notice clearer music when you have it louder. Is worth it for 5 bucks

It costs nothing but time and a couple of bucks. Do it. Just don't overstuff, and don't expect a drastic change.

Just do it! I did it to mine and I could tell a difference. It's not gonna blow you away with the difference but you'll notice it. I went to Wal-Mart and bought 2 pillows for about $7 and cut them open and used the filling in them.

I vote "for" as well. Sub and soundbar are easy enough. Fronts are a little of a PITA, so I also say to go ahead and swap in some decent speakers at the same time. You can get all 4 for $100 for some nicer ones. Go with the Polks or something.

I have a link to doing mine in my mod thread in sig.

Nice Saturday project.

I did it, change was small, but some change. I also did the sub.

After my daughters softball practice, top down only. Daughter goes to the parked jeep to put away her stuff, turns on the music in the jeep with a friend as I talked to parents about 40 yards away. She put the music loud and it sounded great.

When you polyfill, music will sound better outside, than when you are driving inside.

Just make sure you understand what polyfill actually does.

It is meant for the sub, but most of us are using polyfil as a very cheap substitute for dynamat.

When I stuffed my soundbar I didn't even end up using half a pillow. It was probably along the lines of a 1/4 of a pillow. More definitely isn't better in this scenario either.

Don't overdo it or underdo it. Just a "medium" packing and leave space around the drivers so they don't touch the fill.

Like Mark said, it's mainly for low end, making the enclosures seem slightly bigger to the speaker.

NOT an earth shattering difference, but I used a little dynamat to cut down vibrations and resonance in the plastic, some polyfill, and new speakers and the premium system is good enough for me.

Either way, won't make it worse and a fun little project.

I noticed nothing in the soundbar and have not ripped into the dash to do the fronts yet. However, if you have the sub it is WELL worth it. Completely removed the boominess from it allowing me to get a more proper balance of bass level without sounding muddy.

I plan on doing this as well in my 2012. The plastic sound bar feels so flimsy and weak unlike the thicker plastic VDP one I had in my YJ. I was thinking of maybe plasti-diping it or coating it in something to make it harder. I mean ice cube tray plastic seems harder than this. Has anyone else done something like this?

The most expensive part of this mod is the price of the T15 torx driver needed to remove the speakers if you don't already have one. I did it when I swapped out my soundbar speakers and while I found it to be a slightly better it's such a super easy mod that it's worth doing anyway.

A waste of time if you don't use dynamat on the enclosures too. Just my two cents

Definite must do. I used fill from a couch throw pillow we're tossing as it's no longer fluffy. The fill is denser, compressed compared to a new bag from a craft store (this probably helps IMO). Anyway, I did 1 speaker in the overhead sound bar and it took about 5 minutes. My wife came out and wanted to take the truck so I let her have it. I cranked up the radio a bit, sat in the middle of the back seat and I could CLEARLY hear the sound coming out of the one I filled, the other couldn't be discernibly heard. I'll be heading out to the driveway to do the other the second she gets home.

The polyfill (from an old pillow) stopped the sondbar speakers.from rattling. Now the light rattles. Sigh.... any ideas on how to fix THAT?

Amen! Poly fill is a wade. Use dynamat on the dash speakers at a minimum. Completely eliminates rattle, especially in the pedals. Made a world of difference redirecting the sound as it should. I bought this product cause it was cheaper, it works great!

Polyfill isn't a waste. It is just that 95% of people (yes, I made up that number) use it incorrectly....either for the wrong purpose, of they use the wrong amount.

I figure that for $5 its worth a shot to see what happens and if its not worth a damn then you have stored some pretty good tender for your next campfire.

Anyone take pics of the dynamat in these areas? Any tricks you can provide on the install? Where else is it worthwhile to apply dynamat? I was thinking the tailgate and rear tub rails to reduce the vibration when the top is off.

How much should I order?

Did not take pics, because it was hard to see in the speaker boxes. I used dynamat in the dash speaker boxes, and on the tailgate. For the tailgate, I cut a piece sized to match the smitty gear tailgate cover. Applied it, put the smitty gear on, then attached my sub to the rear tailgate. This was the first time I used dynamat, but quickly came to realize that it is hard to mess this up, especially for the dash speaker boxes. You can literally just chop pieces of it up and place until you are comfortable with the coverage. I ordered this and still have a couple of feet left:

Still contemplating doing the soundbar, but I think it will kill the treble and clarity that I need from those speakers. Regardless, all the rattle from my sound was gone once I did the dash speakers.
