FWIW dept. I have the upgraded radio (430N) and it normally sounds bland. With the top off the other day I turned the radio up louder than normal and it sounded much better. Decent bass and clean mids and highs. I think you have to drive the stock speakers. They don't perform well at low volume.

It's amazing what a little pillow stuffing can do.

^This. Which is what I have been saying forever (probably on another forum too). It's a SLIGHT improvement, and yes, to normal ears it will be an improvement.

Expecting a "world of difference" or a "night and day" change will only be setting yourself up for disappointment.

Mine sounds better after REMOVING the polyfill from the soundbar. Another useless mod IMHO.

Are there any pics or video of people stuffing the front speakers and sub? The sound bar seems easy, but I don't know where to stuff around the front and sub. Thx

The first JK I test drove sounded like crap, the stereo. However, my dune paint job must have some awesome acoustic properties. My stock stereo sounds pretty good. Not changing a thing till I blow a speaker.

I spent a couple of hours this weekend stuffing things with polyfill and installing 4 new kickers. I did a lot of listening, especially the front dash speakers, with the old and new speakers, both with and without poly fill. The sound boxes behind the front speakers may be tuned enclosures - or not - someone from Chrysler and/or Alpine would have to comment, but I would say either speaker moves a bit more air WITHOUT the poly fill. I elected to put the poly fill in as it seemed to me to be a bit "crisper" with it in.

I used a variety of tunes in my testing: I will go on from titanic, start me up from the Rolling Stones, I dreamed a dream by Susan Boyle, andBilly Jean by Michael Jackson to see how clear things were, before and after. Without an oscilloscope, it is hard to be sure, but to my old ear, there was a MARGINAL improvement with the new speakers and polyfill all around. I have my premium soft top on as well so my tests were based on that.

I used to do a LOT of car stereo work as a kid, so am constantly looking for easy ways to get speakers out of and into cars. The Kicker/Mopar instructions are way too complex - obviously written to take maximum labour hours. I would stop following them after you:

- remove the dash side panels
- remove the glove box
- pull the panel below the steering wheel (a quick pull from the top and its off)
- and remove the three lower 7mm black hex head screws on both sides

I found it easy to prop the dash out a bit with a wrench while working.

The most valuable tip I can give is to get a short #2 Phillips insert bit, put a thin piece of tape on it, and force it into a 1/4" ratchet drive box end wrench and use that to remove the 3 Phillips screws holding the front speakers. The tape keeps the bit in the wrench so you don't have to fumble with it in an already tight space.

Also, on the drivers side, if you squeeze the connectors on the back of the differential disconnect control box (likely just a black filler piece on non rubicon models) it will come right out giving you easy access to the top screw.

The kickers are a far better speaker than the "premium Alpine " crap my Rubicon arrived with, but are still a "made in china" speaker. I'd sure liked to have a set of the Polks on hand to try as well.

I would say these speakers really start to show their stuff at a volume setting of 20 or above, and my kids thought Billy Jean sounded just awesome after I was all done. They both play in concert bands and have way better ears than I do.

I can see where adding a line EQ to preserve the HU and running high power amps would likely increase the dynamics of this system, but at this point, it's now good enough for me as I can see running Amps, new wires, etc, etc., etc, etc. would be a LOT of work and money in what will still be a very sub optimal acoustic environment. I don't need to feel the bass rattling my spine, so this is as far as I'm going on this mod with the possible exception of a 2 ohm double voice coil subwoofer when I find the right bargain, but it's not on my must do list in the near future.

Key word in here is MARGINAL improvement. Frankly there's not enough real difference to justify the $250 the project cost. Thankfully I found the Kickers on a Jeep Store for a lot less than the $500 a pair three dealers quoted me.

$250 for the 4? Which ones did you use?

The problem is that the speakers are only part of the issue. The amp is anaemic and you'll struggle to realise the value of good speakers if your system is incapable of driving them. For that reason I'd strongly recommend you not change the sub unless you're going to amplify it, the difference or lack thereof will disappoint you more than this project did.

I got the Kickers everyone on here everyone talks about. They were only $150ish, but brown Santa charges $50 to ship, and then rapes us for another $40 to clear them into Canada. The Polyfill was about $10. That's how it came to $250.

I know all about the amp. By the time I put in a signal processor (no way I'm giving up all my hands free etc. with the 430n) and real amps, etc. I'd be into another $1500. Not prepared to do that.

People say a kicker subwoofer makes a difference, so if I get one here in Canada it won't be too costly to try it. But, like you say it's likely not worth it. I have considered running the sub wires into a SMALL amp I can hide inside the sub enclosure as there is power right there from the rear 12v plug. No way I'm eating up all that cargo space with a big subwoofer enclosure.

I never really thought about it. If I recall right, the speakers need a certain amount of volume behind them so they can move in and out without fighting air resistance. However, I know mufflers on cars use reflected sound to cancel out sound. So, if the sound waves are bouncing around the enclosure, it might cancel some of the sound. Stuffing the bar should allow the air to move but inhibit the echoed sound waves. Guess I'll have to try it. Thanks for the tip!

You can buy a big enough bag of clean pollyfill for $10 at wallmart to stuff all the speakers and subwoofer. You're correct on the physics above. I couldn't see any holes in the front speaker boxes, so I assumed they weren't tuned port enclosures (which let the air flow out) and decided to leave the Polly fill in everywhere. It seems crisper.

Driving it today, voices seem clearer (e.g. talk radio) and it seems to have more punch than it used to at highway volume, but the higher impedance (I think) of these kickers results in turning it up a notch or two on the volume bar. M
Sitting I the garage, engine off at volume >= 25 playing Billy Jean or Beat It, or something equally punchy and CLEAN makes my ears hurt.

I'm feeling not bad about my $250 upgrade investment, but still pissed that Chrysler has the nerve to charge over $1500 for a stereo option that I would suspect can be outperformed with a $500 HU/amp and speaker combo from Wallmart. From now on when it comes to factory car stereo, if it doesn't say BOSE or Monsoon on it, both of which are engineered to the specific model car acoustics before their brand gets used, I'll order bare minimum and upgrade afterwards.

In my humble opinion this mod requires not only Polyfil but Dynamat as well. The speaker enclosures are plastic if you do not wrap them in dynamat and then fill with the Polyfil I do not think you will get the best result.

Dynomat/Polyfil Amazon.com $81.17
Kicker speaker upgrade (4) Ebay $144.06

You're probably better off just dynamatting the Jeep properly anyway if you want better acoustics, but that means more $.

Why did you cover the outside of your speaker pod in Dynamat?

I did not get the results that others spoke of. My sound levels appear to have diminished. I'll be removing some of the polyfill to see if that helps. I did pack it in pretty tight.

Yeah, I think a lot of people mistakenly use polyfil as if it were dynamat or acouostic foam.

We all know plastic enclosures are not great for speakers to begin with, so everyone is looking to get rid of the hollow sound by stuffing the enclosures, but that isn't the purpose of polyfil.

So I'll say this again for those that don't understand.

Polyfill is used to make a speaker driver inside an enclosure operate as though it were in a slightly larger enclosure. This works by slowing down the rear wave of the speaker, which outputs in equal intensity as the forward wave.

Too much polyfil is far worse than too little.

You put too much in as you have found out. You don't want to stuff any enclosure with this stuff, just fill it.

Reading this post, I have to surmise in doing this to the sound bar, will eliminate the rattling noise I hear in mine now when I have a bit too much bass????

Possibly, but probably not. Likeliest cause of rattling in the soundbar when you turn it up is from the interior light.

I have the same issue. The light dome rattle every time the bass goes up. Need to take it back to the dealer to see, if they can do something about that damn light dome.

I haven't opened my light fitting up because thus far (knock on wood) I haven't had that issue, but I imagine that judicious use of duct tape would likely fix it. Remember your simple engineering guidelines:

What we did to mine. I think it came out good.
On the subject of the rattling soundbar, never had that problem. My soundbar is done the same as my speaker pods are and I have had it that way since I did the sub. So far Ive tried a sealed 12 box, ported 10 box, a double 12 ported box that took my whole back seat, not once did the sound bar rattle.

Me either. After several months, I removed it and was amazed how much better it sounded WITHOUT that stuff in there! :-)
