Replacing soundbar speakers, polyfill, etc '12 JKU with pics

Hey all - there are several threads on soundbar speaker replacement already, but I wanted to post some step by step with pictures for those who havent done it yet. For those that haven't already done this simple mod, I will post my opinion and reviews at the end. In this case, I'm upgrading to the 6.5" Kickers from stock Infinity speakers, and filling the soundbar with polyfill.

To start, I used two 12x12 polyfill pillows that I got at a craft store (Michael's). I will say that these two pillows were exactly enough polyfill. I had a small handful left over. You need to get the polyfill up into the channel that runs to the dome light. This channel houses the speaker wire harness. For those with hardtops, it is not as wide as the area where the thumb-screws for the top fasten on. I was initially worried that if i filled that part of the soundbar with polyfill, it would get wound around the hardtop thumbscrews that pass through the soundbar. Rest assured, the channel is a seperate area of the soundbar. You will want to be careful as the soundbar plastic edges are extremely sharp. Gloves would have been a good idea, Ive got matching scrapes on my hands and forearm from trying to stuff the polyfill inside.

Use a 15T torx bit to undo the speaker cover screws (3) on each speaker. The speaker connection is a simple clip connector. Unclip and simply reverse process with new speakers. In this case, I used the (77Kick10) 6.5" Kicker speakers that fit with no modification and use the existing clip connector.

The polyfill:


Removed covers from Infinity speakers:


Back of Infinity speaker and connector:


Infinity speaker removed:


Polyfill inserted into soundbar channel and speaker hole:


Polyfill installed:


New kicker speaker:


Old Infinity speaker & Kicker side by side:


Installing Kicker:


The polyfill is packed in tight, but if you have worked with it before, it tries its best to escape because it is slippery and tends to expand after you pack it in tightly. So pack enough around the speaker, but dont overpack so it attempts to attack you as you screw the speaker in.

The results:

I love the upgrade and I can say honestly it made a HUGE difference in the acoustics inside my JKU. My hardtop is on, and has been on since taking delivery so I can only comment on the acoustics with the top on, but immediately you actually HEAR the soundbar speakers. For comparison, I left my EQ and audio settings the same (fade/balance) and left the same song queued up. Seriously, I smiled immediately when I heard the improvement

Forgive me if this is a dumb question, I saw you had Infinity speakers, does that mean you had the Infinity sound system in the Jeep?

Great post! Why did you chose the kickers over anything else?

Mainly because the Kickers are plug and play and fit the Chrysler connector with zero effort

Nope these I got from allusasupercenter. But they also have them on amazon. Model is 77kick10. They were $65 for the pair. Quadratec sells the JKKWR for $149 I think and I think they are marine rates, don't recall

I think the ones from Quadratec are weather resistant. I could be wrong though

As an FYI, I believe if you order replacement speakers from Crutchfield, they'll come with harness adapters that plug into the factory connectors and have terminals on the end to fit whatever speaker you buy, as well as install instructions..

I bought a couple cheap $1.99 pillows at Wally World for the fill and they've been sitting in my spare room for months now. Thanks for the write-up! I have some time off coming up very soon, so this should be on my short list of to-do's!

I did a similar mod on my sub and the speaker bar. However I used foam. I have Alpine OEM speakers and the sound is much better. I also have the headliner arriving tomorrow. The ploy fill / foam is an easy mod and well worth the short time and money.

I received my Kicker Speakers in the mail yesterday and will be installing them sometime this week (hopefully tonight). I put in my Hotheads headliner yesterday evening, so i can't wait to hear the improvement in sound once i get the soundbar speakers installed as well as replacing the subwoofer (which should be delivered 1 day this week as well).

I've got the Alpine upgrade...but pretty disappointed in it....and was thinking the headliner would be a big help. Is Mopar the only place to get it? Please provide us your findings on the sound improvement by adding it and the polyfil. Trying to decide if I need to buy speakers or not.

Thanks.

I purchased the headliner from hot heads. It looks nice but as far as the sound improvements, I haven't noticed anything. The foam I put inside the speaker bar and in the sub box made a big difference. I got mine at Hobby Lobby for about 6.99. Keep in mind I used foam not poly fill.

I did my soundbar ones last week with the Kicker speakers and the polyfill ($5 pillow from Target) - combined with the Mopar headliner kit it certainly sounds a lot better. I also have a pair to replace the fronts - but that's more work and will need some warmer weather to tackle that. I will eventually replace the sub with an Alpine Type R because it'll fit in the stock sub box (just need to get a small amp for it)

Is the infinity system amplified or does it just run off a stock head unit? This is a mod I plan on doing....I have the stockest of all stock sound systems and need a little more umph. I thought about running a small amplifier to the soundbar speakers. I believe Rockford Fosgate makes a plug and play system with amps for JKs.

Hey people,
Soo I didn't go with kicker and went with a pair of infinity reference for the soundbar and having a hell of a time trying to wrap my head around how to get these puppies in there. I bought some adapter brackets from Amazon that will require a slight mod to fit, which is fine, but I can't seem to figure out how the actual speaker will be secured to the bar...? Feeling confused...
Any help would be appreciated!

Mike

Are you asking how the speakers are secured to the speaker bar? If so... there are either 3 or 4 small screws around the outside of the speaker. Pretty easy to remove and replace

The Polyfill takes up most of the empty space in the sound bar and dash speaker boxes eliminating the echo and random, bouncing sound waves that cause poor audio performance. It turns an echo chamber into an "anechoic chamber". Essentially, think about an empty room in a house and how much it echoes with no furniture in there. Now, fill it up with furniture and the echo is drastically reduced because you've got sound absorbing characteristics in the room. Exact same idea. After Polyfilling my sound bar and dash boxes I actually have really good bass and my aftermarket Pioneers sound fantastic! Now as a result, I have so much bass, I have to figure out a way to keep my d@mn dome light from rattling!
