Best sound system upgrade for '12 JKU withOUT swapping unit.

Have seen scads of ambitious uber-mods to the sound system but here's one I didn't find covered with a quick site search:

If I want to keep the stock 430RN as-is, and don't want to run separate power, or drill, or get crazy with mods, what are the best drop-in swap-out upgrades for the Infinity sound system (with sub) in the '12 JKU?

(aside from poly-filling the soundbar)

Best, affordable easy speaker upgrades?

Replace stock soundbar and dash speakers with mopar kicker speakers and polyfil soundbar. Try these weird radio settings: bass +8, mid -3, treble +6

Funny, I'll have to check to be sure but I ended up with very similar EQ settings (if you can call it an EQ). The mid needs to be turned way down or it sounds super weird.

We need someone to try one of those add on systems like the Audiocontrol LC6i that sits between the existing head unit and then routes to an amp to power the speakers. We ought to be able to get so much better sound out of the overhead soeakers and the stock system limits them pretty severely.

Speakers made the biggest differance for me. I used Infinity Kappa 63.9i's in the sound bar and it made a world of differance. Enough that I plan on replacing the fronts as well.

You will get some improvement just swapping out the speakers in the sound bar, dash, and tweeters. However, you will not even come close to realizing the potential the new speakers will offer you unless you replace the head unit and the amp.

IMO, it's completely worth a $200-250 to swap out all the speakers and to poly-fil, which is all I've done so far. I initially wanted to avoid changing the head unit, but it's inevitable, I will be doing it because I want my speakers to perform as designed.

Good luck.

I have tried and am using the Audiocontrol LC6i. Works amazingly well. I have matched the output from the soundbar speakers to the fronts so I get a very nice equal sound all around. I would highly recommend it. I have written in other threads the other mods that I did along with this.

im just about ready to order my kicker setup, question is what kind of speakers are in the dash? i havent had it apart and was wondering if there just bass or are they 2 ways?

I was looking into the kicker component kit with the 1 inch tweeters "from what i read thats what fits in the stock pods" but it doesnt look like the dash speakers are 2 ways..
also what model number is everyone running for sound bars? looks like they have a couple options and i want to make sure i get the correct ones.

Did you use the sub with 2 ohm or 4 ohm voice coils?

Did you use the stock amp?? Does it also fit with no mods into the inclosure? Can you tell the difference?

I have the Audio Control LC6I with the base headunit. I do not recommend this set up. The LC6 introduces alot of white noise at low or no volume. I have been told that it works better with the higher end stock headunits. Speakers are Alpine R 6.5 components up front, Alpine R 6.5 2way in the soundbar and JL Audio stealth box for a sub. Power is an Alpine PDX5. I will be replacing the headunit as soon as I get a chance. If anybody wants to try the LC6I with sub control let me know.

No photos yet, will take some this weekend and post. Yes I do like it far better than the infinity ( I never had it but have listened to it ) The box fits great and is very well made. I would like to try it with more power to see if that might bring more life to it. The woofer has great fill with a good amount of impact.

I already questioned myself how to resolve the subwoofer placement. Especially if you do not have the 7-speaker infinity sound system (which you would not have bought if you planned on swapping it anyway).

The JL-box looks allright. Not as nice as the stock sub however. And I do not see it fit in a 2dr...?

I'd love to have a guide as to how all this stuff wires together. I'm looking at buying new dash and soundbar speakers, an lC6i and an Alpine MRX-F30 amp but really want to keep the stock head unit. I have been researching how to hook all this stuff together but have some questions so far.

1. did you run taps into the radio wiring harness for the leads to the speakers or did you tap into each speaker's wire for the LC6i?
2. How in the hell does the LC6i connect to the amp? Via two RCA cables, one for the front speakers and one for the soundbar speakers?
3. What kind of wire do you have to use for the remote turn on connection from the LC6i to the amp? Does one of those cables come in an amp wiring kit?

Anyone got a good diagram for me for this setup? I'd like to avoid paying these ridiculous DC area prices for having a shop do the work since I used to do all my own radio work 20+ years ago as a kid.

I've got a similar system in mine now.

Stock head unit (base, with Sirius) with 2 PAC SNI15 line converters (same purpose as the lc6i, just didn't see the advantage of the more expensive lc6i. Was debating 2 lc2's for the accubass or whatever they call it, but figured this would work about a well)

These are tapped into the speaker wires one for front and one for soundbar, and the resulting rca's are run to a jl xd700/5 amp under my drivers side seat that powers my front, soundbar, and sub

Today I replace the Infinity speakers in the sound bar with the Mopar Kicker 77KICK10 speakers. Cost: about $80.00 including shipping from Amazon.

That made a big and very noticeable difference to the stock Infinity system. The stock Infinity speakers in the sound bar were horrible.

I had already stuffed the sound bar with poly fill. I definitely recommend this mod. The speakers are totally plug and play. The project took about 10 minutes to complete.

I wish someone would make some measurements before and after replacing the rear speakers. Play the same song or better yet a test tone at the same volume number showing on the hard unit and see if there is any difference in SPL.

A home theater setup disc should work since these are DVD units after all.

I have a Sahara with infinity on the way. (Supposed to be coming in today) I have a few boxes of stereo stuff sitting at home waiting for the jeep to show up. One of the things in one of the boxes is a set of Polk mm651 speakers for the soundbar.

My new amps won't make it til Monday, and I still haven't decided on all my source changes yet, so my first step will be to install the Polks in the soundbar and measure them. I will measure stock as a baseline and see if I can post up. I probably will not put polyfill in at first as I'm going to rewire when I put in the happens, and would rather not have the poly in the way.

In case anyone is interested, I'm going with a pair of Polk PA D4000.4 amps and the following drivers setup active on the front

ScanSpeak Illuminator D3004/6620-00 Tweeter: Madisound Speaker Store
SEAS Excel W16NX-001 (E0049-04) 6" Magnesium Cone Woofer 4 ohm: Madisound Speaker Store

A polk audio mm1040 4ohm sub, which I will be building my own enclosure for in the rear.

The plan is to drive the fronts active two way off of one amp, bridge two channels for the sub, and drive the soundbar off the other two. I'm after sound quality not pressure so I'm hoping that pair of amps won't dim the crap off of my power system at my normal listening levels, but I'll change the battery if needed. I'm waiting to get the jeep to figure out the mounting for the new components.

I'm still looking at the source side but I have audio tool for android that I'm going to use for testing the system. Plan is to initially use aux in jack on the headunit for starting tests, and then connect the android directly to the amps, and try, so I should get a feel for how much eq / distortion the stock headunit is doing to the signal.

I'm very strongly leaning towards either a JBL MS-8 or audio control DQL-8 or DQXS before even buying a new headunit. (I have the basic RES130 knowing that I'm eventually going to put something else in) Any rate, I'm looking for better crossovers than what I have available in the polks, and I think that having multiple presets for the setup will be super cool as I can have me only settings for top up and top down, and then passenger settings figured out and stored, with the ability to switch easily. Plus I'm likely going to be hooking in speakers and amps before I get a new headunit and will likely need the line conversion. (Although I'm going to try first without by tapping in at the signals just before the infinity amp)

Oh yeah, and cost for all this, hmm. Well, my justification to the wife was that I can do a lot better than the 2k upgrade charge for the 720 on my own plus lockpik and backup cam that I want to add. Right now, I'm in $600 for the pair of amps and the sub. $131 for the MM651s (Which I suspect will end up only being active when I have the kids in the car) $1000 for the high end drivers for the front, so about 1700 so far.

Wish I knew how to install all this stuff to save money. The reputable install shop here in the Manassas area is ridiculously priced. You don't happen to live in the DC area do you!

LOL Yeah, I hear you on the install. Live in the Seattle area sorry. Actually, part of what I'm doing this for is the fun of it. This is going to be my first attempt at a serious car install and the time I already have in research into this project is probably already costing me way more than an install would. However, I have some experience with doing carbon fiber / fiberglass work, and I'm an electrical engineer by training plus I've done a few fabrication prodjects to a very anal degree that have turned out well.

Hooking up car stereo stuff electrically is actually quite easy. From there a lot of it is patience, trial and error, and playing with some basic measurement tools / software. That's really part of the attraction of the JBL MS-8. It does all the tuning / measuring for you in about 5 minutes!

I'll be living in nova soon. I am looking to upgrade my speaker system as well. when I do so, I'll take plenty of pics and show the installation. I haven't done one before but I like the feeling of DIY and learning about how to do things. going to upgrade the speaker system without having to get an amp, too. research still isn't done yet.

Well the speaker install is easy, it's the lc6i and amp install I am more interested in. I mean I kinda know how to do it but some of the wiring aspects I'm not sure of. I just don't want to pay a shop $400+ for 3 or 4 hours of work. I find those prices to be OUTrageous and won't pay them just out of principle.

Most ( Not All ) of the installs on here look like they were done my less than professional installers. Yes that shop in Manassas cost but you get a product with a warranty that you can be proud of. For some people time is worth more than a few bucks. Just my 2cents.
