Smile easy and cheap 2013 jk sound system upgrade

like many others, i was less than thrilled with the sound of the "premium" sound system in my 2013 rubicon. i read all the posts about polyfil, dynamat, subwoofer amps, etc. i really didn't want the hassle of taking apart my dash to replace/dynamat the front speakers, or get into rewiring my sub or new amps.

i was looking for the easy and cheap upgrade. i tried the kicker soundbar upgrade, but didn't hear much of a difference. i neede somthing better.

after a bunch of searching i came across these on amazon:

Amazon.com : Jeep Wrangler JK Premium High Definition Sound Bar Speaker Upgrade Kit for 2007 to 2014 : Vehicle Speakers : Automotive

for $110 i decided to give them a try. wow- what a differnce! it sounded like i had replaced all 6 speakers. louder, better bass- big improvement.

next i spent $119 for these tweeters:

Quadratec Exclusive JK-TWEET11 - Super Tweeters (Pair) for 11-14 Jeep® Wrangler & Wrangler Unlimited JK - Quadratec

once installed i was blown away. now my system rocks!! my country western is lound and clear!! even with the top down.

my total investment is less that $250 and it took me about 45 minutes to do the simple install (both sets came with excellent, easy to follow instrutions- no splicing- just plug and play for both.)

i'm so pleased i had to share my experience. if, like me, you're lazy and cheap, but love good tunes (especially country), give this a try.

Thanks for the report. I was able to fix the tweeters with the cap mod and was looking for better sound bar speakers. It sounds like that's the way to go. I still don't know what to do about the two on the lower dash. They pop on some songs.

I dunno man. I'm picky about car stereos. I can't see being able to ever get this thing to 1/4 of where I would want it to be without spending 3000 bucks on it. So I'm not even going to attempt to mess with it.

None the less, these threads tempt me.

Personally I wouldn't waste my money on this. You can get way better quality speakers for the same amount or cheaper, and get some real dynamat or similar to treat the enclosure with and you will get way better results. I guess the tweeter would be worth it if you absolutely need something that's plug in play, but for $120 when you could get a decent set of components for ~150 makes no sense to me.

It's $3 to try the stock tweeter mod. You can read about it HERE. The premium tweeter isn't that bad, the crossover is...

The factory 6.5's aren't good and the Amazon replacement looks like a decent option. Unfortunately, they don't specify if they are 4 ohm or 2 ohm speakers. Our amp's are designed to drive a 2 ohm speaker and putting a 4 ohm speaker on them is like cutting the amp output in half. They say they are efficient, but also don't provide a specification.

I've been recommending the Infinity 6032si which is 2 ohms and 93db efficiency. They maximize amp output and are highly efficient (loud). There are 2 ohm JBL's as well that look to be excellent options.

I may give these a try, I have Pollyfield everything, with minimal improvement. Any recommendations on replacing the stock sub with another sub that would fit in the same enclosure?

To the OP, what did you use to replace the front speakers. Will these fit the fronts as well? Like to have all matching.

I installed the JBL P662s in my soundbar, stuffed it with polyfil, and stuffed the sub box with poly as well. The JBL's make a HUGE difference. I just bought another set of P662s for the dash and also the JBL P26T tweeters. Next up is a sub replacement in the factory enclosure.

once you get a sub, post it on here. I am trying to find a quality sub to fit in the factory enclosure for my 10th anniversary JK you, so far, I cannot find one that fits perfectly.

Based on recommendations from "Pressurized" I ordered a sub from Cadence so we'll see what comes of it. Rockford Fosgate also makes a shallow mount 2ohm DVC sub but I don't think it's as efficient as the Cadence. I installed the JBL tweeters yesterday and it completely transformed the system in my opinion. The range of sound and power handling really improved.

i spent a bunch on time researching replacement subs. with the 2 upgrades in place i'm really happy with the bass output- stock sub stays put.

Outstanding!!! I have not ordered mine yet, you are our guinea pig. I'm counting on the math working out for us.

I can't wait to hear your report!

Excited to hear a report on the Cadence. I've got it sitting on my watch list on Fleabay. Very tempted at $61 shipped to give it a shot after adding the Infinity's.

This ^

In a car you have a controlled environment with sound damping and such. Not in a Wrangler. You need a lot of power and speakers that can handle it. The speakers need to be installed in appropriate enclosures, not cheap plastic with no fill.

I assume the designers figured why try? It's already loud in there and we are gonna drive around with the top down. They cutoff the highs and lows and reduced power output so it's harder to break anything that warranty would have to replace.

While we are definitely not creating $3k systems with the work we are doing, we have made HUGE improvements in the system by changing out the speakers with the correct impedance and high efficiency and also doing the modification on the tweeter. The high freq. cutoff was done at the tweeter, making it easy to fix...

We are picking up big doses of efficiency which makes the system noticeably louder and the quality of the drivers is way better so they simply sound better even at lower levels. Remember 3db is equal to doubling the amplifier output and I'm comfortable stating that we are getting more than 3db increase from the sound bar replacements.

Who knows, it may not work for you, but it's a night and day difference for me.

I agree with Pressurized.....so far I've spent $4 on Polyfil, $65 on a set of JBL tweeters, and $80 for a set of JBL P662s for the sound bar. It make such a difference! Now, I spent another $80 on an additional set of JBL P662s for the dash and $62 for a Cadence sub that I haven't installed yet.

To put the tweeter install into perspective: With the stock speakers I could turn the volume up to "20" before it would start to really break up and sound bad. Now, with the JBL's I can turn it up to 26-28 and have really clear sound and tremendous clarity with volume. So for a total original outlay of $150 and now another $150 on parts that I haven't installed yet, I couldn't be happier with the sound.

Don't forget that as we age, our hearing is diminishing. Our ability to hear high frequency is fading and we need more clarity than volume. From what I've read, our hearing is at it's best at age 15 and degrades from there.

I have spent far more trying to fix the terrible headlights in my Jeep..........but that's another story.

Even cheaper was an old pillow (free), Infinity 6032si for the soundbar ($50), and a couple of capacitors for the tweeters ($5). My Rubi supposedly came with "premium" sound which I would rate a 4 on a scale of 1 to 10. Now, I rate it about an 8. Haven't done anything with the crappy front ones, but I don't think they are needed. Even with the top and doors off it sounds really good.

Our Jeeps really aren't good platforms for quality audio. But, simple, low cost upgrades that actually deliver real world improvements, that's something everyone can get behind.

Probably a stupid question, but do you stuff the sound bar through the opening when you replace the speaker? How dense should you pack it?

how long did it take you to get the sound bar speakers? I ordered the same ones from Amazon and they have shipped but the estimated time of arrival for is three weeks away.

I just checked newegg.com for the 6032si and they link you back to buying them from sonicelectronix anyway. If you are getting the 6032si, they will be 2 ohm at the voice coil. They call it "true" 4 ohm by adding the 2 ohm voice coil and the resistance in the speaker wire to show the amp a 4 ohm load...

Is it a direct plug and play with the factory system, or do you have to do some modifications to get it to fit correctly?

I also looked at the JBL's, they are about $30 more but have better reviews.

What exact cadence sub are you all talking about ? How much better would the jbls and the cadence sub be over a 2014 alpine premium ? Thanks

The Infinity 6032si comes with a mopar adapter bracket, you do need to provide 4 small screws and nuts to fasten them together. You also need the Metra wiring adapter to make it plug and play. It's still very easy to install these. The JBL's will need the mopar adapter and the wiring adapter to make them plug and play. The JBL P662s is pretty close in price to the Infinity's. Otherwise the "volume" performance should be similar, although they may sound different, and tonal quality can be somewhat personal.

The Amazon speakers that the OP used and Kickers are more plug and play, but they are 4 ohms. They should definitely sound better, but the math indicates that they will not be able to play as loud as the Infinity's. However, just due to higher efficiency, they will play louder than stock and sound much better.

I did a write up on the subs on my Stock Tweeter Mod thread. There you can see how to bring your tweeters to life, read more on the 6.5's and near the end is a discussion on the subs, including the Cadence. We have yet to get one installed to see if the math works... Right now we are waiting for KG32a to complete his install and give us a report.

Simple answer is yes, replacement of the 6.5's makes a big difference, modding the tweeters makes a big difference... and now we just need to know if we have found the right sub to make a big difference.

I have the "basic" non-premium sound system in my Jeep. Since it doesn't have a factory amp should I look for for a replacement speaker that is 2 ohm or 4 ohm?

Since I don't have the factory amp should I look to replace the stock head unit or wire in an aftermarket amp to get more power to the speakers?

If you zoom in on the pic of the speaker it is labeled .19 OHM so it should work with the 2 OHM amp we have. Nice find
