To replace speakers in Jeep TJ, you do not need any special tooling, especially when you want to swap standard-sized speakers. More will be required if you decide to enjoy sound coming out of round 5.25″ speakers.

  • screwdriver
  • hexagon key
  • new speakers
  • wire adaptors
  • metal front dash adaptor plate, or plastic box adaptor
  • polyester fiber stuffing
  • metal saw
  • anti-corrosion paint

Let’s start with these simple steps:

  • Unscrew speaker covers on both sides of the dash. Use the screwdriver and remove two screws on the driver and two on the passenger side.
  • Remove speaker covers by pulling them towards chairs.
  • Remove foam speaker gaskets.
  • Unscrew speaker plates with speakers by removing four screws on each side.
  • Disconnect factory wiring from the back of the speakers.
  • Screw new 4″ x6″ speakers to the speaker plates.
  • Depending on speaker type, at this point, you may need to add adaptor wires to the factory speaker wires.
  • Place speakers back to the locations in the dash.
  • Screw speaker plates back in their place, making sure they are not loose.
  • Mount back foam speaker gaskets on top of the speakers.
  • Place speaker covers in place and screw them, ensuring they sit solid.

These were necessary steps to replace factory speakers in Jeep Wrangler TJ with factory size speakers 4″ x6″.

For round speakers, we will need different dash speaker adaptors, which will be either flat metal sheets or formed plastic boxes. 

Although metal adaptors are more popular, they offer the only location for the bigger speakers, but do not surround magnets.

Plastic boxes, on the other hand, have closed-back, therefore work as proper speakers’ enclosures. If I was replacing speakers in Jeep TJ, I would definitely use the plastic adaptors and filled them with speaker foam fillers. This way, speakers will play much better than in the open air.

Below are additional steps we have to take when installing round 5.25″ speakers. In the original speakers’ location, there is not enough room for larger speakers. Therefore metal dash supports have to be cut, but this modification is well worth the time spent. 

Before installing speakers back, it is worth covering cut metal edges with rust preventative paint that is especially important if you live in the coastal areas or with lots of humidity.

  • When speakers are removed from the dashboard, cut metal supports inside using a metal saw
  • The next step is to place new speakers on the front dash speaker adapter plates or the plastic enclosures depending on which type of support you want to use. I recommend using plastic boxes and fill them with polyester fiber stuffing, and although plastic boxes are more expensive, speakers placed in them will play much better.
  • Place the speaker in the dash and connect to the factory wiring cube. For some speakers, you may need to add wire adaptors to allow the aftermarket speakers’ connection.
  • When wires connected, screw the speakers to the original locations in the dash, ensuring stable connection. 
  • Place foam gaskets on top of the speakers
  • Cover speakers with dash plastic covers and screw them back to the dash.

Our favorite pick for Jeep Wrangler TJ front dash speakers:

When choosing speakers for Wrangler TJ, we have to consider the technical parameters that will tell us more about design, power, or ability to produce certain sounds. Technical parameters are, however, not everything.

In the case of the car audio and especially speakers, it is worth listening to the speakers before purchasing because the speaker that sounds perfect to me can have something missing for you.  

I was lucky to listen to all 12 types of speakers below, and, with this experience, I was able to choose top picks, one for each design.

Let’s go through all of them in more detail:

Best in Standard Factory Size 4″ x6″ – Infinity Kappa 64cfx

When you want to use factory mounting, the absolute best you can find is the Infinity Kappa 64cfx. This 2-way system with separated tweeters offers the mind-blowing sound quality, even when compared to larger speakers.

Although I listened to all speakers only in the studio, if I were about to buy replacement speakers for Wrangler TJ today, Infinity Kappa 64cfx would be the only option.

With music experience from the studio that is much larger than any car, I can only imagine how astonishing music they produce in a small closed cabin. The sounds are so bright, and with outstanding dynamics, they can easily compete with larger speakers.

The incredible feature is the UniPivot tweeter design. It allows you to direct high sounds precisely towards the ears so that you can enjoy the excellent stereo effect, even with the speakers mounted in Jeep TJ face down in the dash. Also, tweeters have level control that can be adjusted to +3 dB. This, however, has to be done before locking speakers behind dash covers.

Powerful and short kicks are created by woofer cones made in Plus One+ technology, and that means cone size is extended to the edge of the speaker. Cone is also made from ultralight glass fiber, which provides speakers with an amazingly short response time.

Another great thing about Infinity Kappa 64cfx is its crossover, which can be adjusted and support an additional mid-range speaker without any sound loss. In effect, you can have a 3-way system in the car, offering an outstanding experience.

To enjoy all that these low impedance speakers can produce, they should be powered by an amplifier. Ideally, if the amp can provide 80W – 90W at 2 Ohm, this would be the best power for Infinity Kappa 64cfx speakers.

See below a few parameters that make these speakers absolute top choice, especially sensitivity that is unbeatable within this speaker size:

  • Lightweight Plus One glass fiber woofer cone rubber surround
  • Edge-driven, adjustable soft dome tweeter
  • Impedance – 2.5 Ohm
  • Power RMS – 60W (180W peak)
  • Frequency Response: 75-25,000 Hz
  • Sensitivity – 94 dB

The Best Round 5.25″ for Jeep TJ front dash – Focal ICU130

If you want to choose round speakers for your dash, you have to add a speaker adapter, because of different mounting holes. 

Again, I did not have a chance to listen to any of these speakers inside the car. However, I spent over four hours listening to them in the studio, trying to pick the best. Because I am a fan of rock and jazz, I was looking for a strong and clear mid-range with a perfect vocal that would be as good as live and unplugged music.

The best and most natural sounds I have found were made by Focal PC 130F, but I would not choose this one for Jeep Wrangler. Why? Because of the noise inside the car.

Focal PC 130F with their extended frequency response are the perfect speakers for a quiet environment in more luxury cars, but not for Wrangler where is much louder inside than in any sedan or SUV. They will play beautifully, but you will not hear everything they have to offer, especially with the roof down.

Instead, I would pick Focal ICU130 for Wrangler, and here is why.

They play similarly well to the higher PC130F but do not have the same extended frequency response, and you will not lose anything.

The frequency bottom at 90Hz is low enough for front dash speakers. Anything lower than that should be supported by bass speakers in the soundbar and subwoofers.

Speakers in front of us are not responsible for dynamic, but for stereo effect, and Focal ICU130 are perfect for that.

Their most significant advantage is adjustable tweeters that are made in inverted technology. By adjusting the little switch, you can make them play the highest tones louder by 3 dB, and this is a lot.

3 dB extra coming from front speakers means they play twice as loud as any other speakers powered by the same wattage. And this is on top of the already high sensitivity of 91.8 dB.

Having sensitivity 91.8 dB in 5.25″ speakers is incredible. Such high sensitivity is not achievable by many producers even in much larger 6.5″ speakers. With this sound quality, Focal ICU130, even with a price close to $200, is a bargain of the Century.

If I were about to buy 5.25″ speakers for Wrangler, especially with an open roof, Focal ICU130 would be ordered today without thinking twice about it.

Below are a few technical details to look at:

  • Woofer made of polyglass with butyl rubber surround
  • Aluminum/magnesium inverted dome tweeter
  • Adjustable horn design tweeters to +3 dB
  • Impedance – 4 Ohm
  • Power RMS – 60W (peak 120W)
  • Frequency Response – 90-21,000 Hz
  • Sensitivity – 91.8 dB

Review of oval 4″ x6″ speakers:

When you are on the budget or looking for other options, see below a few more speakers worth considering for the front dash in Jeep Wrangler TJ.

Hertz DCX 460.3

The Hertz DCX 460.3 speakers add that extra kick that was missing from the factory speakers. Thanks to its high power, excellent looking design, and clear sound quality, these aftermarket Hertz Dieci speakers deserve a place on the top list of the best 4″×6″ car speakers.

The Hertz speakers use a neodymium magnet, making the speakers lightweight but with impressive bass for their small size, starting at 65Hz. The clarity of the sound is out of the question with Hertz speakers as it is backed up by a great excursion and matched resonance.

The only weakness I notice is the sound of the mid-range and vocals that are not as bright and transparent when comparing to Infinity Kappa. dual instruments are not very satisfying.

The Hertz Dieci Series 4″ x6″ speakers are perfect for a system powered by a factory stereo set. With only 40 W RMS, they don’t need a large power station, yet they can produce intense highs.

The built-in crossover splits the low and high frequencies, transferring the lower frequencies to the treated paper woofer with a unique polyurethane surround, while the highs are directed to the PEI dome tweeter.

  • Impedance – 4 Ohm
  • Power – 40W RMS (80W peak)
  • Frequency Response – 65-21,000 Hz
  • Sensitivity – 93 dB

Rockford Fosgate T1462

Rockford Fosgate is known as a producer of speakers for real car audio enthusiasts. These 4 “x6” Power T1462 speakers use advanced design elements to ensure the perfect sound in your car for a long time.

The lightweight polypropylene cone is reinforced with durable carbon fiber, and it does not change its shape when you press hard on the speaker.

You will hear accurate low and mid sounds, that are supported by an aluminum dome tweeter. These speakers can handle up to 45W RMS so that the head unit can power them, but if you want to get the most out of them, you should connect them to the amplifier.

The patented VAST ™ technology is an excellent solution to increase the cone area within the same speaker size. The larger cone delivers deeper bass and more power than the average 4 “x6” speaker and is supported by a durable rubber suspension designed to last for a long time. 

T1462 speakers have more mounting holes than standard speakers to mount them in other than factory places. Although this is not the case in Jeep TJ, it can be a good option for different vehicles.

Although these speakers sound good, their downside is very low sensitivity, which means they need a lot of power to be able to play as loud as other speakers.

  • Power – 45W RMS (90W peak)
  • Frequency Response – 75-22,000 Hz
  • Sensitivity – 85.5 dB

Kicker 47KSC4604

KS series from Kicker offers a significant improvement to the factory speakers. The KSC4604 4″x6″ speakers have come made of polypropylene for natural sound with satisfying bass, and they sound good. Also, high tones, produced by a 1/2″ tweeter with a silk dome, make the vocal smooth without too much sharpness.

With the KS series, Kicker has created speakers that can produce significant volume even when powered by factory stereos, meaning you don’t need an amplifier to listen to quality music, and this is a big plus.

The KSC4604 are low-profile speakers, which means they have a reduced mounting depth. While not the most critical with a Jeep TJ, they are also an excellent option for other cars with significantly less space in the dashboard or doors.

  • Power – 75W RMS (150W peak)
  • Frequency Range – 50-20,000 Hz
  • Sensitivity – 88 dB
  • Impedance – 4 Ohm

Infinity Reference REF-6432cfx

Infinity’s Reference Series speakers remain popular and do not seem to be the old style. Classic REF-6432cfx 4″x6″ is no different and remains a popular choice for replacing factory speakers because of their competitive pricing and fantastic sound.

The Reference Series polypropylene woofer with its durable hi-roll rubber surround ensures you’ll enjoy powerful sound every mile you drive, even in a loud car, like Jeep Wrangler TJ with the roof down.

Its oversized cone moves more air than other speakers of similar size, adding plenty of punch to the speaker’s impressive performance.

Add to all that small textile dome tweeter for more precise and smoother highs that are hard to be confused with other speakers.

These lower impedance 3 Ohm speakers will show everything only when powered by an external amplifier, and even better if an amplifier will work with 2 Ohm.

Powering them from a factory head unit will still make reasonable sounds, but acoustic and depth will be missing. So, if you decide to install the classic Infinity Reference Series REF-6432cfx, make them work with an external amp. 

  • Power – 45W RMS (135W peak)
  • Frequency Response – 75-21,000 Hz
  • Sensitivity – 92 dB
  • Impedance – 3 Ohm

Kicker 46CSC464

Another Kicker, the little brother of KSC4604, is a good budget option for systems driven by factory stereos. 

Kicker’s 46CSC464 4″x6″ 2-way speaker serves up stellar sound using a polypropylene woofer for the upper bass and midrange, plus a PEI balanced dome tweeter for the highs.

You will get good results powering these speakers with a factory radio, but with an external amplifier, you will enjoy much better quality with more details.

  • Power – 50W RMS (150W peak)
  • Frequency Response – 50-20,000 Hz
  • Sensitivity – 88 dB

Review of round 5.25″ speakers for Wrangler TJ:

All speakers below are worth listening to, and although I have found the winner, your preferences in high tones, bass, or even music style may be different. 

When searching for speakers, do not start listening to these from the top shelf, unless you are ready to buy them immediately. 

Focal PC 130F

This is my favorite and absolute winner from 5.25″. But, as I mentioned earlier and this is my personal opinion, I would not install PC130F in Jeep TJ. Unless you listen to music in the garage in absolute silence, you will never be able to experience the full potential of these phenomenal speakers while driving Wrangler TJ.

Engineers from Focal made an outstanding job making this speaker with an ultra-lightweight fiberglass cone that offers exceptional audiophile experience. Every sound is so precise, and thanks to the inverted dome tweeters, high sounds going beyond any audible tones we can hear. 28.000 Hz on the top is a lot and without a single distortion. 

With 60W RMS, you can try powering them with the factory head unit, but to see their real potential, they should be connected to the amplifier. Ideally, around 90W RMS per channel and in A/B class. Do not use any mediocre amp, even when it is more powerful.

Focal PC130F is not about the loud; it is about sound perfection.

  • Ultralight glass-fiber cone with surround from butyl rubber
  • Aluminum tweeter in inverted dome technology
  • Impedance – 4 Ohm
  • Power – 60W RMS (120W peak)
  • Frequency Response – 75-28,000 Hz
  • Sensitivity – 90.5 dB

Polk Audio MM 522

MM 522 car speakers not only sound great. More importantly, these are marine speakers, which means they are suitable for any off-road and wet trips.

You will not risk any damage when they get splashed with water or mud, that can be very easy when driving TJ without the door.

Polk Audio MM522 speakers play very well with radio, but a lot better when powered by an external amplifier. They are designed to produce loud sounds in an open environment.

Their baskets are made of lightweight carbon that holds inside a titanium-coated polymer woofer cone and tweeter made of terylene fabric. 

Such a quality guarantees an outstanding experience, and I was stunned by how loud music they can play with their 90 dB sensitivity, without distorting any sounds.

  • Waterproof titanium coated polymer cone
  • Terylene fabric tweeter
  • Certified for marine use with waterproof surrounds
  • Epoxy coated crossovers
  • Power 80W RMS (240W peak)
  • Frequency Response – 50-40,000 Hz
  • Sensitivity – 92 dB

Kicker 47KSC504

Any speaker from the Kicker KS Series will make a massive improvement to the car audio quality, and the small KSC504 are no different.

They sound natural and play with impressive tones quality, thanks to polypropylene cone and silk dome tweeters. I have noted fantastic violin and guitar tones, with excellent and natural vocals.

Although according to Kicker, these speakers will play well without an amplifier, I was not listening to them when powered from the head unit, so it is hard to tell.

However, with power handling of 75W, there are not many (if any) factory radios that would power these speakers. I would not buy them without a supporting amplifier, especially by looking at a low frequency of 45dB.

They simply need a lot of power to produce nice bass, and mid-bass in drum kicks is really good.

  • Power – 75W RMS (150W peak)
  • Frequency Range – 45-21,000 Hz
  • Sensitivity – 90 dB
  • Impedance – 4 Ohm

Alpine SPE-5000

Alpine SPE-5000, like any other from the Type-E Series speakers, offers soft quality sound, and will not ruin your wallet. 

SPE-5000 speakers are not designed for hard, dynamic, or rock music because of the lack of low tones. But if you are a fan of smooth, jazz, or classic, these are speakers for your car, and you will not be disappointed.

Their cones made from mica-injected polypropylene make crystal clear sounds, and you do not need a lot of power to hear all produced sounds. 

SPE5000 are great speakers when you do not have an installed amplifier, and sill can deliver impressive performance. In my opinion, they offer the most sensitive yet precise sounds from all speakers in this review.

  • Power – 50W RMS (200W peak)
  • Frequency Response – 82-20,000 Hz
  • Sensitivity -87.5 dB
  • Impedance – 4 Ohm

JVC CS-DR521

CS-DR521 made by JVC is another excellent option for factory speakers replacement. They do not cost a fortune, so if you are on the budget, they are worth considering as new dash speakers in Jeep Wrangler TJ. Their design prevents them from overheating, which means if you drive with the roof down through the desert, or anywhere where it is sunny and hot, CS-DR521 is the right choice.

Like in other JVC speakers, the carbon cone produces constant and precise sounds, which thanks to the neodymium-magnet tweeters being extended to over 25.000 Hz.

CS-DR521 can make great sounds, regardless of the source of their power. They play equally well when powered by the amplifier as well as from the factory head unit.

  • Power – 40W RMS (260W peak)
  • Frequency Response – 85-25,000 Hz
  • Sensitivity – 88 dB
  • Impedance – 4 Ohm

Summary

Like in any other car, also in Jeep Wrangler TJ factory speakers are less than mediocre. It is not just about their size or position in the car, but design. They sound like cheap headsets from the last Century, which means anyone who wants to enjoy listening to music while driving has to replace them with aftermarket speakers.

Replacing speakers in TJ is not complicated, and we have, in this car, a unique possibility to choose from two different designs for the same location.

That is either oval 4″x6″, or round 5.25″. In both cases, we are looking for 2-way coaxial speakers, because Wrangler TJ does not offer a factory place for external tweeters that could be independently installed on top of the dash. 

Although having installed a component system would be a better option because of the higher location of the tweeters. Having high-quality coaxial speakers is also a great option when selecting speakers from a few good models we mentioned earlier in this article. 

The one key factor we should consider when searching for the aftermarket speakers is their sensitivity because inside the Jeep TJ can be really loud.

We do not want sound quality being destroyed by wind or tires noise, so installing speakers that can produce clear and loud sounds will be beneficial in the long term. Therefore the sensitivity of 90 dB should be the absolute minimum for front speakers in Jeep TJ.
