2002 Jeep Liberty

In a Nutshell

This article discusses how to install car audio gear in your Jeep. Check it out and then use our vehicle selector to find the gear that will fit your Liberty.

Your factory speakers are about to enter their second decade of existance, and that's a long time in "speaker years." Replacing them with new speakers will produce the most dramatic improvement in how your music sounds.

Installing a new receiver will give you a big bump in power, but you'll also get more functional benefits, like a USB input or Bluetooth® connectivity. To complete your Liberty's new system, boost your bass with a subwoofer and add a 4-channel amplifier to get maximum performance out of your speakers.

Full Story

Overview of the Jeep Liberty

The 2002-07 Jeep Liberty Sport is a compact SUV that's as capable of tackling the rocks and trails as it is at handling city streets. This rugged little vehicle is Jeep's response to the success of smaller SUVs like the Honda CR-V and Toyota RAV4.

The Liberty factory audio options were somewhat limited. You could choose the base system with a cassette or CD receiver in the dash, powering big 6-3/4" speakers in all four doors. Or, you could step up to the Infinity system, with a CD/cassette receiver or in-dash 6-disc changer/receiver, and an amp on each side powering both door and dash speakers.

If you want to take your tunes to a new level and enjoy them off-road, you'll have plenty of options for this Jeep, ranging from a new CD receiver and speakers to serious bass from a custom-fit enclosure.

This article is an overview of your vehicle's audio system and its upgrade options. If you're looking for step-by-step instructions on installing a car stereo or speakers in your Jeep, we'll include a Crutchfield MasterSheet™ free with your Crutchfield order, or you can purchase one for $9.99.

Factory stereo system

Base system: The factory system is equipped with six speakers, a CD player with CD changer controls and a fixed mast antenna. The Liberty accepts a DIN (2" tall) receiver with 7.89 inches of room to work with, so any single-DIN radio should easily fit into the space with a mounting kit.

You will also need a wiring harness if you don’t want to cut and splice any of the factory wiring, along with an antenna adapter that connects the Liberty antenna cable to the new receiver. The dash kit and harness needed for this installation are available at a deep discount with all Crutchfield receiver orders, along with our free step-by-step MasterSheet™ instructions for your Liberty.

The one downside to replacing your factory receiver is that you will lose the ability to talk on your phone using the hands-free system if you had this option from the factory. You’ll have to add a Bluetooth® adapter to the new receiver you install or, better yet, pick a car stereo with built-in Bluetooth connectivity.

Infinity system: The upgraded Infinity system came with six premium Infinity speakers in place of the six standard speakers. The 6-3/4" speakers in the front doors have amps on them that power the front and rear door speakers, along with the dash speakers, for better sound quality.

You'll go through the same process to replace the radio in the Infinity system as you do with the radio in the standard system, and you'll use the same kit, harness, and antenna adapter. The only difference is that the new stereo is tied into the Infinity amps in each front door. You'll get better performance out of your Infinity speaker system with a new stereo in the dash, but you also have the option of bypassing the Infinity amps by running new wire to all of the speakers.

Tools needed: Panel tool, Phillips screwdriver


Steering wheel audio controls

It's relatively easy to retain your Liberty's steering wheel audio controls when you install a new stereo. When you enter your vehicle information, our database will choose the adapter you need to make your factory steering wheel controls work with your new receiver.

Replacing your factory speakers

Base system: The Liberty’s front and rear doors house 6-3/4" speakers, and big aftermarket 6-3/4" speakers are the easy fit. But you can also put in 6-1/2" or 5-1/4" speakers with the help of a speaker mounting bracket, so that increases your choices. Jeep uses 2-ohm speakers in all of the doors so you’ll want to use Infinity, JBL, or other 2-ohm speakers to replace these if you’re keeping the factory radio, or you'll lose some output. You’ll keep the factory speaker grilles for all of these speakers.

All four of the door speakers are the same size and are pretty straightforward to remove and replace. You’ll need to remove the door panels (two Phillips screws and eleven plastic clips around the edge of the door panel), remove the speaker from the door (three Phillips screws) and disconnect the speaker.

No wiring harnesses are available to plug into the factory speaker connectors used in the Liberty, so you’ll have to splice the new speaker wires to the factory wires, or use a set of Posi-Products speaker connectors.

If you're installing a speaker with a mounting bracket in the front or rear doors, you'll need to cut or remove the rain shield between the door panel and the door, to gain more clearance for the speaker magnet. You can use speaker baffles to protect your new speakers if you remove the rain shield.

Infinity system: Each front door has an amp attached to the speaker that powers the 6-3/4" speaker in the front door, the 6-3/4" speaker in the rear door, and the tweeter in the dash.

You have two choices when you replace the Infinity system's speakers: 1) run new speaker wire from the speakers to your new stereo (or adapt the existing wiring); or 2) you can actually remove the Infinity amp from each front door factory speaker, and use it to power your new speakers. You’ll need to extend the speaker wires a few inches to reach your new speakers.

These speakers can be replaced by tweeters, so installing a component system is a smart choice for the Liberty (Crutchfield Research Photo)

Dash speakers

You have a 2.8" 4-ohm speaker located in each corner of the dash in your Liberty, wired in parallel off the front door speaker. You will have to fabricate mounting brackets to install the tweeters that are part of a component speaker system, but you can keep the factory grilles.

Getting to these speakers takes some work. You’ll have to remove both pillar trim panels (T20 Torx driver or 5mm ratchet and socket) and pry up the front edge of the dash trimpanel to release 13 metal clips. Two Phillips screws hold the speaker in place. You’ll need to use Posi-Products in this location, too.

Tools needed: Phillips screwdriver, small flat-blade screwdriver, panel tool, wire strippers, crimper and connectors (or Posi-connectors), electrical tape


Jeep Liberty cargo area

There's plenty of room for subwoofers in this Jeep (Crutchfield Research Photo)

Bass in your Jeep Liberty

If you're just looking for a little low-end reinforcement, you can install a small powered subwoofer under a seat.  The Liberty's cabin is relatively small, so you might be surprised by how much punch you'll get. And  the cargo area is easily big enough to hold a subwoofer box and still give you room for other, less-important cargo.


Other options for your Liberty

Here are some other ways to improve your Liberty's sound and functionality:


The factory Infinity system has two small amplifiers attached to the speakers, but these won’t give you the best sound when you upgrade your receiver or speakers. You’ll get the best sound quality when you bypass or remove the factory amps and go with a new aftermarket amp to power all the speakers. You can fit a new amp underneath the front or rear seats of the Liberty to keep it out of the way.


The Liberty will only accommodate single-DIN receivers, so an aftermarket GPS receiver won't work for this vehicle. Portable navigators do a great job, and you can move them from vehicle to vehicle, which is good news if you drive more than one vehicle.

iPod® control

If you don’t want to upgrade to an aftermarket receiver with built-in iPod controls, you can still add this little luxury pretty easily with an adapter that connects your iPod to your factory radio. Whether you choose a receiver or an adapter, you'll need to remove the factory radio and plug the iPod control into the back. Adapters are available for almost any version of the Liberty, but some won’t work with a factory radio that has a CD changer.

Security systems

Installing a security system in your Liberty isn't easy (security systems rarely are), but it's definitely a good idea. Our Crutchfield Advisors can help figure out what you need to get the job done, but we usually recommend taking your car and new gear to a professional installer.

    Thank you so much and great post! I have a question which I've been struggling with and I hear different answers everywhere. I have an 04 Jeep Liberty Limited Edition with the Infinity sound system, I'm looking to upgrade to a Pioneer Double Din stereo, I already bought the dash kit to convert the 1.5Din to 2Din. Someone told me you need to buy some kind of interface for the amplified speakers to work, otherwise the radio will turn on but will have no sound. Is this true? Another option is to bypass the infinity amps by running new wiring to the radio which is something I definitely don't want to do. What is it exactly that I need to upgrade to an aftermarket stereo? Thanks in advance and hope you guys can answer my question!!

    According to this forum the jeep liberty doesn't have tweeters in its dash it has small speakers that look like tweeters. can you confirm if this forum is correct or if you guys are correct? Thanks.

  • Jon Paulette from Crutchfield

    Posted on 11/9/2015 4:32:55 PM

    Vince, Good question! Those are full-range speakers, but they're small (2.8") and the only thing that'll fit in that space without modification is a tweeter. We'll be much clearer about that from now on, so thanks for bringing this up. BTW, the 3.5" JBL GTO329 speakers the forum folks talk about can fit in this location, but there's a bit of work to be done.

    Is there an adaptor to hook up to this radio for bluetooth? I have this same radio in my Ram. I have the ipod module connected now but really don't use it.

  • Jon Paulette from Crutchfield

    Posted on 12/18/2015 1:11:16 PM

    Bo, It depends on whether you want to add Bluetooth connectivity for hands-free calling or music streaming. There are several universal adapters for phone use, but if you're into streaming from your phone or another device, replacing the radio is probably your best bet. One of our expert advisors can help you find what you need, so give us a call.

    the double din kit is matte black. Does this replace the bezel or does the bezel install over it. My liberty is a limited and the bezel is a sort of silver metallic.

  • Jon Paulette from Crutchfield

    Posted on 3/8/2016 2:52:50 PM

    Dan, The only kit available at this time is the matte black model. And yes, it does replace the factory bezel.

    i have replaced my 2004 Jeep Liberty factory radio with a Kenwood KDC-152 head unit. The unit works, It turns on and functions well, BUT when I start the vehicle, it reads "NO BUS" on the instrument panel and immediately shuts off the whole vehicle. When I unhooked the head unit, the vehicle started back up and works fine. Is there any way around this??

  • Jon Paulette from Crutchfield

    Posted on 3/14/2016 9:36:14 AM

    Darren, That's not good. If you bought your gear from Crutchfield, you can call Tech Support for free help troubleshooting your system.

    I have some 6 1/2 in speakers that I would like to put in my 2006 liberty. What kind of adapters am I looking at to install these into the doors. Thank you.

  • Jon Paulette from Crutchfield

    Posted on 3/18/2016 8:45:30 AM

    David, To install 6-1/2" speakers, you'll need adapters and mounting brackets. Also, it's important to note that the factory speakers are 2-ohm models. You'll want to use Infinity, JBL, or other 2-ohm speakers if you're keeping the factory radio, or you'll lose some output. I've sent your question to our sales team, and they'll be contacting you via email soon. For immediate help, you can contact them via phone or chat.

    Any way to tell if you have the infinity system without taking out the speakers?

  • Jon Paulette from Crutchfield

    Posted on 3/20/2016 3:19:07 PM

    Jay, The Infinity system has amps in each front door. Just pop the door panels and take a look to see what you have.

    I have a 2006 Jeep Liberty that I have installed a KDC-BT562U head unit into. I'm now looking to replace the four door speakers with aftermarket speakers. I plan to adapt the existing wiring and bypass the amps in the front doors because one of them (driver side) is out. Is the wiring that powers the super small dash speakers coming from the amps on the front door speakers? If so, how would I adapt the existing wiring to allow for all 6 speakers to be powered by the aftermarket head unit I have in when I'm replacing the door speakers?

  • Jon Paulette from Crutchfield

    I have a 2007 Jeep Liberty. Is it a crazy question to ask if the iPod adapter works with IPhone 6 or just iPods? I just want to connect my iPhone as a aux source for music and maybe audio from maps. I would prefer to keep the factory audio units if I can.

  • Jon Paulette from Crutchfield

    I already have an Alpine aftermarket radio installed in my 2006 Liberty Limited. It has a harness adapter that uses rca's to the powered speakers. It not loud enough when I'm on the highway with the windows open. Can I install the Alpine pocket amp into the factory harness and leave the Infiniti amps on the speakers?

  • Jon Paulette from Crutchfield

    Posted on 5/11/2016 10:06:01 AM

    William, You'll want to bypass the old Infinity amps when you install a new amp. It's a worthwhile thing to do, because the new amp will send more power to your speakers and give you more volume and clarity.

    what size are the screws that connect the factory infinity amps to the factory infinity speakers,,,,my factory amps were just hanging in my door and I bought new factory infinity speakers to go back in my 06 liberty but the amp screws that mount the amp to the speakers were missing

  • Jon Paulette from Crutchfield

    Posted on 9/12/2016 9:57:01 AM

    Josh, We don't have any specs on those screws, unfortunately. You might want to check a Jeep owners' forum to see if anyone in the Jeep community has the info you need.

  • Bob Durkee from Tulsa

    I was replacing the front door speakers on my 2002 Jeep Liberty, but lost all sound from the stereo. The stereo is still working (changing stations, accepting CD's) but no sound. Thoughts?

  • Jon Paulette from Crutchfield

    Posted on 12/12/2016 9:08:07 AM

    Bob, It's probably just a bad connection. Check the door speakers again and make sure those connections are okay. Be sure to test the speakers before you put the panels back on. If that doesn't do it, the connection problem might be on the receiver side. And if you bought your gear here, you have free access to our tech support team for the life of the gear, so give 'em a call.

    hello, do you know the dimension of the stereo? my is a 2006 jeep liberty sport. I think is a 1 din head unit, but not sure. Im plannig to replace it with a in-dash retractil unit. Thanks,

  • Jon Paulette from Crutchfield

    Posted on 2/3/2017 9:36:00 AM

    Thomas, Those retractable receivers are cool, but they won't work in this Jeep. The good news is that a wide variety of single-DIN (1" tall) and double-DIN (4" tall) receivers will work, but you'll have to modify the inside of the dash a bit to get the DD models to fit. When you enter your vehicle's info into our Outfit My Car tool, you'll see which stereos fit your car, plus the correct harness. If you have any questions, our advisors are available via phone or chat.
