2002-2007 Jeep Liberty

Upgrading the stereo system in your Liberty
2002 • 2003 • 2004 • 2005 • 2006 • 2007

2002 Jeep Liberty

In brief: This Crutchfield Research Garage article gives you an overview of your Liberty's stock stereo system and your aftermarket upgrade options. Use our vehicle selector to find the gear that will fit your Jeep.

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.

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.

Detailed stereo and speaker removal instructions

MasterSheet image
With step-by-step disassembly instructions and plenty of up-close, detailed photos, our exclusive Crutchfield MasterSheet™ takes the guesswork out of removing the factory stereo and speakers. It's free with your Crutchfield order, or you can purchase one separately for just $9.99.

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.

Jeep Liberty dash 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

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.

Shop for vehicle-specific subwoofers for your Jeep Liberty

Other options for your Liberty

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

Amps

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.

Navigation

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.

    Is there a schematic or diagram stating the wiring colors that should be jumped/used or perhaps a procedure written somewhere with explicit instructions for bypassing the factory speaker mounted Infinity amplifier on my 2003 Jeep Liberty Limited? I can not find any instruction or wiring diagrams anywhere to help.

    Jordan, We can probably help with this, but with questions like this one, it's always better to have a conversation with a real live human. Give us a call and talk to one of our advisors. We can help you choose the right gear and give you the right advice on how to install it.

    Where exactly can I find the factory amp in my 2005 Jeep Liberty?

    Victoria, The Infinity system features two amps, one located in each front door. Each amp powers all of the speakers on the corresponding side.

    Just a quick question... The top of the article states that the Libby uses a 2 DIN head unit but can accept a 1 DIN with an adapter plate. Towards the bottom of the page, it states that it only accepts a 1 DIN unit, so no GPS. ?? Can you please confirm which one is accurate? Thanks!

    Terry, A single-DIN aftermarket receiver will work in the Liberty. Give us a call and talk to one of our advisors. We can help you choose the right gear and give you the right advice on how to install it.

    Hello so I just redid my 2005 jeep liberty speakers an new after market radio. Today I was driving it was working fine. I shut off my jeep to see an family member. Came back out turned it on an it says AMP ERROR on my new radio. I put new fuses in it thinking that was the problem of no sound at all radio works fine but no volume at all. Is there a stock amp in the jeep that I don't know about? How do I go about fixing this issue I'm so mad I literally rebuilt this entire jeep from bottom to top. An everything is brand new can someone please help.

    First time visiting this site, but I'm looking to make a purchase with you guys so I can upgrade my ride. I have an 04' Jeep Liberty Limited with the Infinity system, and I want to get rid of the front door amps and replace all four door speakers and the dash speakers. I understand that the amps in the front doors also power the rear door speakers, but I don't know how to actually go about the removal and rewiring of the door speakers. Also, I know the dash speakers are 2.5" but most tweeters only go to about 1.5", and I'm unsure of what will fit. If there is an easy bracket installation that would be ideal but I want to make sure power output won't blow anything if I go too small with the tweeters. Thanks in advance!

    My stereo system in my 2002 Liberty Jeep limited edition has the infinity with amp system. The stereo system started to have a Rhythmic popping noise when the engine is on. The speakers also goes in and out. These issues are not happening if the engine is off. I have checked the front door speakers and the connection are pretty good. Would you know what would be the issues? Thanks, Even

    Even, It's hard to say from here, obviously. It might not even be the radio or the amps, but you should check all those connections anyway. If it's not that, the issue will probably be hard to find, but our techs were wondering if you'd had any other work done to your Jeep lately. Sometimes one seemingly unrelated thing can cause issues like this. Hope that helps!

    In this article, it says that with the infinity system... the two ways to connect the new speakers is: 1) run new speaker wire from the speakers to your new stereo (or adapt the existing wiring) 2) you can actually remove the Infinity amp from each front door factory speaker, and use it to power your new speakers. Does the crutchfield car audio installation mastersheet show how to do method 1 (run new speaker wire/adapt the existing wire) or does it only show option 2?

    Matthew, We don't carry those subs, but we do carry sound deadening material. Adding some Dynamat to your Liberty can help with the rattling, so we'd suggest looking into that.

    I installed x2 Alpine SPS 110TW's in the dash along with x4 Alpine SPS 610's in the doors. Everything is hooked up to factory wiring. Both tweeters and four speakers are 4-Ohm. I have aftermarket HU with x2 RCA's (4-channel) going out to Alpine KTP-445U amp in glovebox. I have really bad distortion problems at higher volume levels w/ this setup, so I have to decrease the gain on the KTP-445U and then I don't have very good volume. Is this the result of using the factory wiring, which for the front tweeters and door speakers is wired in parallel? Basically its x4 speakers @ 4 Ohms (x2 tweeters @ 4 Ohms + x2 door speakers @ 4 Ohms). Trying to get more distortion-free punch out of my system.
