2001-2005 Honda Civic sedan

Upgrading the stereo system in your Civic
2001 • 2002 • 2003 • 2004 • 2005

2001 Honda Civic LX sedan

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

Overview of the Honda Civic

Thanks to near-legendary reliability, affordability and efficiency, the Honda Civic has long been one of the most popular cars around. They're also known for impressive longevity, so if your seventh-generation Civic is still running strong, a new stereo is probably a wise investment.

Designing a stereo system that suits your musical tastes is one way to make your Civic stand out from the crowd. There are plenty of simple upgrades that will make a big difference in your car's sound, not to mention a variety of add-ons that will allow you to use all of your favorite electronic devices with your car stereo.

Factory stereo system

The standard stereo in the Civic is an AM/FM/CD radio with the option for a CD changer. The sound system is rounded out by either a 4- or 6-speaker configuration, with standard factory sizes that make upgrading easy.

Replacing your factory radio

After you remove a few dash panels, getting the Civic's factory stereo out of the dash is a snap. The dash opening also accepts any single-DIN (2" tall) or double-DIN (4" tall) stereo with help from a dash kit that's available at a deep discount when you shop at Crutchfield.

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.

How you use your Civic will help you decide the best choice for you, so pick the stereo that will do all the things you need it to do -- plus a few things you might want it to do eventually -- so you can avoid having to upgrade your system again in the near future.

If your car has a factory CD changer, it won't work with a new stereo. But the loss of that component will be made up for by a dramatic improvement in sound quality and the more modern features of most new receivers.

Tools needed: Phillips screw driver, flat-blade screw driver, 8mm driver, panel tool

Steering wheel audio controls

It's relatively easy to retain the steering wheel audio controls when you install a new stereo in your Civic. 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.

Hybrid note

The Civic Hybrid's gas-electric hybrid powertrain makes replacing the stereo is a little more complicated. As you might expect, these cars contain some very sensitive electronics, so here are a couple of things to keep in mind:

  • Be sure to only use a multi-meter when testing wires, and NEVER use a test light to test wires in this vehicle. Doing so could cause some serious (by which we mean dangerous and expensive) damage.
  • A Civic Hybrid is not the car to choose if you want to build a massively powerful audio system. The thirsty current draw of a high-powered stereo is not a good thing for the hybrid system, so don't exceed a 30-amp current draw or 350-watt RMS power rating.

Replacing your factory speakers

Front speakers

Your Civic came from the factory with one of a couple of speaker options for the front doors: a standard 2-speaker setup, or a 4-speaker configuration with tweeters in the sail panels.

Most 6-1/2 inch speakers fit easily with the help of a mounting bracket, and the common size means there are upgrades for any budget. The factory speakers are kind of an odd size, so you'll have to drill some new screw holes to replace your speakers no matter what you put in there.

The larger size also makes it possible to get solid low notes, and adding a set of component speakers will give you a full, rich sound up front, right where it should be. The door panels are easy to remove to get to all the necessary connection points, so it's a great way to get comfortable with doing your own upgrades to your Civic’s stereo.

Rear speakers

The rear shelf speakers in the Civic sedan are a simple, bolt-in upgrade, with large openings that hold 3-bolt 6-3/4" 3-ohm speakers. A set of 5-1/4 inch speakers are the easiest fit, with the help of mounting brackets, but some 6" x 9" models can work, too. Our database will show you what works for your car.

There are several interior panels that need to be removed to get to the factory speakers, but removal and installation is straight-forward and yields big results. Again, you’re only limited by your budget, and swapping out these rear speakers will really fill out the sounds in your Civic.

Tools needed: Phillips screwdriver, flat-blade screwdriver, 10mm driver, panel tool, drill and a 1/8" bit

Bass in your Civic

Honda didn’t put much thump in the Civic, so adding a subwoofer will really wake up any style of music. The Civic has impressive trunk space for a compact car, so there's plenty of room to add the necessary amp to go along with a sub and enclosure. Make sure you pick a deck with preamp outputs to make installation easier, and match your new sub to an amp with enough power to push it. If you're looking for something simpler, try a powered subwoofer.

Other options for your Civic

There are plenty of ways to improve your Civic's audio and entertainment quality. Here are some of our favorite stereo upgrades:


No amps were offered from the Honda factory, but they’re a must if you want the best possible sound. Just how much sound is up to you, but a good place to start is added power for your front speakers. If you’re adding a sub, you’ll also need a way to power it, so look at multichannel amps that can handle the subwoofer and your door speakers. There is plenty of room for the additional juice, with ample trunk space and room under the seats.

Satellite radio

This wasn’t an option on your Civic, but it's a necessity if you find yourself on the road a lot. Most receivers have the ability to add and control SiriusXM tuners, or you can pick up a portable satellite radio that can be easily transferred between vehicles. Your favorite stations will be right there wherever you go, and you’ll love the variety of music, sports and news, as well as hearing music you probably wouldn’t ever hear on terrestrial radio.


With so many Civics being utilized as commuter cars, a navigation system can really come in handy. You can go with an in-dash GPS receiver, or you can choose a portable GPS device. The portables are easy to move from car to car, packed with handy points of interest and come with trusted software and maps pre-loaded for your journey.

Remote start and security systems

Adding remote start capability to your vehicle lets you warm it up in the winter or cool it down in the summer. The iDatastart system is incredibly convenient and makes it easier than ever to install a remote start system, so we highly recommend it. The module requires a vehicle-specific T-harness (sold separately) to connect with your vehicle's computer, security, and ignition systems, so we ask that you call to order so that we can make sure you get the right harness for your ride.

You can also talk to your Crutchfield Advisor about a security system. They’re not as easy to install (we usually suggest letting a professional do the job), but we can help you choose a system that’ll work in your vehicle.

    My amp cuts out when i go above 20 mph and comes back on below 20 mph I have no idea why

    Jason, The first thing we'd suggest is to check your wiring connections. If you bought your gear from Crutchfield, you can call Tech Support for free help troubleshooting your system. If you purchased your equipment elsewhere, you can still get expert Crutchfield Tech Support - 90 days-worth for only $30. Check out our tech support page for details.

    Mark, That should work fine, but you'd get obviously get even better performance with an aftermarket receiver. 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.

    I have a 2003 civic lx. I am planning to buy Kenwood front door and rear deck speakers. The front pulls 3 ohms and the rear pulls 4. Can the factory system handle the Ohm?

  • Craig

    Posted on 5/20/2020

    If the rear speakers are 6-3/4 inch stock, why do you recommend 5-1/4 inch? Doors and rear deck, would it be wise to remove the factory grill and fabricate a way to use the grills that came with the speakers?

    Jon Paul from Crutchfield

    on 5/21/2020

    Craig, It's not a question of size in this location, it's a question of what can fit into the cavity without modification. As for the stock grilles, they're completely integrated into the doors and deck, so removing them would not (In our opinion, anyway....) be the most practical or attractive thing you could do.

    Kevin, Sounds like you're trying to go inside-out, but according to our expert techs, it might be easier to try starting from the outside (the engine compartment) and bringing it through to the inside. For instance, you could go through where the hood release cable passes through the firewall. That's just one idea. If you bought your gear from Crutchfield, you can call Tech Support for free installation advice. If you purchased your equipment elsewhere, you can still get expert Crutchfield Tech Support - 90 days-worth for only $30. Check out our tech support page for details.

  • Kevin Vagen from Canton

    Where are you guys going through the firewall for power to the trunk? I'm trying to go through the grommet under the glove box, but it's behind a plate in the engine bay, so while it seems clean, I think I need to do a 90 degree sweep. I'm with a ES9 Hybrid.

    I have a 2004 Civic EX and after replacing my head unit with an aftermarket i no longer have sound in the rear speakers. The fronts work fine and all settings are set to center fade. All speakers are new and i rechecked the wiring from behind the new unit to the rear speakers themselves, so all speakers should work, any ideas? Any help would be appreciated. Just trying to enjoy my new investment.

    James, That's a bummer. If you bought your gear from Crutchfield, you can call Tech Support for free help troubleshooting your system.

    If I'm trying to add a single din radio would I still need to use a dash kit or is that just for a double din

    Jon Paul from Crutchfield

    on 3/25/2019

    John, Yes, you will need to use a dash kit for the single-DIN receiver. The cool thing is that you'll save money on it when you buy your receiver at Crutchfield.

    What size speakers would fit for the rear speakers on a 2004 Honda Civic Ex coupe ? Thanks you

    Jon Paul from Crutchfield

    on 2/18/2019

    David, You have a few options for the rear deck in this car. 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.

    I have a 2001 civic ex coupe. Would you be able to help me find out the biggest box dimensions I could fit in the trunk. I have an emf banhammer 15 that calls for like 4 cubes and I wanna tune the box to 33ish. Also id like to build the box outside the car. Dont know if that changes anything just dont want it to be permanently in the car.

    Jon Paul from Crutchfield

    on 2/12/2019

    John, Your Civic coupe offers a 41"W x 15"H x 32"/36"D (top/bottom) space to work with, so you do have some space.
  • Christian from Fresno

    do you guys know the max dimensions for a 2003 Honda civic lx sedan trunk just wondering so i know whats the biggest box i can build for it ? (already built one was too big apparently i dont know how to measure)

    Jon P. from Crutchfield

    on 8/31/2018

    Christian, According to our measurements, you should have a 40" W x 14" H x 34"/36" (top/bottom) D space to work with. Measure twice, cut once, work carefully, have fun, and when it's all done, visit our Custom Car Showroom and show us how it turned out!
  • Jon Paulette from Crutchfield

    Posted on 4/30/2018

    Christian, If you're trying to blend those in with your car's factory system, you might want to keep it in the 250-300 watts RMS range. But two 12's on a 1000-watt amp can totally rock. Give us a call and talk to one of our advisors about the system you're trying to build. We can help you find exactly what you're looking for.

  • Christian from Fresno

    Posted on 4/28/2018

    Im getting a Honda civic 2001 and I was wondering if hooking up 2 12s with a 600-1000 watt amp would it be to much for the car?

  • Jon Paulette from Crutchfield

    Posted on 1/7/2018

    Charlie, So we did. For the record, we were right the first time. Fixes applied, and thanks very much for the heads-up!

    You added that double Din fits at start of article, but left the conflicted info that it does not towards the end.

  • Jon Paulette from Crutchfield

    Posted on 11/16/2017

    Matthew, Honest answer? Because the article really needed some updating! Correct info has been added. Thanks for the heads-up!

  • Matthew Keen from Marysville

    Posted on 11/15/2017

    How come it says that double din won't fit in civics dash but on your shopping website it says that they will fit

  • Jon Paulette from Crutchfield

    Posted on 11/9/2017

    Noah, Not without some pretty heavy mods, and that's assuming they'll even connect to the factory wiring. You're better off selling those old speakers to a Z-Car enthusiast and putting the proceeds towards a set of 6-1/2" or 5-1/4" aftermarket speakers.

  • Noah Johnson from Thousand oaks

    Do you think I could throw 6.75" kicker speakers in my door? They are from an old Nissan 350z and I was hoping I could make good use of them

  • Jon Paulette from Crutchfield

    Posted on 3/22/2017

    Ben, We're a bit hesitant to get into OEM-OEM swaps, but you might find that info on a Honda owners' forum. We'd still recommend letting our Kit Finder tool show you the speakers that will fit your car. When you order from Crutchfield, you'll also get a healthy discount on the brackets and adapters you need.

  • Ben from Mechanicsville

    Posted on 3/21/2017

    Will the 06 speaker bracket and wire adapters fit the 04? They look identical. I would imagine that they are interchangeable. The 06 looks like a better design, but would still fit.
