Honda Civic Speakers Not Working

When you’re cruising in your Honda Civic and the speakers stop working, it’s the most annoying thing.

But don’t stress out too much, as it’s usually a simple process to check and sort out the problem.

When your Honda Civic speakers stop working, it is generally a wire that has come loose or frayed, or it’s a problem with the connection to your head unit. You may also have an issue with water getting inside the door when it rains or when you go through a car wash. This will short out the speaker.

The door speakers in a Honda Civic are 6½-inch and they’re really cheap off eBay or Amazon. You can buy two decent speakers for less than $20, so don’t worry if your speakers are damaged and need to be replaced.

To access the front speakers, you must remove the door panel.

Removing the door panel requires that you unclip the plastic panel that houses the door handle and window switches. Slip a screwdriver underneath the rear-facing end of the plastic panel and lift it up and forward. Don’t attempt to lever the front edge up as you will break the clip that holds it in place.

Once the plastic cover is loose, unplug the electrical connections. Then move on to the plastic cover that is located behind the door handle. It is held in place by a rivet and a screw. After unscrewing the cover, pop the rivet out by pushing on the center with a screwdriver.

You’ll have to hold the door handle in the open position as you remove the screw. You’ll also have to remove the screw holding the door handle in place. Once all the screws are removed, use a flat head screwdriver to pry the plastic clips around the edge of the door panel, free from the door frame.

Be careful that you don’t damage the wires leading to the locking mechanism. It’s not necessary to unclip them as you can access the speakers by moving the panel to one side.

A single Philips screw holds the speaker in the door frame. Unscrew it and then lever the plastic speaker-holder out of the door. You’ll have to lift the mount up and out of the door recess. When it’s out, unclip the speaker cable by pressing the connector tabs together.

You can then remove the speaker from the plastic holder and mount your new speakers inside.

To help protect the speakers from water getting inside and damaging them again, you can cover the connection with a foam baffle. This will cover the entire back side of the speaker. Cut the old speaker out of the plastic cover and break off the tabs that held it in place. This will give you space to push the new speaker inside the mounting bracket which you can then mount in the door.

The new speakers are wired to the connection in the door by removing the connector and joining the wires. You can either solder the wires together or use crimp-on connectors. Once connected, tape the joint with electrical tape for a water-resistant cover. You can also use the heat-shrink tube to insulate the connection.

Check the clearance between the speaker and the door panel speaker recess. You may have to remove a little of the plastic speaker cover inside the panel to allow the speaker and baffle to fit snugly inside.

Then test your speaker to see that it works before replacing the door panel and door handle cover.

Honda Civic Speaker Noise

Car manufacturers go to great lengths to ensure that you enjoy their cars. However, even the most reliable cars can develop problems with their sound systems.

When you experience a low-frequency noise or buzz coming from your Honda Civic speakers, you will likely have a problem with your amplifier. The stock head unit doesn’t send amplified signals but some aftermarket head units do. This means that the amplifier is amplifying an already amplified sound.

When the amplifier receives an amplified signal, it will switch the speakers on before the music starts playing. This will cause the speakers to emit strange sounds.

If you hear a popping or crackling sound when changing volume or when making adjustments, or if your speakers are playing really loudly when on a lower volume setting, then it is most likely your head unit pushing out an amplified signal.

If you hear a constant buzzing or low-frequency sound coming from your speakers, then it is probable that your head unit is at fault.

To fix the problem, you must connect RCA cables to the speaker harness wires so that you have both the positive and negative wires running to the RCA Cable connection.

The RCA cable dampens various frequencies by running a small positive wire inside the outer ground (negative) wire. This shields the positive wire and prevents any frequencies from escaping. The RCA connection sends low-frequency signals to the amplifier which stops the speaker noises.

Honda Civic Left Speakers Not Working

As cars age, various components within the head unit, the speakers, and the wiring harness can wear out.

When left Honda Civic speakers stop working, the problem can be a blown speaker, incorrectly set up balance and fade, a damaged head unit, or damaged wiring. Test the resistance on the speakers. If there’s a reading, then the speakers are fine. An infinite reading means the speakers are blown.

To test the speaker and the head unit you’ll need a multimeter.

To test the speaker, you’ll have to remove the door panel and then unplug the speaker. Once the speaker is out of the car, use the probes to test for resistance across the positive and negative terminals.

An infinite reading on the multimeter indicates that the speakers are blown and you will have to buy a new one. They usually come in pairs, so you can choose whether to replace both the right and left speakers at the same time.

If the speaker is fine, you’ll need to access the head unit.

Once you have access, test the voltage across the positive and negative speaker terminals. A constantly fluctuating reading shows that the head unit is sending a signal correctly, which means that the problem is due to a wiring issue.

You will then have to run a new wire to your speaker if you can’t locate a break in the wire or a spot where the wire has rubbed through the insulation.

If there is no voltage reading while music is playing, then your head unit is faulty and may require replacement.

Honda Civic Right Speakers Not Working

While a problem with your car’s speakers may be irritating, it’s not a difficult problem to diagnose.

If a Honda Civic’s right speakers stop working, you need to test the speaker to see if they are blown. You do this by testing the resistance across the positive and negative terminals. If there is a reading on your multimeter, the speaker is fine and points to a wiring problem or a faulty head unit.

Before pulling the head unit out of the dashboard to check it, have a look at the spot where the wires go through the door hinge area.

If your car is an older model, the wires may have worn through from the constant movement of the door opening and closing. This results in the wire insulation wearing through which can short out the speakers.

The solution is to replace the wires.

Honda Civic Rear Speakers Not Working

Often, you’ll not notice when the rear speakers start to fail, as the majority of the sound in your car is enjoyed from the front seats.

When a Honda Civic’s rear speakers are not working, check whether it is related to the head unit or the wiring by performing a simple resistance check on the positive and negative speaker terminals. If there is no reading on the multimeter, then the speakers are blown and require replacement.

The most common problem with rear speakers is that the wiring becomes worn or broken. If the speakers are fine, then you can check the wiring where it travels through the bodywork and doors.

The constant opening and closing motion of the doors wears the insulation on the wires, resulting in a short. To fix the problem, you’ll need to run a new wire from the head unit to the speakers.

Honda Civic Front Speakers Not Working

When your front speakers stop working suddenly, it pays to check that the balance and fade controls are correctly set before removing trim panels and accessing the dashboard.

To find the cause of a Honda Civic front speakers not working, perform a resistance check by putting a multimeter on the positive and negative terminals. If the speakers are fine, then check the head unit voltage on each speaker output. You can check the wiring if the head unit voltage is correct.

If there’s no voltage showing on the speaker output terminals when you play music through the head unit, then it is most likely faulty and will require repair or replacement.

How to Fix Honda Civic Speakers

No matter which model Honda Civic you have, replacing the speakers is a simple job.

To fix Honda Civic speakers, you need to remove the door trim. Then unscrew the speaker mounting plate and unplug the speaker. Replace the speaker with a similar 6½-inch speaker. You may need to purchase a mounting bracket for your new speakers. Plug the speaker connection in and test the speakers.

Before replacing your Honda Civic speakers, check the resistance across the positive and negative terminals. If you get a reading, then it means that the speakers are still fine and you may have a wiring fault or a broken head unit or amplifier.

If the resistance is infinite, then the speakers are blown and you can replace them.

The most difficult part of the job is to remove the door panels without damaging them or the electrical connections. There are 3 to 6 screws that hold the door panel in place. If you feel resistance from the middle part of the door when trying to remove the panel, check for the screw that you must have missed and remove it.

The plastic trim around the door handle covers one or two screws that you must remove to unclip the panel.

Once the panel is unclipped, disconnect the electrical connections by pressing the plastic tabs inwards.

The speakers are held in place by a single screw that you can remove with a screwdriver. Then pull the speaker out and unclip the connector. Insert the new speaker and clip it in place. Don’t replace the door panel until you have checked that the speakers work.

How to Make Honda Civic Speakers Louder

We all want our car sound system to sound fantastic and one of the ways to do this is by increasing the power output.

However, there’s no point in cranking up the volume if your speakers can’t handle it.

To make the speakers in your Honda Civic louder, you’ll need to install an amplifier and a subwoofer. The standard head unit puts out around 18 watts and the amp should put out approximately 25 to 50 watts per channel for you to hear a difference.

If you just want to boost the base, then you can switch off the head unit and then hold down the 4 and 6 buttons while pushing the power button.

The word “DIAG” will appear on the screen. Then push the number 4 button, which brings up the “DSP FLAT” message on the display. Next, push and hold the number 4 button until the display changes to “DSP OFF”.

Your sound system is now in DSP off mode and the bass output is increased. Turn your sound system off and then on again and test your music volume with the new settings.

If you plan on adding some new components to your sound system, consider investing in an amp first. Your head unit is not really designed to put out a huge sound, so adding an amp will not only enhance the loudness, it will improve the audio quality as well.

How to Replace Honda Civic Speakers

While the stock standard speakers in your Honda Civic give it a reasonable level of audio sophistication, adding new speakers will help improve the audio quality.

If your budget allows, adding in an amplifier and a sub-woofer will really boost your listening pleasure.

To replace your Honda Civic speakers, you can either replace them with equivalent 6½-inch speakers or you can upgrade to a better quality speaker with a higher output. For an additional boost, you can replace the old speaker wire with some new, high-quality wiring.

To replace your speakers, you must remove the door panels. The panels are secured by a few screws behind the door handles and plastic clips around the edges. Once you have removed the plastic trim panels and screws, use a plastic pry tool or a large flathead screwdriver to lever the panel free.

Unscrew the speakers that are held onto the door by a single screw.

You’ll need a speaker mounting bracket to hold the speaker in place and these are available from the parts store. If you don’t wish to spend money on a new bracket, you can cut the old speakers out of the plastic bracket and break off the plastic tabs that hold the speaker in place.

Attach the new speakers and check that they work before replacing the door panels.

If you decide to add an amplifier, you can ensure that the speakers match the power output from the amp by checking the specifications of both. After setting up the amp, consider restricting the lower frequency notes going to your speakers.

This will ensure that you have a crisp, clear sound quality. If you want to boost your base frequencies, then installing a subwoofer is the way to go.
