Why Are My Rear Car Speakers So Quiet? Let us look at the possible reasons and what you can do about it.

While the engine noise is music to some, nothing can beat a good sound system because what else will you do on long drives? However, despite investing in good sound systems and vehicles, something can be off and fixing it becomes essential.

Why Do My Car Speakers Sound So Low?

Here are the possible reasons owing to which your car rear speakers sound low.

Loose cabling

A common cause of quiet speakers is loose cabling. Loose cabling in the car can lead to low output, and inspecting the same on your own can be an arduous task. Look for continuity; if you can’t see continuity, it is indicative that the wire is broken. 

Fewer Rear Car Speakers

Maybe the rear speakers in your vehicle are less. Yes, things can be as simple as that, sometimes. 

The amplifier is in contact with the metal within the housing.

Ensure that no part of the amplifier is in contact with the housing while out of its housing. Covering the area with some electrical tape can be a fix to this. 

Insufficient to match the audio power

Suppose your speakers tend to get quieter at higher volumes. In that case, this can be because they are insufficient in matching the power from your audio. They need much higher output, and this issue can be rectified by installing an external amplifier, more details of which we will see in the questions below.

Why Are My Back Speakers Louder Than My Front Speakers?

Rear speakers are louder than the front speakers because the rear speakers and the front speakers might have an incompatible impedance rating. It is also possible that they have a higher or lower sensitivity as compared to the head unit.

How Can I Make My Car Speakers Sound Better?

Here is a list of things you can try hands-on for bettering the sound of the car speakers. 

Upgrade the head unit and kiss goodbye to the phone’s built-in DAC

The audio quality takes a hit when playing audio from an MP3 player or a phone and an auxiliary connection. To begin with, get hands-on a replacement head unit that has a USB connection. You should consider this even more if your head is getting old or doesn’t have preamp outputs.

If your existing head unit doesn’t have a high-quality built-in DAC, you can consider adding a new head unit. Adding a new head unit will allow you to offload the heavy lifting of digital audio conversion from your phone or MP3 player to your car stereo. 

Add components such as signal processors, amplifiers, and equalizers.

If the factory car audio systems are oversimplified, one can consider an upgrade. Incrementally add new components, such as a new amplifier. An amplifier can transform the audio quality considerably.

If the stereo in your car doesn’t come with an amplifier, find a unit that comes with speaker-level inputs. One can carry out this upgrade by installing a head unit with preamp outputs and an amplifier that includes speaker-level inputs.

Install sound dampening materials.

Add sound dampening materials such as insulation sheets or spray foams to quiet your car’s interior. Even when you choose not to play any audio, you will enjoy the quieter environment inside the car. 

Get the new audio car system installed by an expert.

Although this will be heavy on your pocket, the result is certainly worth it.

How Can I Make My Rear Car Speakers Sound Better?

One can make the rear speakers of their car sound better by doing the following. 

Try increasing the volume of the car speakers on your own by…

Locate the fuse panel in your car. Your car’s manual can come in really handy for locating this. Open the fuse panel, and you can get access to the fuses.

Remove the fuses for a closer inspection. Look for burns or cracks on any of the fuses. If any fuse appears damaged, replace it or get it replaced. Now, using a screwdriver, remove the amplifier. Check all the cables to plug them in the right positions. If any cable isn’t in the right place, put it where it should be to finish off.

Installing an external amplifier

Your rear car speakers do not match up the power of your audio, and they need much higher output. Installing an external amplifier can hence be a good solution. 

Here’s how you can install an external amplifier in your car to fix the quiet sound. We strongly advise reading the manual to acquaint yourself with what you are going to do. 

Step 1: When choosing an external four-channel amplifier to power your front speakers, ensure it matches the same RMS power as the speakers themselves. One must do this carefully since overpowering the speakers can blow the coil inside them. 

Step 2: Position the amplifier at the desired location inside the vehicle. After that, mark the location of the same using an appropriate marker. Double-check the surface beneath lest it houses any wiring, tanks, or the likes.

For example, installing an amplifier in the engine compartment of the vehicle can nullify the guarantee. Drill the attachment holes wherever needed and make use of the four attachment screws provided with the amplifier. Use good-quality connectors to ensure a reliable and safe installation process. 

Step 3: If cabling the system properly on your own seems impossible, reach out to a local distributor. There are several things to be addressed. For starters, avoid routing power supply cables to low-level input cables. Any wire routed through metal must be protected with a grommet. Also, route the wires away from sharp objects, which are likely to cause damage. 

Step 4: Run the red power and connect it to the plus on the battery. Ensure that your fuse holder is connected to your car battery. 

Step 5: Connect the other end of the red power wire to the terminal voltage on the amplifier. 

The functions, settings associated are likely to vary from brand to brand. One must hence check the manual to have a fair idea of the instructions.

Use foam baffles to reduce the noise.

Foam baffles fitted to your speakers will help reduce resonance between the panel and the frame for better sound. They can also reduce external noise by dimming vibrations that enter your vehicle from behind the cone of the speaker. Not only this, but foam baffles also keep dirt and dust at bay which is essential for the longevity of your speakers.
