Many times one car speaker is louder than the other. The audio system of the car is upgraded by installing the speakers in the car.

Why is one car speaker louder than the other? It is common when one car speaker is louder than the other because of problems in the amplifier, wire connection, weak battery, issues with an RCA cable, and poor quality of speakers.

Usually, two speakers are installed in their car to improve their car audio system. The speakers are connected to the amplifier or car stereo, but sometimes the car speakers do not work correctly.

If you are facing this problem, then there will be several reasons behind it. Most people buy inexpensive speakers to save their money.

These low-priced speakers are not of good quality and also wear out quickly. Then, people spend more money on damaged speakers, but again these car speakers wear out. Consequently, the quality and brand of car speakers should be good.

The wires that are present between the car speaker and amplifier often break, and due to this, one car speaker produces a louder sound than the other car speaker.

The car speakers also get overheated due to less space in the car. It is advised that there should be an additional area for car speakers. You should select the durable and long-lasting speakers for your car.

Why is one car speaker louder than the other?

If the cord of the car speaker is short, then this can cause the low sound from the speaker and loud sound from the other speaker. The long wire keeps the audio quality of speakers stable.

The overpowering is not suitable for the car speakers as it can burn the car speakers.

Sparking wires

The wires often break or become loose, and the problem of sound in car speakers. It also happens when one of the wires is coming in contact with the body of the car.

The wires can also burn due to the overheating, and the speaker stops to produce a loud sound. It is suggested that you should check the wires of your car speaker if the wires are broken or loose then replace them with the new one.

If there is not a problem with the wire, then there could be another cause. The cones of the speakers are very sensitive, and people often turn the volume of the car speakers very high, and due to this, the car speakers stop working correctly. It is proposed that open the speaker and check its cone; there will be an issue with it.

Weak car battery

The weak car battery harms the speakers of the car. Two speakers in a car get more power from the battery. Due to this, the car battery may drain or die. The terminals of the battery often get corroded, and due to this, the one or both car speakers produce low sound.

Reversed polarity problem

The reversed polarity can cause the production of low sound from car speakers. You may insert the wires of the speakers in reserved polarity. The reverse polarity does not have a positive effect on the car speakers.

Due to reversed polarity, the car speaker produces loud sound as compared to the other car speaker. There are very few speakers that have the same polarity, while most car speakers do not have the same polarity. Therefore, your car speakers may have different polarities, and you have mistakenly reversed the polarity of the car speakers.

The wires of the speakers are both positive and negative, and the wires should be in the right place. It is recommended that check the polarity of your car speakers with the help of a multimeter to get rid of this problem. If you see the problem in the polarity of wires, then do correct them.

The issue in one car speaker

You may have turned ON the one car speaker and play it on the high volume for a long time.

You should not suddenly increase the volume of the car speaker. This act can decrease the performance of the car speaker. You should slowly increase the volume of the car speaker. You should also check and replace the broken car radio antenna.

Loose connection

The car speakers are connected with the amplifier or car stereo through wires. The connection between the amplifier and car speaker often becomes loose and disturbs sound quality.

The nuts through which the wires are connected may loose and cause this problem. It is suggested that if you have connected your car speaker with the amplifier, then you should check the connection of wires. If you see the loose connection between the car speaker and amplifier, then you should maintain the connection.

If the nuts are loose, then you should tighten them. The car speaker often produces low sound than the other when the wire of one speaker is crushed. You can use 8 ohm speaers in your car for better resuts.

One car speaker is louder because of a problem with cables

The loose cables of car speakers are the common cause of low sound from car speakers. The cables of car speakers may get corroded, and this causes the sound problem in the speakers. It is proposed that you should check the cables of speakers and if these are corroded, then you should clean them.

The fuse of the car speakers can cause this problem. When the fuse of car speakers wears out, then the sound quality of the car speaker decreases. It is proposed that replace the fuse with the new one because the fuse is not expensive and you will easily purchase it. You can add DAB radio in your Mercedes for better sound quality.

The cables that are connected to the car speaker maybe not of good quality. The speaker cables should be thick therefore you should purchase the good quality speaker cables. Due to damaged speaker cable, the service of the current disturbs, and one speaker produces low sound.

Space problem

If the space for the speakers is not sufficient, then the speakers do not produce sound appropriately. The extra space is mandatory for car speakers. If enough space is not provided to the car speakers, then the speakers do not work properly.

It is advised that you should select the sizes of the car speakers according to space in the car. Measure the overall diameter of the car speaker and then check the space in your car. The space for the car speakers should be equal or greater than the car speakers.

There should be enough space for the car speakers so that speakers easily fit in the car. There are numerous shapes of the car speakers; consequently, select the speakers according to space in the car.

Amplifier issue

If the edges of the amplifier touch the metal part of the car, then it can cause the problem of sound in the speaker of the car. It is suggested that check the edges of the amplifier, and if these are touching the metal, then cover the edges with the electrical tape.

By doing this, the loud sound will produce from both car speakers. The amplifier frequently gets overheated, and this may harm the performance of the car speaker. If the amplifiers make the speaker louder and efficient, then the amplifier can damage the car speaker.

If the proper power is not given to the car speaker, then the speaker cannot produce a loud sound. The low signals are transferred from the amplifier to the car speakers, and the car speaker does not run on the low signals.

The issue in RCA cable

The issue in RCA cable can cause the production of loud sound in one speaker as compared to the other. If the pin of the RCA cable breaks, then this can cause this problem. It is used to connect the car speaker with the amplifier, and it also affects the sound quality of speakers.

The signal between the speaker and other devices lost due to the broken RCA cable. It is suggested that check the RCA cable, and if the RC cable looks broken, then you should fix it.

The quality should be good because the low-quality cable wears out soon, and it also harms the car speaker.
