Major Reasons Why One Speaker Sounds Louder

Swap the Speakers:

The simplest way to check is to swap the speakers and also swap their cables. Once you swap the speakers, then you’ll notice either the problem is in the speaker or something else.

You can see either the speaker is faulty or the issue lies elsewhere.

Always be sure speaker wire ends are in good shape before swap your speakers. Also, make sure that stray strands of wire are not sticking out.

If you swap the speaker and the problem remains on, then probably the problem is in the signal source. Before it, you have to switch on your speaker and listen for a while.

Sadly most of the speakers do not have the best switch. On Amazon, you can find plenty of top rated speaker switches and you can check specific product recommendations.

You can choose your applicable one once you have a bad switch.

If the sound is roughly the same, that indicates the problem is with the signal source. But, why is an audio signal important? It’s important because it takes the audio signal from source to output.

This output of the amplifier is connected to speakers and converts an electrical signal into sound. If the speaker doesn’t get proper power, then it cannot produce a proper sound. 

The signal between the speaker with other devices failed due to the broken RCA cable. Bad RCA cable can cause a sound louder in one speaker compared to the other.

So, you have to check the RCA cable. Once you notice a broken RCA cable, then you have to fix it.

Keep into consideration that the quality of the RCA cable needs to be good. Because quality less cable wears out soon, and also harms the speaker.

In the end, if there’s no problem with the wire, then there would be another reason. The possible reason for the problem is with the connections. 

Check The Connection:

You have to not only check the wires but also check the connection of wires. The connection between the speaker and amplifier is sometimes loose and makes tough quality sound.

The nuts which are connected through the wires may lose and occur this problem. You should maintain the connection when you find a loose connection between the speaker and amplifier.
