Can RCA Cable Be Used as a Speaker Wire? Easy Explanation

While connecting the subwoofer to the speaker, generally speaker wires are used. Now let’s assume that you have an issue with the speaker wire or you may need to change the connector of the speaker wire. Unfortunately, you don’t have an extra speaker wire but have an RCA cable with the connector.

You checked out and found both look the same; now you are wondering whether you can use the RCA cable as a speaker wire or not. Well, in that case, the answer is both yes and no. Using an RCA cable as a speaker can have a negative impact on the speakers.

To learn more, stay with us till the end and find out whether you can use the RCA cable or not. So, without any further ado, let’s begin then.

Is It Possible to Use RCA Cable as a Speaker Wire?

First of all, both RCA and speaker wire are totally different things. One is responsible for carrying audio signals, and the other one is for carrying a larger amount of power. Generally, it won’t be an ideal choice to use an RCA cable as a speaker wire.

Now let’s find out, why it can’t be possible. There are two fundamental reasons that demotivate the users to use RCA cable as a speaker wire. 

1. Different Architecture

If you look at both RCA and speaker wire cables, you will find that the thickness of the RCA cable is lower than the speaker wire. For speakers, a thicker speaker wire is needed. Moreover, RCA cable has lesser insulation than speaker wires.

For these reasons, there is a chance of higher electrical resistance. 

2. Signals Compatibility

The RCA cable isn’t compatible with the signals carrying requirement for speakers. Generally, speakers require higher-level signals and the RCA cable is capable of carrying lower-level signals. Due to this, the RCA cable failed to handle the output of the amplifier. 

What Will Happen if RCA Cable is Used as Speaker Wire?

Technically, it’s possible to use and we have stated above that you can use it. Well, that was answered in a sarcastic way though. Generally, the answer is not. But if you still want to use the RCA cable as a speaker wire then the following issue you will face,

• The speakers won’t get adequate signals as the RCA isn’t capable of carrying high signals.
• Have interference issues and won’t get proper sound experience.
• Using an RCA cable can damage your speakers.

So, if you are willing to disturb your sound experience or blow up the speakers, then here you go, you can use the RCA cable as speaker wire without any issues.

To Sum Up

Well, it’s ideal to use only the speaker wire rather than the RCA wire if you want to keep your hearing experience and the speaker safe. It’s always better to avoid using inappropriate things when you are using an electrical device. Hope this article helps you out. If you have any questions, then let us know in the comment box below.
