How To Wire Speakers To Amp?

Speakers are the devices that produce output in the form of sound as the result of any input. The sound produced by speakers can be any music. On the other hand, amplifiers are devices that are used to elevate the sound level making changes in its frequencies. 

Several components help the amplifier make their way and take help from speakers to amplify the sound for more significant effects and excellent sound quality. We will learn about some of those components in our way ahead in the article. 

Speakers consist of wires that are connected to the amplifiers in order to produce sound. The wire consists of two terminals, negative and positive. To connect to the amplifier, make sure that it is turned off. 

Speaker Terminals

Speaker terminals are the points that are connected through the speaker to the amplifier. Learning about this is fundamental knowledge that is needed when connecting speakers to amplifiers. These terminals play the role of transferring energy from the speaker to the amplifier. The speaker cables are a pathway between the speaker and the amplifier, sending audio signals. 

The terminals are two in quantity, one is called the input from which the audio  signals are sent, and the other one is the output which is connected to the amplifier for the amplification of the sound. One terminal is positive, and the other one is negative. 

The terminals are total in 4 coloured connections. Some airports can be bi-wired as red and black. 

Speaker Wires

The wires are the main character when it comes to connecting the speaker and stereo amplifier. Speaker wires are the ones responsible for connectivity. Most of the time, the speaker wire are coloured to avoid confusion between input and output. Speaker wires consist of the negative & positive terminals. Both comprise a marker that differentiates between the positive and the negative. 

After connecting wires to the speakers, the speaker wire need to be stripped, which helps in revealing the elements. After that, twisting is needed for both strands to act as one. There are other speaker versions where it is easy for the owner to connect them. Speaker wires consist of positive and negative terminals, which, when attached incorrectly, can prove very bad. So double-checking can be good. 

Steps to Connect Your Speaker to Amplifier

After learning the basics, it is now easy to install the speakers. To avoid damages like electrocution, make sure that the amplifier is unplugged. 

  • The corresponding wire at the back of the amplifier needs to be connected to the end of the speaker. Keep a check on terminals. Just in case it requires a spring slip terminal before installing the wire, remember to push it down. 
  • Attach the wire to the speaker. If it is a binding spot, lose the screw before installing the wire into the post. Negative and positive terminal connectivity is necessary, as if not attached properly, it can cause sound disturbances. 
  • If both the speaker and the amplifier are connected perfectly, the amplifier is now ready to be plugged in, and you can enjoy the speakers’ sound. 

Understanding Gauge

A lesser number of gauges means that the thickness of the wire is more, and you are indeed getting very high-quality sounds. This is because resistance is lower to the flow of current, which is represented by a thicker wire. The wire thickness is readily available and can be chosen in many ways. 

If the speakers in your house have a height that is around 50 feet away from the place of the amplifiers, 16 gauge wire will be perfect for transmitting good-quality sound. If the speakers have a low impedance of around 4 or 6ohms, and the amplifier is distant as 50 feet, a wire to the thickness of 10 to 14 gauge will do the work just fine. 

Wires are the ones from which the power or current flows from terminal to terminal. Wires are used for connectivity. The energy passes through them in the form of input and output. The information is turning on the switch and transferring the power amplifiers from the speakers. The outcome is the intensified sound from the amplifiers. 

Wire You Would Need Between the Amp & the Speakers

The distance between the amplifier and the speaker will determine the length of the wire that will be needed. A string piece’s one side is put at the end of the speaker and the other at the end of the amplifier. After that, take a measure of that string with a measuring tape. 

After that, finally, it is time to connect both of them together.

Before connecting both of them, make sure that the amplifier is turned off to avoid any electrocution or any other damage that can be done to the speakers. Choosing the correct type of wire can also prove suitable for the speakers and the amplifiers. This process needs to go through to avoid future problems. After that, choose the correct terminals (negative and positive).


The conclusion is that connecting the speakers to amplifiers is not as easy as it seems. There are many dangerous things that, when overlooked, can cause a significant malfunction. Speakers need speaker wires and terminals to fulfil the requirement of being connected to the speakers. Amplifiers are used to enhance the sound quality for a better version of music.
