How To Connect Speakers to Receiver with Wire

A cable used to connect amplifiers to speakers is known as speaker wire. The audio is amplified and sent to the speakers via this cable. It has a copper core that can be stranded or solid, as well as a PVC jacket that protects the core from interference and other external influences. This blog is for those people who online often ask how to connect speakers to receiver with wire.

The core is usually stranded, which means it’s made up of a collection of tiny wires that are twisted together to make a larger (thicker) conductor. There are a couple of reasons behind this. For starters, a solid conductor makes the wire far less flexible, making installation more difficult. More importantly, solid conductors have a greater skin effect, which increases resistance and power losses, both of which we want to minimize.

Your audio system’s speakers each require their own electrical signal. This signal is sent to the amp or receiver by connecting speaker wires, therefore you’ll need a separate cable for each one. Two-wire stereo cables, consisting of two copper wires, are required for all speakers except the subwoofer. For the subwoofer, a mono stereo cable will suffice. Only the ends of all types of wires are visible due to a synthetic coating. To get the know-how to connect speakers to receiver with wire, we must consider speakers terminals connections.

Terminals of the speaker

Speaker cables are connected to terminals on the back of most stereo receivers, amplifiers, and conventional speakers. Spring clips or binding posts are the two types of terminals available.

For simple identification, these terminals are almost always color-coded: the positive terminal (+) is usually red, while the negative terminal (-) is usually black. Some speakers are bi-wire capable, meaning the red and black terminals are sold in pairs for a total of four connections.



Most speaker cables are bare that’s why you’ll need a wire stripper to expose the strands at the ends. Whether your equipment uses spring clips or binding posts, tightly twist the bare wire strands so that they stay together as a clean single twisted wire.

Speaker wire comes with its own connectors, which might help with connections and polarity identification if they’re color-coded. Plus, if you don’t enjoy fiddling with naked wires, you can attach your own connectors. Only spring clip terminals are utilized with pin connectors. These pins are sturdy and simple to use. Binding posts are only used with banana plug and spade connections. When you tighten the post, the banana plug goes straight into the connector hole, while the spade connector stays put.

Things to know before connecting the speakers with wire properly

Connect the receiver’s left speaker to the terminals specified on the right

If you plug the right side speakers into the jacks labeled for the left side, and vice versa – the left side speakers into the correct side jacks – you’ll get this type of misconnection. What will happen if this happens? It’s nothing to be concerned about. Sound that is supposed to come from one direction will come from the opposite direction. Often, you will be completely unaware of it. Of course, properly connecting the speakers is necessary to fully appreciate the efforts of the sound engineer who worked on what you’re listening to. A bad connection, on the other hand, will not hurt your equipment.

Connect the positive and negative terminals together.

Nothing will go wrong if you reverse the poles and connect the amplifier’s negative output to the positive input on the same speaker. It will function properly. The situation will be identical if you connect reverse poles for two speakers in the same way. If you connect two speakers in different ways, you’ll run into issues. This is what it’s called when you want to link speakers that are out of phase.

You should not be concerned about the equipment’s safety in this instance, but the sound quality will be unacceptable. The fact is that these speakers’ diaphragms will travel in opposite directions. The low-frequency waves will quiet each other as a result of this.

How To Connect Speakers to Receiver with Wire (Soldering) and crimp connectors?

Soldering wires

Solder wires are low-melting-point wires that can melt in tandem with the soldering iron. Soldering wires come in a variety of shapes and sizes, depending on the application and soldering temperature. There are two types of solder wires: lead alloy solder wire and lead-free solder wire. We can use the soldering wires to connect the speakers.

Crimp connectors

Crimp connectors, also known as crimps, are widely used in electrical work to securely link cables in fixed wiring installations, most commonly to terminate stranded wire. With a specialized instrument used to cold weld the crimp termination onto the wire, this is frequently faster, easier, and cleaner than soldering. Following illustration elaborates how to connect speakers to receiver with wire using solder and crimp connectors

Take the following steps to connect a speaker to an amplifier

  • Place the amplifier and speakers where they belong. Ensure that the connection panels are accessible.How-To-Connect-Speakers-To-Receiver-With-Wire-3
  • The wires should not obstruct your regular activities. There are numerous methods for securing and concealing cables. You can use duct tape or cover them under moldings on the wall, for example.
  • Connect the speaker cords to the amp’s appropriate outputs. In practice, the connections are indicated on the gadget, so it’s not too difficult. Connect the right-hand speakers to the receiver’s outputs with the appropriate labels. The situation is the same on the left side.
  • Also, make sure the poles are connected correctly. Make sure the cable’s positive pole is connected to both the positive pole of the speaker and the positive pole of the receiver. In the case of negative poles, you must do the same. This should be made easier by the color scheme and wire marking.
  • Open the receiver’s mounting to create a gap in which the stripped end of the cable can fit.
  • Close the receiver after carefully inserting the cable’s end into the connector.How-To-Connect-Speakers-To-Receiver-With-Wire-4

How To Connect Speakers to Receiver with Wire-Frequently Asked Questions

Is it possible to connect two speakers to a single channel?
If you wish to power two speakers with a single-channel amplifier, the first step is to figure out the amplifier’s output impedance and the impedance of your speakers. The amplifier’s output impedance should ideally match the impedance of the speakers. 

What is the maximum number of speakers that can be connected to a receiver?
For example, a receiver with nine sets of speaker outputs may only be able to power seven speakers at once. Consider a nine-channel receiver with eleven speaker outputs. A full nine-channel surround sound system, as well as stereo speakers in another room, can be connected.

What color speaker wires complement each other? Connect Speakers with Wire
The positive wire is usually red, whereas the ground, or negative is black. Most speaker wires, on the other hand, do not support color. The good news is that when it comes to speakers, it doesn’t really matter which one you choose as your positive and which one you choose as your negative as long as you’re consistent.

How do you connect four speakers to a single-channel amplifier?
A 4 zone speaker selector switch is the simplest and safest way to connect four pairs of HiFi speakers. Simply run a wire from the central location (lounge area) to each speaker to complete the wiring. To avoid amplifier overload, the box should also take care of any impedance matching.

Is it louder to have speakers in series or parallel?
To answer this topic, parallel speakers are often louder than series speakers because of the following: When you connect speakers in series, the total speaker impedance (Ohms) load rises, limiting the amount of electrical current (amps) that can travel through. As a result, the power output of the amplifier or stereo will be reduced.

What happens if the positive and negative speaker wires are mixed up?
When two identical signals with reversed polarity are combined together, the signals cancel out. One wave is positive in this scenario, while the other is negative, and vice versa. As a result, there is silence. Destructive interference is the term for this.

Which of the speaker wires is connected to Red?
The positive wire is usually red, whereas the ground, or negative is black. Most speaker wires, on the other hand, do not support color. The good news is that when it comes to speakers, it doesn’t really matter which one you choose as your positive and which one you choose as your negative as long as you’re consistent.

What happens if speaker cables are crossed?
What happens if the speakers are connected in the wrong direction? Speakers that are wired backward are out of phase. Phase cancellation reduces the output frequency of specific frequencies, which degrades the audio quality. It also has a negative impact on the speakers’ stereo imaging.

What is the positive side of a speaker?
When the speaker is facing up, the positive terminal is normally on the left side. 

Is it positive black or white speaker wire?
Red (positive), Black (negative), White or Yellow (positive), and Green (negative) are the color designations for the four-conductor cable for speaker one (negative)
