What are banana plugs, spades, binding posts & spring clips? Learn how to connect speaker wire to your system & identify the different types of connections. If you are wondering how to connect speaker wire to your stereo or home theater system, then you’ve come to the right place. It’s not the most exciting part of setting up your equipment – but without a speaker wire, you won’t hear anything! Before you begin, it may seem like a tricky business. But, once you give it some thought, it is quite straightforward. First, you need to understand the different connection types that you might have on your gear. Then, you can think about the best way to connect the wire. Table of Contents Show
How Do You Connect Speakers with Speaker Wire?Speaker wire is made of two separate cables that need to be connected to the positive and negative connectors on the amplifier and speaker. It doesn’t matter which way round you connect the wires – even if the wire is marked with a plus and a minus. Just make sure that the same piece of wire is connecting the positive and negative terminals on the amplifier and speaker. Below you can see the binding posts on the rear of an AV receiver. There are two posts for each speaker. They are clearly labeled as positive and negative. The convention is to color the positive side red and the negative side black. But they may not always be color-coded. One wire, like the one pictured above, will connect to the positive and negative posts for a single speaker output. The other end of the wire will connect to the speaker. Binding posts on the rear of an AV receiverRemember, the positive connection on the amplifier must be connected to the positive connection on the speaker. The same with the negative connections. What Happens if You Reverse Speaker Wire?First, it depends on what you mean by reverse. There are a couple of ways you might do this. 1. Connect Stereo Speakers to the Wrong ChannelsIf you connect the left speaker to the terminals marked right on the amplifier – and the right speaker to the terminals marked left on the amplifier. What would happen? Nothing. Except, the sound engineer who mixed the album would be annoyed. Because the drum kit would be the ‘wrong way round’. Anything which was designed to be heard on the left would appear on the right – and vice versa. Nobody would care apart from the artist who spent 6 months getting everything just right. 2. Connect the Negative to the Positive TerminalsIf, for a single speaker channel, you connect the amplifier’s negative terminal to the positive connection on the speaker – and the amplifier’s positive terminal to the negative connection on the speaker. What would happen? For a single speaker, nothing would happen. It would work just fine. If you had two speakers, and they were both wired the same – again, it would be fine. If there were two speakers, and they were wired differently, then this is what is known as wiring the speakers out of phase. The diaphragm in one speaker would move out, while in the other speaker, it would be moving inwards. It’s hard to explain what this sounds like, but it just sounds odd. It will appear thin and lacking in body. What is happening is that some of the lower frequencies will cancel each other out as the sound waves move away from the speaker. So, you won’t break anything, but it just won’t sound right. You’ll probably notice it if you’ve done it, but it’s always good to double-check your wiring. Some AV receivers will try and detect any speakers that are wired out of phase when you run the automatic room setup. Although, they don’t always get it right. If you are interested, this is an excellent video demonstrating why you need to connect your speakers in phase: What Are the Different Types of Speaker Wire Connections?The first thing you want to do is look at the connections on your speakers and amplifier. This will determine how you can connect the speaker wire. There are two main types of connections that you will encounter. Just be aware that you may have one type on the amplifier and a different one on the speaker. 1. Binding PostsBinding posts are found on all kinds of amplifiers and speakers – from budget models to high-end equipment. They are the most common type that you will come across. Surround left and right binding posts on an AV receiverThere are often two ways of connecting the speaker wire to these:
So, for this type of connection, you can use bare wire – or connect spades or banana plugs to the end of the speaker wire. Speakers that have binding posts might not have an opening at the end to insert a banana plug. Some do, but it’s more common on amplifiers. A binding post on a speaker will often look like this: So, with his connection, you can either insert bare wire into the hole – and then tighten the screw. Or, use a spade connection and place it around the post before tightening it up. 2. Spring ClipsSpring clips are more common on budget amplifiers and speakers – and all-in-one systems. However, they can be found in all types of equipment. Connecting speaker wire to a spring clip connectorAll you need to do is push the bottom part of the clip and push the speaker wire into the hole above. You can use bare wire or pin connectors with this type of connection. Speaker Wire Termination TypesNow that you know what type of connections you have for your speaker wire, you can make the final choice on how to terminate the ends. By the way, take a look at the speaker wire 101 if you want to figure out which is the best gauge speaker wire for your system. Attaching a connector to the end of a length of speaker wire is known as terminating the wire. However, the first option doesn’t require any connector at all. Connecting Speakers with Bare WireAll connection types will accept bare speaker wire. This is the easiest method as you don’t need any extra accessories. All you need to do is:
If using bare wire is the easiest way for you to achieve your goal, then go with it. Don’t lose any sleep over this. However, attaching connectors can have advantages. Terminating Speaker Wire with Banana PlugsBanana plugs are my favorite way of connecting speaker wires. You will need to buy these as a separate accessory to your wire. You will need four banana plugs per wire – two for each end of the cable. Of course, that is assuming that you will be using banana plugs for both the amplifier and speaker. You might not want to – or be able to. Banana plugs may attach to the cable in different ways. Many come with screw-in connections that just need to be secured to the cable with a small screwdriver, which is one of the easiest methods. Some are self-crimping which just means that they will clamp the cable when you tighten the cap of the plug. Others may need soldering. So only choose this type if you are prepared to break out a soldering iron. The general procedure for connecting screw clamp banana plugs to speaker wire is:
Each plug can then be inserted into the end of each binding post. It’s easy to forget to thread the cap onto the cable before securing the plug to the wire, meaning you have to undo it all again! After doing this a couple of times, you’ll usually start to remember! You may find some banana plugs that connect to the wire in a slightly different way to this, but the general idea is the same. You won’t appreciate how much easier banana plugs are to work with until you are crawling around the back of an amplifier trying to attach the bare wire to a binding post. Popular Banana Plugs Mediabridge 24K Gold-Plated Banana Plugs What Is It: A robust banana plug for connecting to the ends of speaker wire - which makes wiring your system easier. Pros:
Cons:
Some people like to solder the wire to the plug to create a more robust connection – even if it is a screw-in model. You can if you wish, but you don’t have to. Banana plugs that come with screw-in connections work perfectly well without soldering as long as you are careful when you join them together. However, there is a chance that they might loosen over time, so you might need to check the connection if you reconnect them regularly. Many banana plugs will have a female connection on the bottom end – like the ones pictured above. This allows you to plug another banana plug into it. This is useful if you need to connect multiple speakers to the same terminal. You won’t often need to do this, but sometimes it can be helpful. For example, if you need to feed a high-level subwoofer input from the front left and right speaker terminals. Banana plugs pins are a standard 4mm in diameter, which is just right to fit into the end of a binding post. Using Spade Connectors with Speaker WireSpades are an alternative way to terminate your speaker wire. As with banana plugs, if you are using spades at both ends, you will need four spade connectors for each wire. The spade connector can either be angled or straight. It shouldn’t matter too much which one you buy. But, in some circumstances, one may be easier to fit than the other. They usually connect to the speaker wire by crimping, soldering or by a screw connection like with banana plugs. Crimping is where you use a tool to bend the connector’s end so that it clasps tightly to the wire, and it can be a good solution if you don’t want to get involved in soldering the wire. It’s always best to use a proper crimping tool to make the join. Although it’s tempting just to grab a pair of pliers, you won’t get the same tight connection. Done properly, a spade-crimped connection shouldn’t need soldering. Once you have the spades attached to the wire, you need to unscrew each binding post and push them into place. They will be very secure once you tighten the cap again. This is preferable to using bare wire as you can be sure of a tight and reliable connection.

Cons:
Spade connectors can be ideal when you are attaching a wire to speakers that are installed very close to a wall. In that case, you may not have enough room to use banana plugs. So, if you don’t want to use bare wire, spade connectors will connect at a 45 or 90-degree angle allowing the wire to drop straight down. Terminating Speaker Wire with Pin ConnectorsPin connectors are like a smaller version of a banana plug. In fact, in some cases, you might see them referred to as banana plugs. They come with pins that are generally about 2mm in diameter. The pin is either straight, or you can get them with angled pins. Like spades and banana plugs, you need to strip some insulation from the wire and attach the pins to the bare wire. Crimping or soldering is often used to connect these to the wire. However, like the pin connectors in the picture above, they may also have a screw-in connection. Just undo the screw a little, insert the bare wire, and then tighten the screw again. Then, make sure you have a firm connection by gently pulling the speaker wire. This type of speaker wire termination is generally used for spring clip connections. Simply push down the clip and insert the pin into the hole.

Cons:
You could also use them with binding posts by inserting them through the central hole in the post – and then tightening the cap. But it’s not the usual way of using this type of connector. Using pin connectors is a cleaner method than using bare wire and increases the chances of a solid connection. Connecting the Wires to Your Amplifier and SpeakersOnce you have your speaker cable terminations ready, you just need to connect the wires to your amplifier and speakers. A stereo amplifier and speakers will connect like this: Connecting an amplifier and speakers with wireJust make sure that you connect the amplifier output marked speaker left to the left speaker – and the output marked speaker right to the right speaker. Also, the same end of the wire must connect to the positive terminal at the amplifier and speaker – and the same for the negative terminals. The speaker wire is usually marked in some way so that you know which is the same wire at each end. A multichannel AV receiver is a little more complicated as it has more speaker terminals. However, the concept for home theater wiring is the same as with a stereo amplifier. You just need to make sure that you connect each output terminal to the correct speaker. So:
If you have a 7.1 speaker layout or are using Dolby Atmos speakers, you will have even more speakers to connect. But it’s the same procedure, just take your time and make sure you get it right the first time. When you run the auto room configuration on your AV receiver, it will send a test signal to each speaker. So, you will soon find out if you connected the correct speakers to the rear of the amplifier. If not, no problem. Just unplug it from the amplifier and try again. ConclusionWere you confused by the thought of connecting speaker wire to your amplifier and speakers? If so, hopefully, you’ve found the answers to your questions. It’s not too complicated when you get into the details, but it can seem confusing until you understand the different choices that you have. The connections that you have on your amplifier and speakers are the first thing to consider. Once you know this, you can make the best choice for terminating the speaker wire. You can take the easy route and just use bare wire – or choose to attach banana plugs, spades or pins. There isn’t a wrong way. Just go with what seems to make sense for your system.

Is red positive or negative on speaker wire?The color codes for the four-conductor wire for speaker one are Red (positive), Black (negative), and White or Yellow (positive), Green (negative).
How do you connect red and black speaker wires?For spring clip terminals, press down on the red (positive) or black (negative) clips and insert the speaker wire into the slot. Then, release the clips.. For binding post terminals, loosen the red (positive) or black (negative) binding posts by turning them counter-clockwise.. Where does the red and black wire go speaker?The convention is to color the positive side red and the negative side black. But they may not always be color-coded. One wire, like the one pictured above, will connect to the positive and negative posts for a single speaker output. The other end of the wire will connect to the speaker.
What happens if you mix up red and black speaker wire?They will operate out of phase with one another. That translates to a sound being created by the opposite mechanical motion of the magnet of the speaker. So when it's supposed to be moving forward, it's moving backward. The result is a muddled sound.
