How to Connect Speakers to Amplifiers

Similarly to speakers, amplifiers are a key component of a stereo system. In most cases, the amplifier is the device that turns received sound into an audible signal that could be heard by both the speaker and listener.

The push-pull function of this device causes it to produce harmful electromagnetic radiation(EMR) in the proximity of other devices. This radiation can cause physical damage to your health and also affect your hearing if you’re not careful about doing these things correctly.

6 Ways of Connecting Speakers to Amplifiers:

1. SPK-HConnector

The first way to connect speakers to amplifiers is through using an SPK-H connector. This is a mating adapter that you insert into the outlet on your amplifier, which then turns the speaker’s output signal into an audible sound report.

This system provides better signal integrity because it will not allow any other component to use your audio input source. The SPK-H connector set comes with various types of jacks that are designed for both 4-pin and 8-pin audio connectors.

This eliminates potential quality issues between different kinds of connectors by using only one connector for all kinds of audio inputs.

Although this connection method is very effective, it can only be used for low-power speakers and amplifiers.

2. Grounded Y-Cables

Another way to connect speakers to amplifiers is through using a ground cable for the two devices. This type of cable resembles a power cable and has a series of audio connectors on either end that are connected with stranded wire.

If you are using this type of setup, you will need to connect the black wire of your speaker (4-ohm to 2-ohm) output with the power wire of your amplifier in order to prevent any damage from occurring in the audio signal path.

This type of connection will also prevent your amplifier from receiving any noise from the speaker’s power source or from giving out any unwanted radio transmissions..

3. Subwoofer Cable

In most cases, a subwoofer cable is a simple device that allows you to connect a speaker directly to an amplifier. The only thing that you need to do is connect the speaker’s larger-diameter wire with the power wire of your amplifier while connecting the smaller-diameter wire with your audio input source.

And since this type of connection method meets all of the standards sold in U.S., Europe and Australia, it is very popular among audiophiles everywhere.

4. RCA Cable

An RCA (or phono) cable is a flexible audio patch cord that is commonly used in home entertainment systems and low-cost audio equipment. This type of connection system uses plastic plugs and jack connectors on both ends, one of which has a red (+) and white (–) line while the other has a red (L) and white (R) connector.

These cables can carry two channels of stereo audio signal, which means that they can connect only two devices at the same time. If you want to connect more than one speaker set, you will need to use more than one RCA cable for each speaker set.

5. Speaker Terminals

This method of connecting speakers via wire to amplifiers has become very popular among professional audiophiles. The speaker terminals are designed for speakers with dual binding posts, which accept single banana plugs or bare wire connections.

You should connect the positive terminal of your speaker to the red (+) line of your amplifier’s output while connecting the negative terminal of your speaker to the black (–) line of your amplifier’s output. If you use bare wires, then you should connect them directly into their respective terminals without using any other tools or equipment.

6. Power Distribution Center

For most home entertainment systems, the power distribution center is a great alternative to all of the other connection methods mentioned above. This device allows you to control power distribution to every other component in your system, which then eliminates the need for any other power cords or adapters.

This type of connection method also makes your system easier to install because it only uses one cable to connect every single component in your system. Some power distribution centers also have built-in filters that eliminate radio transmissions and noise from any external source, which ensure the cleanest possible sound quality.


In most cases, the amplifier is one of the most important components of a stereo system. If you want to connect your speakers or subwoofers to your amplifier for safety reasons, then it’s important to be sure that all safety standards are being met by each component.

In most systems, the speaker terminals use a female XLR connector that accepts a male XLR connector on a speaker terminal strip. The power distribution center uses a male BNC connector on the back of the unit while RCA cables use male RCA connectors on both ends.


Q: How to wire four speakers to one amplifier?

A: There are two ways to wire four speakers to a two channel amplifier: in series or in parallel. Which one to choose depends on both the speakers and the amplifier, specifically their impedance levels and limits.

Q: What is the best amplifier for speakers?

A: McGary Audio SA-1 ($3,985 USD) First Watt SIT-3 ($4,000 USD) Audio Hungary Qualiton APX 200 ($4,700 USD) Merrill Audio Thor monoblock amplifier ($4,800 USD) Odyssey Audio Kismet ($4,900 pair USD) Pass Labs XA25 ($4,900 USD) Linear Tube Audio ZOTL40 ($6,800 USD) McGary Audio SA-2 ($7,985 USD) Manley Labs Snapper monoblocks ($8,400 pair USD)

Q: How to connect speakers using speaker wire?

A: – Use a knife or wire strippers to strip away a half-inch from the ends of each wire. – Twist the copper wire ends to eliminate any loose strands. – Unscrew each banana plug cap and thread it onto each wire. – Insert the bare wire into the plug’s hole and screw it securely. – Screw the cap back onto the plug.

Q: How to properly Power Your Speakers?

A: Make sure your amplifier can handle your speaker’s impedance. Check the spec sheets and match up your speaker to the matching amp channel. Buy an amplifier that suits your power needs. … Triple check your impedance math when connecting speakers in serial or parallel. Avoid cable snake oil,stick with what’s in the box.
