Simple Instructions For Connecting Amplifier to Speaker

It may appear complex to connect an amplifier to a speaker, but it is actually rather simple. This post will provide you with Simple Instructions For Connecting Amplifier to Speaker step by step through the procedure. This guide helps ensure that you get the finest possible sound from your audio equipment, whether you’re constructing a new sound system or simply connecting a speaker to an existing amplifier.

1. The Amplifier connection ports

To ensure proper sound quality and protection, you must carefully and thoroughly learn the connection ports as well as the symbols on the amplifier before connecting the speakers to the amplifier. Maintain the equipment in excellent condition.

If you do not properly learn before connecting to other devices through each connection port on the amplifier, unexpected faults will occur during use.

Amplifier connection ports

You must be aware of the following connecting ports on the amplifier in order to connect the amplifier to speaker:

  • Playback: The port connects to the Audio OUT signals found near the receiver.
  • Rec: The port that connects to the Audio IN audio signal on the receiver.
  • CD: CD/VCD and DVD player connection port…
  • Speaker Systems: The port is directly connected to the speaker in speaker systems.
  • Tuner: A gateway for radio connections.
  • Phono: Large phonograph connector.
  • Recorder: A recorder is a port that allows you to connect to recording devices.
  • Line: A port for connecting to external audio sources such as televisions, MP3 players, and so on.

2. Notes to keep in mind before connecting speaker to amplifier

Before connecting a speaker to an amplifier, keep the following impedance and power considerations in mind:


Check that the impedance of the speaker matches or falls within the range specified by the amplifier. Impedance is measured in ohms. Using speakers with a lower impedance than the amplifier may cause the amplifier to overheat, potentially causing damage to both the amplifier and the speakers. Higher impedance speakers may produce poor sound quality.

Speaker power

Check the power handling capabilities of the speakers to ensure they can handle the power output of the amplifier. Watts (W) are the highest amount of power that a speaker can withstand without being destroyed. Using speakers that have a lower power handling capacity than the amplifier’s output can damage the speakers, whereas using speakers that have a higher power handling capacity than the amplifier’s output will not harm the amplifier but may result in poor sound quality.

Select speakers that are matched to the amplifier for maximum performance and sound quality. Many amplifiers and speakers are designed to work together and are sold as a pair. If you are unsure whether your equipment is compatible, consult the manufacturer’s specifications or seek professional assistance.

Keep the following other considerations in mind when connecting speakers to an amplifier:

  • Check the polarity of the speaker wires before connecting them. Positive and negative terminals on both the amplifier and the speakers should be matched.
  • Make sure the amplifier and speakers are both turned off before connecting them.
  • Use high-quality speaker cables that are long enough to reach the amplifier but not too tight or loose.
  • Avoid placing speakers too close to walls or corners, as this may cause acoustic problems and distortions.
  • Keep the volume level in mind when testing your setup. To avoid hurting your equipment or hearing, start with a low level and gradually increase it.

By remembering these points, you can ensure a proper and safe connection between your amplifier and speakers, as well as the best sound quality possible.

3. Connecting Speakers to an Amplifier

Step 1: Locate the connecting ports for the speaker and amplifier

The first and most important step in connecting the amplifier to the speaker is to identify the speaker and amplifier connection ports.

When you look at the amplifier, you will notice that the connection port is divided into two stations, denoted A and B, with four connection ports for negative (black) and positive (color) signals in each station.

How to wire your speakers to your amplifier

As a result, four-speaker wires will be connected to each station, two on the left and two on the right.

If only two speakers are available, connect at station A. Pay attention to the wire colours and symbols on the amplifier and speakers during the connecting process to ensure a proper connection.

Step 2: Connect the amplifier to the speaker

You can connect the speaker to the amplifier using either an HDMI or AV cable.

Connecting speakers to an amplifier with an HDMI cable:

Examine your amplifier and speakers to check whether they have HDMI ports to receive audio signals. Some HDMI ports allow just video signals, while others accept only audio signals.

Connect one end of the HDMI cable to the HDMI output connector on your amplifier and the other end to the HDMI input port on your TV.

Turn on your television and select HDMI as the audio output.

Examine the sound from your speakers.

Connecting speakers to an amplifier with an AV cable:

Check to see if your amplifier and speakers have audio-capable AV connections. Colour-coded AV cables are common, with red and white plugs denoting the right and left audio channels.

Connect one end of the AV cable to the audio output ports of your amplifier and the other end to the audio input ports of your TV.

Turn on your TV and switch the audio output to the AV input.

Examine the sound from your speakers.

Step 3: After connecting, listen to the sound quality

After connecting the amplifier and the speaker, you will perform a sound quality test by lowering the volume and gradually increasing it to hear the final sound. Is the connection as good as it should be?

Keep the following principles in mind when connecting the speakers to the amp:

  • Read the connecting ports and symbols on the amplifier and speakers carefully to ensure a proper connection.
  • When making a connection, connect the negative pole first, followed by the positive pole; otherwise, the device will be damaged.
  • To avoid equipment explosion, use equal-impedance amplifiers and speakers to conduct the connection.
  • Select and use high-quality speaker wire to improve the sound after the connection while avoiding interference with the transmission line.
  • Place the left or right speaker wherever you want, regardless of where the amp is.
