How to match speakers and amps? Just like bread and butter, speakers and amps go together.

You need an amplifier to get the most of your speakers; however, that does not mean your speakers won’t work without an external amplifier.

Mainly, a speaker comes ready; so, once connected to a system that outputs audio, it’d playback any sound from the system, regardless of where an external amplifier is introduced in the connection.

An amplifier comes in handy when you want to hear your speakers sound better. With the help of an amplifier, your speakers would sound louder, clearer, and generally better.


But, in choosing amplifiers, you need to choose carefully. Certain types of speakers are only compatible with certain types of amplifiers.

Nevertheless, all types of amplifiers are basically designed to work with any type of speaker. But in the bid to get better sound production, audiophiles try to match speakers and amplifiers with the factors being discussed below.

How to Match Speakers and Amps?

It is thoughtful to consider these factors when choosing an amplifier you should use with your speakers.

1. Impedance

Talking about impedance, this is the main thing to look out for when pairing speakers with amps. So, what is impedance and how do you know the impedance of a speaker or amplifier?

In every speaker’s manual or specs sheet, the impedance is typically represented with the letter “I.” However, in some specs sheets, it is written in full. Impedance simply refers to the measure of electrical resistance of the speaker.

Similarly, on amplifiers, you’d clearly see the impedance rating on the manual or spec sheets. It is also the measure of the electrical resistance of the amp.

Impedance is represented with the “Ohms” symbol, “Ω.” For example, when you look at your speaker’s specs sheet, you may see something like 6Ω or 10Ω – that’s the impedance rating.

Now, how does the impedance rating of speakers and amplifiers affect their connectivity? Why should you be concerned about this factor when matching an amp with a speaker?

Speakers typically come with 4 – 8 ohms (Ω), while amplifiers can have up to 16Ω, which is about 2x what a speaker may carry.

Well, connecting a speaker with a 6Ω rating to an amplifier with a 10Ω rating would really cause any damage, but you may not get the best sound quality you wished for.

It is better if you connect your 6Ω speaker to a 6Ω amplifier or at most 8Ω amplifier. Furthermore, it is important to note that certain amplifiers output different watts into different ohms.

For example, an amplifier can output continuous 60W per channel into 8 ohms and 4 ohms, respectively.

However, this is mostly called Peak Power, which is the highest power of the amp. So, if the amp is pushed to its peak, it can deliver 80W into 8 ohms and 150W into 4 ohms.

Remember, it is important that you connect speakers with high impedance to an amplifier of high impedance, and low impedance speakers into an amplifier with low impedance.

2. Connectors

Here’s another important factor to consider – the connectors on your speaker and amplifier. You have to ensure that the speakers and the amplifier have the same type of connectors.

Connectors are the ports you can use to connect both the amplifier and the speakers; so, it is an important thing to look out for.
