At times, choosing the best amplifier can be a challenge especially when it comes to selecting the perfect one for your speaker. Are you stuck with the thoughts of getting a new amplifier or you are probably looking for how to choose the best amplifier for your speaker?

There are a lot of things to consider when choosing the right and perfect amplifier for your speaker, trust us, we have been in your shoes.  We know this process can be a little tricky. That is why we are doing you a favour by creating this guide to put you through when choosing the best amplifier for your speaker.

Things to Take into Consideration When Choosing an Amplifier

  1. The power output
  2. The Total Harmonic Distortion + Noise
  3. Input connections
  4. The Crosstalks
  5. The Signal to Noise Ratio

The power output

To choose an amplifier, the first thing you take into consideration is its power output. This is because it determines how loud the music sound can be. Typically, 100W is loud enough to set most parties on fire while 10W is suitable for average listening. Ensure you know your speaker power ratings (Watt, ohms or impedance) as it will aid you in choosing the best amplifier for your speaker.

The Total Harmonic Distortion + Noise

The effect the amplifier has on sound output is measured by the total harmonic distortion + noise. The more the distortion, the more the sounds colouration. If the distortion rate is low, the output of the amplifier sound will be closer to the original recording. One of the things you also need do is to get the speakers that suit your listening preference.

Input connections

When selecting an amplifier, you need to be sure that it has enough inputs for all the things you would love to plug in. Do not forget that there are various types of inputs like USB for home theatre and laptops, phono for turntables and 3.5mm for iPods. Having all the input has advantages but if you are stuck with only a few option, go for the one that has the type of the input you need or one that produces the best sound quality.

The Crosstalk

The unwanted mixture of left signal and the right output is called crosstalk. We really do not want that because the more the crosstalk, the more difficult it is to pick out the position of your instrument.  When it comes to crosstalks, look out for the number after the minus sign. The higher this number, the more the stereo separation. Knowing this will guide your choice of amplifier.

The signal to Noise Ratio

There is always a little amount of noise from the electrons In the amplifier. Getting an amplifier that will make the background noise as inaudible as possible should be your goal while selecting an amplifier to ensure you hear more of the wanted sounds and less of the noise. Opt for an amplifier that has a good signal to noise ratio.

How to Choose an Amplifier for Your Speaker

If you want to use an amplifier for your speakers, you need to take the following factors consideration.

  • Channel Compatibility
  • Power Compatibility
  • Amplifier and head unit Compatibility

Channel Compatibility

There are many different configurations of amplifiers. Firstly, you need to consider the number of speakers you have. The number of the speakers in your sound system will determine the number of channels your amplifier should have. Typically, you will require a channel for each speaker you want to amplify. Should you want to amplify two speakers you need a 2- channel amplifier or you bridge the two to run a single sub.

When you select an amplifier, make sure you select the one that has the right amount of channels to connect all your speakers and provide you the unique sound you desire.

Power Compatibility

You should be careful to avoid overpowering your speakers to avoid getting undesirable results. To avoid this, you need an amplifier that matches your speaker power ratings. If your amplifier is not compatible with your speaker power demands, the end result isn’t always good. Ensure that the amplifier can function well with your speaker power capacity before you go for it.

 Amplifier and Head Unit Compatibility

Get an amp that has your speakers level inputs if your speaker units do not have preamp outputs.  This way, you will get a very clear sound and prevent the possible issues that may arise with the adapters and wires.
