What to look for as you purchase the best power amplifiers in the world

Since the amp is the most important element in the treatment of the signals transmitted by the sound system, it calls for much sensitivity during its purchase. To guarantee the acquisition of a perfect power amp for your desires, you have to put several aspects into consideration.

The key objective of this buying guide is to walk you through all these aspects before you purchase one and hence avoid the intimidation experienced while buying one due to the incorporation of many features into the amps. The following specifications will make a key difference to the sound you hear:

Power output

Power output is directly proportional to the loudness of the music produced by the speakers. As the size of the speakers increases, the power needed increases and more loud sound is produced. You should choose an amplifier whose power output is roughly 10W as this will be averagely loud enough and you will not end up interrupting your neighbors' environment. Ensure you check the sensitivity of the speaker as this will play a great role in the quality of sound produced.

Signal to noise ratio (SNR)

Many are the times you notice the production of some unwanted background sound while an amplifier is operating. It occurs as a result of electrons whizzing around inside. This noise tends to conflict with the music been played. You should therefore choose an amp whose background noise is imperceptible to ensure that less of the noise is produced. This is measured using the signal-to-noise ratio. You should select one with bigger numbers, that is, the background noise ratio is higher than the sound.

Total Harmonic Distortion + Noise (THD+N)

This is defined as the metric of how much distortion the amplifier causes to the final sound output produced by the speakers. Generally, the higher the distortion, the lower the quality of sound produced. On the other hand, the lower the distortion, the more improved the sound will be and will be almost a resemblance to the one of the original recording. As you buy, it is advisable to go for the amplifier whose total harmonic distortion plus noise is low or rather minimal. Besides, the speakers also contribute immensely to the quality of sound produced and you, therefore, ought to purchase one which matches the quality of your amp.

Inputs and connections

For your amp to work efficiently, you must connect it correctly and with the right cables. You should ensure that every cable matches the right input. Besides, you ought to have enough inputs sufficient for everything you intend to the plugin. In absence of the right cable, ensure you select one which produces the best quality sound. As you purchase your amp, ensure you identify the right cables suitable to give you the best listening experience you crave for.

Frequency response 

Check for the manufacturer's indicator of the amplifier's frequency response. This will enable you to understand the relationship that exists between the input and output signal levels for the amp you intend to purchase. In most scenarios, this is indicated by the aid of a graph or even figures which show the frequency range the amp is designed to operate at. When the graph is flatter, the amplifier quality will be high. The best range for the audible spectrum usually lies between 20 and 20000Hz.


This usually shows the relationship that exists between the output power and the input power of the signal. It is usually measured in decibels (dB)

Frequently Asked Questions:

Does a car amplifier improve sound quality?

The major work of an amplifier is to improve the quality of sound. A car amplifier overcomes road noise and allows travelers to enjoy the music. The music intelligibility and clarity are improved by an amplifier without any form of distortion.

They are the best devices to bring excitement and joy while driving on high-traffic roads. An equalizer and an amplifier are the tools for achieving thumping bass and ultra-high, fidelity sound for your car audio system. It gives more power to the subs and enables them to perform optimally.

They work extremely well for bass enthusiasts. They provide for the best music enjoyment and you cannot compare the two sub-optimal sound quality that does not use amplifiers. Listening to clean music with accurate high frequencies while riding a car is very refreshing.

You must have an amplifier for better sound in your car, no matter how small your audio system is. You do not have to be a bass enthusiast to use it but cool music gets enjoyable when streamlined by an amplifier.

An amplifier is an ideal device to take the low-level audio output from a source device and increases the output to a power that is high enough for driving speakers. Power amplification allows you to enjoy loud and clear music. With such kind of a sound, you can ignore the noise made by other motorists and vehicles on the road and drive peacefully.

You can opt to use inbuilt amplifiers inside the chassis of the car stereo or go for the external ones that you can place under the seat or in the rear side panel. They eradicate all sound distortions and eliminate any breakdown in sound quality.

What happens if an amplifier is too powerful than speakers?

Most speakers will get damaged through clipping. This mostly happens when you use an underpowered amplifier. Having a more powerful amplifier than a speaker seems to cause no harm as long as you keep the volume in check. At higher volumes, it looks like the power will blow up the speakers but that rarely happens.

 The speakers cannot blow up but they can get permanently damaged if you run them at extremely high volumes for too long. It can also cause noise pollution and damage the eardrums. A 1-watt amplifier can power a speaker as easily as a 1oo watt amplifier without any complications.

Speakers often have a sensitivity rating of about 86b decibels going upwards. There is some minimum power handling before the speaker distorts the amplifier. A speaker with a high impedance will require less current to power it than a speaker with a low impedance. Large power amplifiers are better and will help the speaker cope with large transients and dynamics.

This is unlike small amplifiers that will often struggle at high volumes. Big amplifiers have been used for home theatre systems that contain multiple drivers and inefficient home cinema speakers. They generate huge amounts of current to power the speakers but no damage occurs from them being too powerful.

The only risk of speaker damage is at high volume levels. When you use your speakers at considerable volumes, no damage can occur to your speakers. They will function optimally with the normal sound output. Speakers with too powerful amplifiers will often make the speakers struggle if they are connected with a continuous power rating.

The speaker is unable to distribute the heat energy from the amplifier and it will burn off the speaker's voice coil. Always check the maximum power handling described for both the amplifier and the speaker. Ensure the speaker observes twice the amount of power the amplifier carries. Also do not forget to keep your volume at considerable levels and avoid putting it to the maximum since the speakers can get damaged.
