What Is an Amplifier?

An amplifier is a device that is used to boost the power of an electric signal or wave, typically used for boosting the power of subwoofers and speakers.

Car amplifiers are categorised by the number of channels there are, like single channel amps, also called monoblock. These amplifiers are usually used to power the woofers.

Beside monoblocks there are multi-channeled amps, which depending on the number of channels, can “feed” 2, 3, 4, or more speakers.

Amplifiers are also separated by class. The classes are A, B, A/B, D. There are also G & H classes, but they are not officially recognised.

There are also other types of custom made amplifiers. Classes from A to D are in common use. These are the classes to consider when buying a car amp.

The function of amplifiers serves the amplification boosting of both power and quality.

Car Amp Buyers Quick Cheat Sheet

If you want to upgrade an existing amp or to install a brand new one, there are a few different factors that you should pay special attention to. It is like when making the perfect meal, all the ingredients must be carefully picked and measured. These are the three most important categories that you need to consider when buying an amplifier:

  1. Number of Channels
  2. Power of your choosing
  3. Quality of the powerful sound

If you want all that is listed in these 3 categories, then this next category is unavoidable:

  1. Compatibility with the audio system you have in your car (not just anything goes well with everything)

Besides the above mentioned, if you really want to avoid replacing some very expensive audio parts or components, you really need to learn your “stuff” about what to look for in terms of quality, class, and category.

Then you need to implement this into the audio amplifier that has exactly the power you need, number of channels, and of course compatibility with the rest of your car’s sound system. It doesn’t matter if you want to add power or quality or both to your stereos or subwoofer, you have to take into account all the important factors.

Be sure to match the output of the amplifier to the needed power of your speakers. Without enough power, you’ll get a distorted weak sound. In the case of an over-powered amp, you will “kill” or blowout your speakers.

Whether your speakers are factory built-in or you obtained new ones, you must know their Root Mean Square (RMS). The RMS of an amp has to be able to provide power from 75-150% of the speakers’ RMS. This way, you will cover that peak power the amp needs to provide to the speakers in short burst intervals.

Make sure to have all input/output cables, power equipment, all hardware, and cords.

The Story On All Channels

If you are the kind of driver that focuses his music in the cockpit without even turning on the backseat speakers, then you will be satisfied with a 2 channel amplifier or a 3-channel amp, one channel for the car subwoofer and the other two for the speakers.

You could keep your options open and take a 4-channel amp, two for each speaker and two channels bridged together for powering the sub. You can then use the amp for 4-speakers in the future.

There are 5-channel amps that will give your car the full treatment powering all four speakers and a subwoofer, if that is to your liking.

There are also amps with 6- or 8- channels, which is the best option yet. With this kind of an amp, you can also have a multiple active system for every speaker or double bridged car subwoofer or all that together.

The Full Power Mode

Usually the speakers that come with your new and beautiful car are powered by an amplifier that is good enough.

“Why then would I need another amp?” you might ask.

If you want more serious sound with greater performance, you will feel the need to add power and quality to the sound! Another thing is, if you are a driver who installed a subwoofer, in most cases you will need an external car audio amplifier.

The factory integrated amps have advanced over time, but still they usually offer smaller amplifiers that will offer you only 10 watts of power per channel. This is really not enough if we’re being honest. Due to the limited space on the dashboard, factory settings are not so bad, all things considered.

Again: if you install aftermarket speakers, you will need an external amplifier. Besides power, the quality of the bass depends on a good amp-woofer-speaker combo.

With Great Power Comes Great Quality

Many drivers today want exceptional quality in addition to power, so the need for an external amplifier comes with the means to have high power and quality of sound.

A good amplifier can provide you with clean sound free of background noise, which can occur from other components. It will also dial down the interference and distortion that can disturb pure sound.

An amplifier is the powerhouse that can create great sound quality on all volume levels while you tune into your favorite radio frequency. You don’t exactly need to be an audiophile to appreciate the crystal clear tweeters and a kicking bass.

Car Amplifier 101 – Terminology

You don’t want to play poker face with the seller when you go to buy that amplifier. Here are a few things you need to know for the best and complete approach when combining the elements:


Impedance is a measurement of resistance of an electric circuit, which it provides to a current when it is being applied. The amplifier always has the power and impedance specified on the back side.

Why is impedance important?

This measures the capability of the amplifier to deliver the specified power to the speaker.

For example, if you have a specification of 100 watts and 8 ohms, your amp is adequately equipped to safely deliver 100 watts of power to the speakers with a suitable transformer, power supply, and output. Many of the amps are projected to work with speakers from 4 to 8 ohms.

In case that the lowest impedance is not specified, which can be the case with cheaper devices, it is not safe to use and you should stay away.

RMS (Root Mean Square)

RMS simply is used to explain the power handling capability of speakers or an amplifier. Be sure to buy an amplifier that can provide from 75% to 150% total RMS of the sub system.


Decibel is actually the real measurement of loudness.

It is the logarithmic measurement unit that implies the ratio of two amounts of acoustic or electric signal, that power equals 10 times of the common logarithm ratio.

Deci is 10, bel is the unit of sound, these two equal one tenth of sound. This means that 2 times the power output equals +3 dB(decibel) increase, 10 times the power output equals +10 dB increase, which is twice as loud.

THD (Total Harmonic Distortion)

Total harmonic distortion (THD) is the measurement of deviation from the desired signal that the amplifier produces. This is of great importance for the quality of sound.

Final Words Of Wisdom

Monoblock, or one channel amp, is typically used for powering a subwoofer. With a great monoblock, you can have complete “magic of sound”.

Due to the fact that sometimes an excellent monoblock is all that you will need, don’t rush into buying the best 5-channel amplifier before. Check your well-planned strategy.

The secret to that great bass is in evenly matching the amplifier and subwoofer and making sure they work together properly.

Impedance and power matching are of outmost importance.

Educate yourself about the amplifier installation (and car audio installation in general), proper wiring (circuitry), voltage, car subwoofers and about audio systems in general before you buy your car audio system.

Are you planning on using an iPod, do you need bluetooth for wireless usage or are you happy with just an AUX input?
