Welcome to the BestCarAudio. You will often hear the perfect amplifier described as a piece of wire with gain. Gain implies that the amplitude of the signal put into one end of that wire is increased as it exits the other end. The number of components and their configuration depends on how much power you need, how much voltage you have available to power the amplifier itself and the features included in the amp.

To keep it simple, an amplifier takes a weak signal and makes it more powerful. Think of the amplifier as the heart of the system, it is the device that provides the power to move the speakers.

If your speakers are underpowered they are not working to their maximum potential, which leads to poor sound quality and may even harm your speakers. For the most part factory installed stereos provide very little power output to drive your speakers. If you are thinking about adding an amplifier to your car stereo because your system has lost its luster, but are still using your factory installed speakers, you may want to start by replacing your factory speakers. Typically factory speakers are not of the highest quality and tend to wear out over time.

Power Rating: Amplifier power ratings are categorized in two measurements. When looking for an amplifier, be sure that you are taking note of the RMS power rating and not the Peak power rating. There are numerous amplifiers on the market that claim that they will produce thousands of watts of power for very little money. These types of amplifiers are built with inferior electronic components. Sure they will amplify your signal, but not to the numbers that they claim.

Inexpensive amplifiers tend to produce a lot of signal noise and typically have a very short life span. If you are looking at an amplifier that is rated at watts peak power and watts RMS power then it is really an watt amplifier. It is good practice to look for amplifiers that are CEA compliant. There was a time when car audio amplifier manufacturers could rate their amplifiers any way that they saw fit.

This led to unsubstantiated claims of tons of power in a small package for very little money. When you compare an amplifier that is stamped with the CEA logo to another CEA amp, you know that these 2 amplifiers were tested the same way, and that you are comparing apples to apples.

Amplifier Configurations: Amplifiers come in a number of different configurations, which one is the best for your application depends on the amount of channels that you require.

A channel is the powered signal that an amplifier sends to a speaker. Typically the amp is configured to one channel per speaker but there are exceptions. This is the measurement of resistance that the speaker adds to the circuit. It is very important to match your amplifiers impedance to your speakers impedance. When and amplifier meets very little resistance it then begins to produce more output power than it was designed for and will cause damage or failure to the unit.

So it is important to make sure that your amplifier impedance matches the impedance of your speaker configuration. When a speaker is underpowered there is the potential of overdriving the amp. This happens when the volume is turned up so loud that the amplifier can no longer produce a constant signal, resulting in audio breakup or distortion known as clipping.

When this happens the amplifier sends harmful signals square waves to the speakers, and these signals can not be reproduced by the speaker resulting in damage to the speakers themselves causing loss of output or even failure.

This is especially harmful on smaller, more delicate speakers such as tweeters. When the amplifier is driven to the point of distortion peaking or clipping , not only is it harmful to the speakers it also causes damage to the amplifier as well.

When an amplifier reaches the point of clipping it can result in permanent damage or failure. Matching the exact RMS Power of your speakers to the RMS Power of your amplifier seems like the logical thing to do, and yes it allows for great sound. The additional headroom will enable your amplifier to contend with any sudden spikes in the audio signal. When an under powered amplifier receives an audio spike, it will not have enough power to reproduce the signal, instead it will produce a distorted signal.

If you have an amplifier that is rated at 50 Watts RMS the Red horizontal line , you will notice that there are plenty of spikes in the audio that surpass the 50 watt range of your amp.

These spikes will still be audible, but they will most likely be distorted and will cause your amplifier to produce excessive heat when they are reproduced. If you had an amp that was rated at 75 Watts RMS the Green horizontal line , you will notice that none of the audio spikes reach the 75 watt range, and the amplifier has plenty of power to reproduce the audio signal clearly without distortion.

You will have the same volume without the distortion. The space between the Red and Green lines is what is referred to as Headroom. Headroom is basically how hard you can push your amplifier before it will distort. It is always a good idea to have plenty of Headroom within your system for this exact reason.

A more powerful amp will give your audio system more headroom, and improve the sound quality of the audio. The more power will let you turn up the music before the amplifier distorts. However if the speakers can not handle the additional power they will distort. Wiring: Manufactures recommend wiring specifications in terms of gauge thickness and material of wire for their products.

Bridging: When 2 channels are combined to create one channel. This process cuts the ohm load in half therefore providing more power to the speaker that the amplifier is powering.

This practice is commonly used to power subwoofers on a multi channel amp. For example if you have a 4 channel amp, channels 1 and 2 are used to power your left and right speakers, channels 3 and 4 are bridged to power a subwoofer.

Note: Not all amplifiers are capable of bridging. Audio Filters: Filters are an electronic device that can be found within amplifiers that control what frequencies are sent to your speakers.

This is extremely helpful because they allow you to fine tune your amplifier to your speaker selection and your vehicle. Filters are available in both Fixed and Variable. A Fixed Filter is a filter that has only has one setting that is predetermined by the manufacturer.

A Variable Filter allows you to adjust the setting of which frequencies are affected by the filter. Adjustable Input Level: This function allows you to boost or cut the signal that is sent to your amplifier from your car stereo.

This helps you dial-in the input signal strength to your amp to help minimize distortion within your unit. Adjustable Output Level: This provides control over the signal strength that the amplifier sends to the speakers, to ensure that your speakers are not inadvertently overdriven and protects the amplifier from distorting or overheating.

Some of these tones may never be heard individually but when they are combined with the original audio of a recording, it breathes new life into the recording, offering more depth and ambiance. Speaker Level Inputs: Enable you to use the speaker outputs from your car stereo to send signals to the amplifier.

This is especially helpful when you do not have line level outputs RCA on your car receiver. Although there are many different classes of audio amplifiers, only a handful of amp classes are commonly used in the world of car audio. Without going into a lengthy explanation on the physics of how each amp class works, it is much easier to understand the pros and cons of each amp class.

Listed below are the most prevalent amplifier classes used within the industry. Class A: An analog amplifier.

Mainly used in higher end car audio installs. Not commonly found in car audio. Class D: Digital amplifier. The most common amplification found in car audio. This type of amplifier generates a fair amount of crossover distortion.

In order to minimize the effect of the distortion, the audio quality may suffer, depending on the make and model of the amplifier. Amplifiers come in many configurations.

Amplifier Buying Guide What does an amplifier do for your stereo? This is the rating that industry professionals are most concerned with, and it is a more concise reflection of the amount of power the amplifier is capable of producing.

Once the amplifier has surpassed its RMS Power rating it will begin to generate heat, distort, and may cause damage to the unit itself. Peak Power: How much power the amplifier can produce for a very, very short period of time before damage or failure occurs. Sure the amplifier may be capable of producing the claimed amount of power, but it will not sound pleasant and it will not be long before the amp shuts off or blows.

Therefore it is deemed as a useless measurement of power output and is not considered a worthy rating. Under Powering Your Speakers When a speaker is underpowered there is the potential of overdriving the amp. How much power do you need? Features Audio Filters: Filters are an electronic device that can be found within amplifiers that control what frequencies are sent to your speakers.

Filter Types: High Pass Filter: An electronic filter that allows signals higher than a specified frequency to pass through its circuit, frequencies below the specified frequency are muted. Low Pass Filter: Exactly opposite of the High Pass Filter, this filter allows all frequencies below a specified frequency and all frequencies above the specified frequency are muted.

Subsonic Filter: Mutes the ultra low frequencies that are not in audible range, this reduces the workload of both the amplifier and the speakers. Why have your audio components reproduce audio that you cannot hear? Amplifier Classes Although there are many different classes of audio amplifiers, only a handful of amp classes are commonly used in the world of car audio.

Pros: Extremely accurate output No crossover distortion Very good high-frequency response. Pros: Decent quality audio output More efficient than Class A amps. Cons: Crossover distortion Generates heat Very inefficient Expensive. Pros: Acceptable crossover distortion levels More efficient than Class A amps. Cons: Generates less heat than Class A amplifiers Expensive. Cons: Crossover distortion Sound quality.

Top 11 Best Car Audio Amplifier Brands In The World 2021


A car amplifier is the heart of your car's stereo and whether you are looking to power a set of 6. Most people believe that their car's OEM stereo has enough power for their speakers, or that their new aftermarket stereo putting out 50 watts per channel peak is enough for a great sounding system. For example, a 50 watt Peak per channel aftermarket stereo might actually only be pumping around 15 watts RMS to each of your speakers. And an amplifier that is rated for watts might only put out half of that continuously RMS. Powering your speakers aftermarket or not with the correct amount of power can mean a WORLD of difference in the performance of both subwoofers and speakers alike. You may have the highest performing speaker or subwoofer but without the power, it means nothing.
