Guide to Choosing The Best Amplifier for Your Car! (Types & Brands 2017)

Best Car AmplifiersYears ago, in car audio was a rare and expensive component but today all new cars are equipped with the sound system with cd and/or mp3 player. However, there is an enormous difference between standard audio system and after market one in terms of sound quality and loudness. For all fans of quality in car sound, there are not doubt that aftermarket audio system is the only way to go if you want a perfect sound and very important part of it are the amplifiers. This time, we are going to explain to you what are the amplifiers, main kinds of it and help you buy the best amplifier to suit the needs of your taste in music and your car. So read our guides and product reviews to get the best insight on the amps market.

How Do Car Amplifiers Work

First and foremost we have to explain what the car amplifier really is. The car amplifier is a device which enlarges the audio signal sent from cd/mp3 player to the speakers. In most cases, the car amplifier is necessary since the basic audio signal is too weak and the sound coming from the speakers will not be as good or the speakers will be very quiet. But with the use of the amplifiers, the signal is much stronger and sound coming from the speakers is clearer and more powerful which is something that every audio fan wants.

In its essence, car amplifier is very simple device but the type of amplifiers is determined by the channels it has. The channels are terminals, one positive and one negative, that supply power to a speaker. In general, each channel can power one speaker so the more channels you have the more speakers you can power and the better the amplifier is. In some cases, it is possible to combine two or more channels in one to produce bigger power output if needed. That is called bridging and it is used if you have a very large speaker (like a subwoofer) which needs a lot of power and one amplifier channel simply won’t do the trick.

6 Types Of Car Amplifiers To Consider

There are 6 main types of car amplifiers and four classes (A, B, AB, and D) and the main factor is construction and use. The classes of the amps are an indicator of the circuitry inside an amplifier, basically, the construction and number of transistors used. The best car amplifiers are those with multiple channels and biggest power. Here are the most common types of the car amplifiers:

  • Mono Channel Amplifiers

    The mono channel has only one channel and since it has one it produces more power than multi-channel amplifiers. However, because that mono channels have limited use and they are mostly used for powering subwoofers since those big bass speakers need only one channel. The main advantage of the mono channel amplifiers is their power and very little heat which they produce during transmitting signal to the speaker.

  • 2 Channel Amplifiers

    Two-channel amplifiers have, obviously, two distinct channels and basically, they can produce two speakers or to be bridged to produce more power for a single speaker. There are two main types of two channel amplifiers – class A or class AB circuitry. The class An amplifier uses a single transistor for sending the sound impulse. The advantage of class An amplifier is that the signal is very clear and direct but the disadvantage is that they use a lot of energy and thus create a lot of heat. The class AB is made of two transistors which make it more reliable and energy efficient.

  • 3 Channel Amplifiers

    This type of amplifiers is basically, two amplifiers combined in one. Typically, class AB and class D circuitry are built into a single amplifier and since there are three channels, two are used for speakers and one is used for a subwoofer. It is a good solution for limited space in vehicles with compact interiors but if you want a full amplified sound, you should choose other types of amps.

  • 4 Channel Amplifiers

    A common type of amplifiers with four outputs capable of powering four speakers or two speakers and one powerful subwoofer with bridging of two channels. The four amplifiers are used in most cars and they power two front and two back speakers giving a nice audio effect in the car’s interior.

  • 5 Channel Amplifiers

    Like the three channel set-up, the five channel amp is basically two amplifiers combined in one. In this case, there is one four channel unit combined with one single channel amp for powering four regular speakers and one subwoofer. The single channel (subwoofer) is more powerful than the rest since it requires more power. This layout is common and very usable since it fulfills the most tasks and gives enough channels to power four speakers and subwoofer which is enough for great in-car sound.

  • 6 Channel Amplifiers

    This is a less common type but usable for a specific purpose, mostly in large cars with much interior room like SUV. It can power 6 individual speakers of four speakers and one big subwoofer due to the bridging of two channels. If you are planning on building a hi-spec audio system for your car, the 6 channel amp is recommended since it will answer all of your needs for power and number of outputs.

How To Choose The Best Car Amplifiers For Your Car

Since there are many choices and quite a few manufacturers of car amplifiers and audio components, you should read this buying guide in order to find the best car amplifier for you. There are a lot of things to take into consideration, not just the amount of money you are willing to spend but the size of your car and your personal music preferences, because, the jazz music needs a different set of audio components than drum ’n’ bass. So, here we go:

  1. What Is The Size Of Your Vehicle?

    The dimensions of the car play an important part in choosing the right car amplifier since you can not put a big one with subwoofer in a tiny car or sports roadster. Or put small amplifier with just two speakers in big SUV with lots of space. That is why you should first research the dimensions of the interior and the trunk of the car (for subwoofers) in order to narrow down the choice.

  2. What Kind Of Music Do You Listen?

    Very important question is about your music taste. The type of music will influence your choice of amplifiers and other audio components because not every in-car sound system is for every music type. If you like music with a lot of strong bass sounds you will look for amplifiers which could power bass speakers or subwoofer. If you looking for more delicate sound, you will look for amplifiers which can power four or six inside speakers for perfect clarity and detail.

  3. Know The Basic Tech Behind The Amplifiers

    We have explained to you few basic of what the amplifiers are and how they work but we suggest to you to learn more in order to know the difference in materials and construction. Knowing the type of cables, transistors, terminals, connectors are used in making of the amplifier really can tell you whether it is a quality product that will suit your needs or not.

  4. Set A Budget Limit

    Since there is a whole industry of car audio systems and car amps it is easy to spend much money. But, set the budget limit and stick to it in order to get the best deals and most for your cash. Some things you need could be second hand and not new since their quality is not affected by previous use so search forums, second hand adds to find the best deals.

  5. Buy Additional Components

    If you want really good and versatile sound system you should invest in some additional components which can make your life much easier and safer. For example, buy remote amplifier controls by which you can switch subwoofer on and off or change the power of the audio impulses which are delivered to speakers. This way, you can change settings of the amplifier to suit different music styles. On the other hand, important gauges are car voltage monitor which shows you the amount of power is used and needed for proper function of the amplifier and heat monitor. When the amplifiers work with multiple speakers on the peak of its power, amplifier gets hot. And sometimes so hot that it can cause a fire or burn down of its components and transistors. So if your system is very powerful and the amplifier is under a lot of stress it is advised to monitor its temperature just to be safe.
