How to choose the best amplifier for your car | Buyer Guide

If you want to improve the sound quality and bass of your speakers, you need a car amplifier. They allow you to control and amplify electrical audio signals at high voltages, after which the speaker is used to drive the car from the inside. They are categorized into classes and feature multiple channels to power the extra speaker.

You can have a good car that takes you from one place to another. But is your car really complete without a good sound system?

To make a great sound in your car, you need two things: a good parasite and a good speaker. For the sake of this article, we will only talk about amplifiers and how they are essential in producing the sound you amplifier for your car

Since we’ve worked with you to review all the different types of car amplifiers from the monsters of the best 5 channel car amp to the monoblock AMP, we thought we’d come up with a guide to avoiding the best cars.

Why do you need best amplifier for your car?

The main reason for the car amplifier is to amplify the low-level audio signal generated by your head unit. It gives your subwoofer cone the power to transmit this hard-hitting deep bass and other car audio speakers.

When active subwoofers are running, you will need a powerful car AMP to move the cone. On top of that, you should also invest in a more rated and powerful dual-dan stereo or single-dan stereo with more results.

Here are 3 reasons you need an amplifier for your car.

Sound Quality – When you talk to a great AMP about clarity, responsiveness and sensitivity, you’ll notice significant improvements.
Powering your subwoofer – Generally, factory issue AMPs don’t cut it if you need to run heavy-duty sub. Investing in AMP will not increase your woofer capacity.
Powerful Speaker – When you decide to upgrade your speaker, don’t underestimate the importance of upgrading to AMP to maintain speed.
What to think about when choosing


What to think about when choosing the best amplifier for your car?


First, consider the budget. You cannot make a final decision before you are sure about your budget. Car amplifiers come in different price ranges. In general, the more expensive the AMP, the better the features. However, sometimes this is not true. In any case, you have to keep a certain amount like 100 or more. One hundred dollars covers a large number of amps so you can make easy decisions.

The number of channels?

First of all, you need to consider the number of channels. An important aspect to consider when looking at a car amplifier is deciding how many channels are needed. The power of an amplifier is distributed between channels. For example, if there is 300 watts of power between 3 channels, each will have 100 watts.

Speakers that run on cheap amplifiers can be distorted. You better buy a more powerful car AMP that runs without pressure for better quality.

For convenience, we’ll stick to the 4 categories we’ve reviewed here on the site.

Monoblock Amp – Designed primarily to power subwoofers, they provide ample firepower without the need for such a clear signal. Since all rarely run high frequencies, most monoblock AMPs are not full range. Monoblocks are designed with strength and power in mind.

2-Channel Amps – A very popular choice, 2-channel amps are versatile units. Electricity is supplied to a couple of channels. You can either power a pair of speakers or build a bridge over it so that there is more output in one channel which makes a perfect fit for 2 channels if there is something in your trunk.
4-Channel Amp – If you’ve got a full range of door speakers, consider splitting up on 4-Channel AMP. Although they are also capable of AMP bridges, most of them are used for a set of speakers.
5 Channel Amp – Combining a monoblock and 4 channel amp, the 5 channel unit puts the need for more than one AMP behind more sophisticated sound systems. They do not work for power hungry applications.


The data that counts is the RMS power. Unless you fully understand, focusing entirely on the power of the peak can be misleading at best. Impedance is measured in moments. The lower the amplitude rating, the higher the wattage than the AMP. Buying the best amp for your car that is too weak for your speakers is a recipe for disaster that will lead to distortion and frustration.


In scientific terms, impedance is the effective resistance by rotating the electrical circuit. You do not want to be frustrated if you cannot get the right pitch so invest in a good capo. All you need to know is that the impedance rating should be the same for both your AMP and your speakers/ subwoofer output


The perfect match will result in the best output of your sound system. If you are still interested in learning about the barrier, you can take a look at this informative video that explains the concept of the barrier in detail.


Most factory head units do not already have amplifier stores, make sure your AMP has speaker level input or consider upgrading the head unit instead.

If you are choosing to configure a complete system from scratch, look for head units with pre-amplified outlets in which you must select an in-depth with line-level input. Spending time at this stage can save you time and money.

Amp size

Don’t overlook the physical size of the units you are considering. If you do not have real estate to keep you comfortable, it is useless to put your money into a real animal.

You can get a lot of powerhouse MPs in compact bodies so don’t be fooled into thinking that you need to take the hulking giant.

Technical specs

We try to avoid bombarding you with technical specifications in our summary reviews but, once you submit a shortlist of your best car amplifiers, it is up to you to double the specs. Is beneficial

It pays to develop at least one basic foundation in the following areas:

Sensitivity – Measures the performance of this AMP. The higher the sensitivity, the louder it will sound. Optimized sensitivity also leads to lower heat generation
Frequency Response – This is related to the tone or pitch of the sound. Frequency rating indicates how well your AMP will be able to handle sound
Decibel Rating – To put it bluntly, this shows you how high the AMP will be.


When everything is done and it gets dirty, all you have to do is install the car equipment in your car. You need to decide whether to do it yourself or find an experienced electrician to do it for you. Car AMP is not easy to install. There is a lot of science going on that can be annoying for the average person who has no relevant experience. A professional will charge you some money but will definitely get the job done.

If you install the car incorrectly, you run the risk of blowing up your speaker or subwoofer. Therefore, it is best to protect yourself from the technical limitations and hand over the lap to a professional tenant. You will save time and learn some valuable things about AMP.

Car Amps For Bass

For those who enjoy hard-hitting bass, you need a low pass filter amplifier. The purpose of this filter is to deliver low-frequency audio to the subwoofer.

It is important to note that if you have set your receiver for low pass filters, boss boosts or crossovers, do not do so with an amplifier. This will increase the distortion and may reduce the overall sound quality.

Enhancing the bass with an improved amplifier that matches your speaker wattage is a great way to enhance performance and bass for your car audio setup.


Frequently Asked Questions ( FRQs)

What are the different types of amplifier Classes?

An amplifier class amplifier is a type of electronic circuit and feature structure. Different classes often have different performance, efficiency, and power resources.

There are five main types of amplifier classes used in different amplifiers. They are A, B, A / B, G&H and D, who all have pros and cons.

To get started, Class A is the simplest and uses the same transistor in linear format. Class B uses a pair of transistors in a push-pull application, which is more efficient than class A but can be crossover distorted.

Class A / B is used for the lowest cost designs and is a mixture of A and B, a small constant current when no input is present. When the input signal is at a very high voltage, only one transistor will run, but when the input signal is zero voltage, both transistors will run.

Class G / H is a better class A / B where both work on the power supply section. If the output power is high, then a high voltage power supply is required. Class D is mostly used for low-cost solutions where devices act as electronic switches as opposed to linear advantage.

What does it mean to bridge an amplifier?

For audio installers who want to use a wafer without using a monoblock, bridge feeding is a way to increase the power of an amplifier channel.

For example, 2 x 100 watts can create 1 x 200-watt channels. The majority of 2 and 4 channel amplifiers can power a subwoofer.

Amplifiers with 3 or 5 channels such as JL audio amplifiers are sometimes dedicated to subwoofer channels that reduce the need for a bridge between channels.

For those who are new to car amplifier bridges, we strongly recommend that you check out this guide How to bridge 4 channel amp? before attempting to do it yourself.

What is a car stereo amplifier?

A device installed in a car that receives low input audio signals and amplifies its amplitude is called a car stereo amplifier, This amplifier usually gets its power from the car’s deck or head unit and gives it more power before sending a signal to the car’s speakers.

Can you use a bass amp as a subwoofer?

Yes, you can use Boss AMP as AMP. Just enter what is necessary in PA (such as vocals, keys, etc.), and use the volume of your stage to balance the group. It would be much more effective (and make you a better musician) than to hack a bass amp / all together and hope for the best.
