Best Car Amplifiers Buying Guide

After you have reviewed all the amazing products mentioned above, it is now time to see why those features are important to consider. In this buying guide, we will be answering some important questions. We will also be discussing the four main specifications of an amplifier that you need to look out for.

Purpose of an Amplifier

You will hear many people talk about amplifiers and how great they are. These are, in technical terms, described as pieces of wire that provide a gain. However, in simpler terms, an amplifier is a device used to increase or boost the volume of a speaker.

best car amplifiers

Working of an Amplifier

A device cannot simply increase the volume; you will also need some additional components to make the unit working. An installer will first connect the amplifier to the radio, and then he will connect the amp to the speakers. It is important to ensure that the current needed by the amplifier is provided by your car.

Need For The Amplifier

People love to enjoy loud sounds in their cars, and normal speakers don’t always provide that. And even when they do, they normally distort the sound and make it appear unappealing.

An amplifier, on the other hand, offers a good signal to noise ratio. This will limit the distortions to a large degree.

Factors To Look Out For

There are many features that you will have to look out for. However, in this section, we are discussing only four features that you need to prioritize. This will make or break your model.

Number of Channels

The number of channels on your amplifier will greatly influence the intensity of the sound and the diversity that you achieve. In the recent decade, multichannel amplifiers have gained popularity for their unmatched performance.

These usually come with a five-channel design and allow a boosted sound for both front and rear speakers. However, contrary to what people believe, these amplifiers only require one set of connections, and there is a simple remote that is used to adjust settings.

Moreover, these are relatively expensive, so if your needs aren’t too intense, you can also invest in a single or dual-channel unit.

Power Settings

This also needs to be considered while looking for an appropriate model for your car. The power specifications are rated in Watts and determine how much energy the amplifier can provide to your speaker.

best car amplifier

Car units are designed to increase the voltage. While shopping, you need to keep in mind that any unit with too much power rating will also draw a lot of current from your car and may result in higher running costs.

So, for instance, a 2000 watt amplifier will have to draw a massive current of 200 amps from the electrical system of your car. This is why it’s recommended that you buy an amplifier, keeping in mind the type of car and your budget.

Noise Production

This is probably the thing that bothers most amplifier owners. Many bad-quality units produce a lot of distortions at higher frequencies. As soon as the volume goes up, the noise distortions also go up.

It is difficult to assess the quality of your unit based on how well it works in other cars. However, a quick way to estimate whether your unit will produce too much noise or not is to check the signal-to-noise ratio. This number is expressed in decibels.

So while buying the unit, make sure that this number is large. This is to ensure that the amplifier doesn’t produce too much noise while producing intense sound.

Signal Processing

You can have the best of all the features, but without fast processing technology, there is really no point in investing in such a model. The gain control of a unit will allow the installer to calibrate the amplifier so it can easily be used with different source units.

You obviously want your unit to be able to work well with a radio that produces a voltage of 2 Volts and a radio that produces a voltage of 5 Volt. This not only provides greater diversity but also ensures you don’t have to take your unit for many adjustments.

The upper-frequency limit of the unit is 250 to 500 Hz, whereas the lower frequency limit is 40 to 50 Hz.


A good amplifier will ideally draw a large current from your electrical system. However, you will have to find a balance between the voltage it draws and the expenses you can bear. The best model that lets you do this is Kicker 46CXA8001.

It comes with a medium form factor and is able to generate a large power without consuming too much current. It is also very durable and offers good compatibility.

You can also look at other models that fit your criteria, but no matter what you do, never go on a long trip without an amplifier; there is really no point in it.
