For all the audiophiles out there, having an amplifier installed in your car stereo system is a blessing. 

Because it improves the sound’s tone, linearity, clarity, bass, and loudness. However, Some people may find it difficult to pick the right amplifier for their car.

Since I’ve been doing it for a very long time for my cars, I consider myself a pro at car amplifiers.

This article explains how to choose an amplifier for car speakers?. To get everything in a good way, make sure you stay around till the end.

An Amplifier/ A Quick Overview!

How to choose an amplifier for car speakers?/ All The Factors That You Need To Consider!

Hearing aids use tiny parts called amplifiers to increase the volume of voices. Large black boxes can also be used to raise the roof and audio equipment to drive your loudspeakers. 

An amplifier can improve the sound quality of the car stereo system. But, now you’ll ask” How do I choose an amp for my speakers?”

Car Speaker Amplifier Selection

In order to choose an amplifier for your car speakers, you need to take into account a few factors.

There isn’t so much difference between a car amplifier and a regular amplifier. But the car stereo music system is quite different from the normal music system in your home. So, make sure you keep the below-mentioned things in mind while choosing the amp for your cars.

Power Output:

Amplifiers can produce a maximum volume at this level. Depending on the speakers that will be used with the amplifier, the desired power output will differ. 

(SNR) Signal-to-Noise Ratio 

Electronic currents generate background noise in amplifiers. This noise’s SNR indicates how noticeable it would be. The SNR value of an amplifier determines how much noise is heard.

What’s your purpose?

Your purpose matters a lot when you’re choosing an amplifier for your car. Because the type of amplifier will be different according to your purpose. 

Let’s say you want to improve the quality of the sound by making it louder, clearer, and deeper. The best choice for you would be a compact four-channel amplifier.

The amplifier should, however, be capable of delivering at least the maximum RMS wattage of the speakers in the system if it is designed to optimise the performance of aftermarket speakers.

It is necessary to add a single-channel amplifier to any other amplifier in the system if you just want to power a subwoofer.

Crosstalk:

Left and right signals are produced by stereo amplifiers. The amount of crosstalk between two signals is measured by crosstalk measurements.

The lower the decibel value, the greater the stereo separation between the left and right signals.

Room for a subwoofer:

The gadgets may be worth the investment if you’re an audiophile. The amplifier is a must-have if you have a subwoofer in your car or plan to install one soon.

Subwoofers should not be connected to stereos without amplifiers since it distorts the sound more and destroys what little music remains.

Number of Amplifier Channels

Depending on the number of speakers in a vehicle, an amplifier requires a certain number of channels. Each speaker in the car’s sound system, including the subwoofer, requires one channel.

Speakers can be powered by amplifiers with even numbers of channels, even if the number of speakers exceeds the number of channels.

Go For 75 to 150 Power!

The more powerful your amplifier is, the better and more speakers it’ll be able to power. A lot of the time, people end up buying less powerful amplifiers that fail to power multiple speakers in their cars. 

This is a mistake you should avoid, mate. Speakers in a system should receive 75 to 150 percent of their RMS value from an amplifier. 

There is an old saying that it is better to have more power than you need for a speaker than to have too little since too little can fry or blow up the speakers in a car’s stereo.

Make Sure The Amp Is Compatible With Your Head Unit!

In most cases, factory head units do not have preamp outputs, so the amplifier would need to have speaker-level inputs.

As opposed to preamp outputs, line-level inputs are required for head units with preamp outputs (which, by the way, results in the clearest sound quality). 

Ensure that the car’s head unit has preamp outputs first before purchasing an amplifier that is incompatible.

Make sure the warranty is valid

There is no guarantee for amplifiers bought from unauthorised brands. In no time, it may stop working, and you will have to replace it. It won’t be possible to return or replace it if there is no guarantee.

You should therefore purchase an amplifier from a reputable and well-known brand. More information can be found on the official website of the brand.

Budget

The most important thing is to consider your budget. Depending on the brand and amp specifications, prices vary.

It is important to purchase an amplifier that fits both your budget and the requirements of your system. There are times when used items can be found at a great price.

FAQ

1. How many channel amps do I need for 4 speakers and 1 sub?

In order to power both the speakers and the subwoofer, you will need a two-channel amplifier. For four tri-amplified speakers and a dedicated subwoofer, a 4-channel amplifier is needed.

2. What is 0dB on the amp?

When it comes to amplifiers, 0dB indicates their maximum output power. For example, the Yamaha MusicCast R-N803D can deliver 2 x 100 watts into 8 ohms at 0dB.
