5 Best Car Amplifiers 2019 – Stereo Amp Buyer Guide (Updated)

Have you ever had the experience of listening to a song at home and loving it, then getting in your car, playing the same song and wondering why it sounds so much worse? If you’re like a lot of us, you blame it on your lousy speakers. But they may not be responsible; it may be the car amplifiers.

An amplifier is a device that takes a weak signal and makes it stronger. Cars are manufactured with amplifiers, but they are not powerful enough to handle the distortion that comes with varying signal strength.

If you’re irritated with the quality of the sound coming out of your car speakers, it’s probably time to think about car amplifiers. But how do you know what to look for when you go shopping?

If a car has already a built-in amplifier, so why use an external amplifier? The reason is simple, a best car stereo amplifier cannot handle the power of subwoofer except in the rare case, especially happens quickly in the increase of high volume.

What is the best car audio amplifier?

 

What is an amp?  the amplifier gives power source to the sound system, as some speakers especially subwoofers need the power to express themselves. Technically, the amplifier modulates power generated from the car battery, which is DC volts, the most preferable for the sound system you might observe that the CAR music is always better than home theater which CAR DC source is the one of reason.

“So if you want your car music to be loud the amplifire sould be powerful”

How to choose amplifier for car speakers and subwoofers?

There are technical dimensions and user requirements to consider when you’re ready to buy your amplifiers. Some of these may be more important to you than others, but they still need to be considered.

Power Output – The measure of how loud the sound ca Rockville dB45 3200w Peak / 800w RMS @ 4 Ohm CEA Compliant Mono Car Amplifier, Loud!! n be amplified.

Total Harmonic Distortion + Noise – The measure of distortion the amplifier will correct (lower number = less correction).

Signal to Noise Ratio – The measure of how much background noise the amplifier will create (higher number = less noise).

Crosstalk – The measure of how much the left signal is mixed with the right signal (low number = greater separation). Greater separation = less distortion.

Intended Purpose – Whether the car amplifiers are intended to be used to improve sound quality in the car’s original speakers, for use with new speakers, or to power a subwoofer for very low frequencies.

Space Constraints – The amplifiers can be put under a car seat, in the trunk or against the fire wall across from the driver. The space available will impact the type of car amplifier.

Number of Channels – The general rule is that you’ll need one channel for each speaker.

Power for the Speakers – It is better to exceed the required power to the speakers to avoid destroying the speakers at maximum volume.

How to select Best Car Stereo Amplifier?

Car Amp Classes

An amplifier is essential in a quality installation. There are different types of amplifiers for different uses. Their efficiency is much different here we only discuss which are top related to audio systems.

  • class A amplifier
  • class AB amplifier
  • class C amplifier

What is class A amplifier?

Class A and its very low efficiency are reserved for domestic use,

class AB amplifier (best car audio amplifiers)

Class AB is used in the majority of the best car audio amplifiers. It is an excellent compromise between softness, sound quality, and efficiency. This type of amplifier is generally used for the front speakers and rear.

class D amplifier?

The class D shines by its high efficiency: it provides more sound and consumes less power. His warm-up is also much lower. Less qualitative, but more quantitative, this class of amplification is very often used for the reproduction of low frequency (Subwoofer).

Amplifier channels

There are two essential categories classified from A to D. These categories of the amplifier can be classified into two major classes,

Mono amplifiers 

Mono amplifiers or monaural or monophonic amplifiers generally reserved for the bass channel. they are an excellent choice for powering subwoofers.

Multi-channel amplifiers:

2-channel

that amplifies two speakers (left and right) or 1 subwoofer

4-channel:

which offers the possibility to power 4 speakers to choose from, namely 2 front speakers and two rear speakers or 2 speakers and 1 subwoofer.

“Rather than to mount multiple amplifiers like one for the front channels and one for channels rear, I will recommend you to move towards an amp 4 channel”

The 5-channel:

it powers at the same time 4 loudspeakers (2 front speakers and 2 rear speakers) and 1 subwoofer

Power of amplifiers

The first thing is to check the power. You must make sure that the RMS power based on the impedance that can sustain your speakers or your subwoofer is equal to that provided by your amplifier. But the best for a good operation of your audio equipment is to acquire speakers or a shallow mount subwoofer that can support double the power of the amplifier. a HP must have the same RMS power that the amp (50W rms-> 50W RMS amp Hp

Signal to noise ratio

It is the measure of the level of background noise added to the original signal by the amplifier. The value, the more the amp is well built (-85dB is better than – 75dB).

THD + Noise (distortion by harmonic rate)

This is the measure of the difference between the original signal and the amplified signal. This rate is low (THD = 0.01%), more the amp is faithful and powerful.

Amplifiers Wiring

Two other types of wiring are required also to the amplifier. Not only must it be connected with the source that is the car stereo, but it must also be connected with the speakers. The use of suitable cables is also recommended. You also have the option to use a capacitor to get an even more powerful car amplifier.

Take into account the power supply

The amplifier consumes a lot of power and so needs a direct electric line from the battery. Should it be equipped with a cable of the adequate section and independent protection through a fuse
