How To Choose Best Car Audio Amplifiers – Do’s and DON’T

Last Updated on 2 years by On Trends Gear

You’ve decided to upgrade your car’s sound system and are looking for the best car audio amplifiers to do the job.

 You’ve undoubtedly decided it’s time to improve your car’s stereo’s sound quality. A robust amplifier is a necessary tool in this regard. 

If you want your car audio to sound its best, invest in a robust amplifier that is compatible with the rest of your equipment.

Your speakers, subwoofer, and intended installation location all play a role in determining the sort of amplifier you’ll need for your automobile. 

Learn what factors to think about while shopping for an amplifier to run your speakers and subwoofers in this post.

What is an Amplifier?

An amplifier is a piece of electrical equipment that can boost the signal’s strength, voltage, or current in some way. 

 Car audio amplifiers are a common component in audio equipment of all sorts, as well as in wireless communications and broadcasting. 

One of two types of amplifiers—power amplifiers or amplifiers for weak signals—can be assigned to them.

Why Use the Best Car Audio Amplifiers?

Amplifiers are an essential component if you demand a deafening volume from your tunes. 

However, a power amplifier will bring your music to life, bringing out all of its excitement and detail whether you play it loud or soft enough for conversation. 

Some of the most notable gains from installing Best car audio amplifiers include:

#1. Better Sound Quality

A clean power source that is easily capable of driving your speakers is what you get from an amplifier. 

When compared to an amplifier that is built into a dash-mounted stereo, the design of an external power amp provides designers with a greater degree of creative leeway. 

Your music will be heard with increased clarity and a higher level of detail at any volume.

#2. Power for Speakers With Better Sound

In certain vehicles, the factory radio or in-dash receiver simply is not capable of providing adequate amplification for aftermarket speakers.

 If you upgrade your car’s sound system with high-end aftermarket speakers or a separate component system, your vehicle’s factory head unit might not be able to keep up with the power requirements.

#3. Powering a Subwoofer

Subwoofers have power needs that are typically not met by a generic or stock in-dash receiver. Having a separate amplifier is essential.

What to Consider When Choosing a Best Car Audio Amplifiers

#1. Power Output

Do you have an idea of the maximum volume level that your speakers are capable of producing?

 Because the speakers on your system generally have insufficient power, the sound that they produce is extremely lifeless and uninteresting. 

When putting together an in-car entertainment system, the first step is to choose the speakers. 

After that, all that is left to do is choose the most suitable amplifier to power them. Do not take any shortcuts; instead, emphasize having stable power.

 It is important to ensure that the output power of your amplifier is at least comparable to, if not superior to, that of the speakers to which it is connected.

 Confirm that the speakers you wish to use have an adequate RMS power rating. After that, you need to look for an amplifier that has the capability of delivering at least 75% to 150% of the output power that it advertises.

#2. The Power of Your Speaker

In its most basic form, a subwoofer is just a huge speaker that has been optimized to generate low frequencies. 

When thinking about RMS wattage, the same guidelines should be followed as before. 

It is recommended that the maximum RMS power output of the amplifier be about equivalent to, or slightly lower than, that of the subwoofer. 

You must examine the impedance ratings of any sub amp that you are considering purchasing. 

This is because the electrical charge resistance of an amp alters when it is linked to several subs.

#3. Ability to Work With Your Car Stereo

In most cases, aftermarket amplifiers can be installed with the factory stereo, however, the OEM radio will not have preamp outputs. 

Speaker-level inputs are available on many amplifiers, allowing you to tap into your car’s pre-existing speaker wiring. 

Many amplifiers have a digital signal processor (DSP) that improves upon the original sound quality.

#4. The Ratio of Speakers to Channels

Amplification with multiple channels is required if you want to power a large number of speakers, although amplifiers may be set up in a variety of ways to fit the requirements of different situations. 

By connecting two channels to produce a single channel with increased output power, it is feasible to utilize a four-channel amplifier to drive two speakers in addition to a subwoofer. 

A 5-channel amplifier is what you want if you want to make use of four speakers in addition to either one or two subwoofers.

#5. Amount of Channels

How do you know how many channels your system should have?  Well, That is contingent upon the number of available speakers. 

Having extra speakers means you’ll need more channels. Usually, you’ll need a separate channel for each speaker.

 If you’re looking to add a subwoofer, a mono-block or single-channel amplifier is what you need.

But the adaptability of multichannel amplifiers is much higher.  To illustrate, a two-channel amplifier can power two sets of speakers and two subwoofers. By bridging the amplifier, only one subwoofer may be powered.

As we’ve established, a car’s audio system can include several speakers powered by a single multi-channel amplifier. 

For instance, you may use a new mono-block amplifier for your subwoofer while still employing your existing four-channel amplifier for your other speakers.

Conclusion

Installing and wiring a Best car audio amplifiers does not need a high level of technical expertise; nonetheless, you should give some thought to the position of the amplifier as well as how the wires will be routed before you go shopping for a unit.

 Because the majority of automobiles do not arrive from the factory equipped with amplifiers, you will need to locate a technician to have the necessary hardware installed. 

Keeping this in mind, taking a few measurements before purchasing an amplifier can help to streamline the process.
