Why You Need To Add An Amplifier To Your Car (And How To Choose The Best One)

Anyone who has experienced getting stuck in traffic knows just how much of a saving grace a good car sound system can be. You don’t exactly need to be a music connoisseur to crave for some quality tunes when you’re on the road, especially if you’re someone who prefers a little bit of background distraction during such a mundane activity.

This is just one of the many reasons as to why so many car owners choose to upgrade their sound system by installing amplifiers. Amplifiers, for those who are not familiar with them, transform low level output into a higher one so they can be picked up by speakers. 

Now, most car systems come with basic factory sound systems with built-in amplifiers, but these are not usually powerful enough to provide clear and solid sounds. This, among other reasons, is why this upgrade has become a favorite modification among car owners. In fact, many motorists even have amp upgrades as the first thing they do to their vehicles.

Of course, there are other ways amplifiers can contribute to a car’s sound system other than just increasing the volume output. If you think that any of the benefits below is something you’d love to have in your car, then it’s about time you start looking for the best amplifier for your needs.


So, why get an amplifier? 

Amplifier To Your Car

They upgrade sound quality

Few built-in car sound systems are loud enough to provide good volume AND good sound quality at the same time. Another perk of having car amplifiers is that they remove the possibility of sound distortion, something that factory speakers tend to create once you crank them up to their maximum volume capacity. Amplifiers also improve the bass and create cleaner sound feedback.

They let you customize

If you’re someone who is serious about music, then adding an amplifier that can let you access customization features (e.g. equalizing) should be a top priority. This is especially true if you have an older version of a car stereo system that doesn’t really offer these perks. Adding an amplifier to your vehicle will let you have more control over the sound without you needing to install a whole new stereo player.

They give better sound focus

You’ve probably already noticed this, but there are so many sounds—engine or traffic noise for example—that can usually seep inside your car. Adding an amplifier can usually solve this problem because of the improved volume and better sound quality it provides. Just make sure that you don’t abuse the use of it aka cranking it loud enough that you turn deaf to other important road signals.

They let you upgrade your sound system without changing the factory look

Thinking of giving your car sound system an upgrade but don’t want to change its factory look? A factory system upgrade that goes with an amplifier and sound-processing gear is the best way to go. Going this route lets you have a custom-designed sound system for your car without having to overhaul your interiors. 

You can also consider a compact 4-channel amplifier that can help improve the boost of your rear and front speakers. Not only are they small enough that you can easily install them behind your dashboard, but they are more economical as well. 

Things To Consider When Choosing Your Amplifier

Now that you’ve probably decided to get an amplifier, it’s time to learn all about the things you need to consider when choosing one. Read on below for some of the factors you should keep in mind before having your amp installed.

Consider the speaker-level input

The speaker-level input is one of the top elements you should take a look at in an amplifier. Amplifiers of this type are perfect if you’re searching for something that’s easy to install since they don’t require any extra electronic components to set-up. You will only need basic tools like a wiring kit, speaker wire, battery terminals, a capacitor, and hardware for power distribution. 

Required power

Additional amplifiers will obviously require more power than a factory set-up. One of the things you have to consider in relation to this is the RMS power rating which indicates the capacity of the amp to play at its fullest. To make sure that you choose the right RMS, look for one with a max RMS that doesn’t go beyond each of your speaker’s highest RMS rating. 

Another thing that you should consider is the type of car you drive. If your vehicle is compact, an amp with a smaller number of channels (e.g. 50-watts) may be enough to improve the sound clarity of your music while and cover usual road noises. If you drive a larger vehicle and is after volume, however, then it is suggested that you go for higher watts RMS channels. A 10 watts upgrade usually doesn’t make much difference too so make sure to consider this is you’re planning to go higher. 

Number of channels

The next question you’ll have to ask is: “how many channels should I have?” For those of you who aren’t that familiar yet with how amplifiers work, each of its channels serves as its source of power which then powers a speaker. The number of channels in your choice of amp, therefore, will depend on your speaker requirements. 

Consider the connection to your receiver

An amplifier with a direct connection to a receiver is the best choice if you want to keep the quality of your sound intact. Units that do not go with preamp outputs don’t offer the same clarity because you need to use speaker wires from each speaker to your receiver which, in turn, can cause a downward bump in the quality of the sound. 

Upgrading your car’s amplifier, contrary to what some people think, is a very worthy investment. It’s for everyone who likes to improve their driving experience⁠, something we all need once we are on the road. As long as you choose the right amplifier, this upgrade might be one of the best things you can do for your vehicle.
