Top Rated and Best Amplifier for Your Car: A Buyer’s Guide


If you want your favorite 6.5” speakers to sound heavenly inside your car, you certainly have to provide them with the best amplifier widely available in the market today. For your best car speakers, it is a great move that you have the finest sounds emanate from a source highly regarded as the heart of your car’s stereo system, the amplifier.

A car amplifier is the heart and soul of a downright enjoyable car speaker system and pairing it with similarly lively subwoofers creating the best sound quality possible. We have assembled a list of 5 of the world’s most popular amplifier brands and we are just glad to tell something about them, but first, have a look at some facts about car amplifiers.

What is a car amplifier do?

Just like any other type of amplifiers, a car amplifier boosts electrical signals across your car’s speaker system. Although much smaller than home amplifiers as car dashboard space is often limited, a car amplifier has similar functions. Concerning basic car audio, the amplifier handles low-power output signals from radio, CD player, and other auxiliary connections, and boosts the electrical signals up to the point that it can power up subwoofers and car speakers.

How to match an amplifier with a speaker

What matters most in car audio is the power ratings (3). The aim is to match the power handling capacity of your amplifier with the power of your speakers or subwoofers. As the rule of thumb would suggest, the RMS power should be considered as the true power and nothing else, as other “power” is mute and almost useless when comparing them within the system.

Find out below our in-depth explanation of the different types of power concerning audio systems.

  • RMS (Root Mean Square) Power Ratings

As one of the most used “power” term in the audio system, the RMS power rating is the continuous power that an amplifier could sustain, or a speaker can drive. The RMS power rating is also considered as the most accurate representation of the statistical measurement range of various quantity and is addressed to the voltage or current passing through the audio system.

Although the RMS power has its imperfections and inaccuracies, it is still the real depiction of the continuous power so far as the industry is concerned.

Max or Peak Power Rating

No matter how you put it, the Max or Peak power rating is the amount of power an amplifier or the speaker could handle in a short (or abrupt) burst without damaging the system. It should not be confused with the RMS, as it is described as the continuous power, while the Max or Peak is the “instant” power in a short period of time.

How to choose the best car amplifier

Now you know some basic facts about audio systems, it is now time to make a decision in picking the right amplifier for your car, with these criteria:

  • RMS Power Rating

Pick the amplifier that matches the RMS Power Rating of your speaker if you already have a pair. If you do not have at the moment, better to choose the same brand of speakers and amplifier so they match perfectly.

  • Best sound quality

Choose the one with the best sound quality and not just the bass. You are certainly making your car as your second home, in fact, you might be spending half of your adult life inside your car. It is only proper that you pick the finest sound your amp can provide while you are reminiscing memories.

  • Versatility

Pick the one that could provide the maximum convenience while you maximize the potential of your amplifier. Why choose the one that could only give you powering up a set of speakers if there is an amplifier that could utilize more than a pair? Or an additional subwoofer channel to boost the sound? These things add up to your entertainment, so why not pick a versatile amplifier?

  • Cost

And finally, weigh more about the amplifier’s cost-effectiveness and qualities when dealing with price. Not all low price brands are inferior and those high-priced ones do not necessarily have the ideal traits. Use your instincts and vast knowledge on what other reviews have to say.
