How to Choose the Right Car Amplifier To Buy for 2017
Compared to buying a car speaker, buying an external amplifier might sometimes be a little more intimidating. This is most especially true if you’re a first timer. The car audio system jargon tends to be a little complicated when heard by first timers.
This is because there are lots of factors behind the technology of your car speaker and amplifier together.
If this is your first time installing an external amplifier, you might think “My car already has a built in amplifier.” Yes, it does. However, while that is true, there’s always still room for improvement. Should you want to upgrade your car audio system, we will be giving you tips on how to find the best car amplifier for you.
We will start with the basics about car amplifiers and factors to be looked into when buying one. We also included several brand reviews to help jump start your hunt.
Top 9 Best Car Amplifier On The Market
What is a car amplifier?
This a basic knowledge for the car enthusiasts and music lovers. However, for first timers, there might be lots of myths and misconceptions around it. First off, an amplifier is different from a mixer and an equalizer.
Some might boast about similar features. But then, they are three different things all together. Your car amplifier is somewhat like a boost to your speakers. It increases the electric signal that your speakers might receive. This is done by boosting the voltage of the input signal. In turn, this will also increase the power of the signal.
Again, you might want to ask. Why install another amplifier (or an external amplifier) when your car already has a built in one? The answer is, sometimes you might want or need more. The head space in your dashboard can only accommodate so much a car amplifier’s size.
This is why most of the times, built in car amps are small. Smaller amps mean smaller watts (output) and fewer channels.
What To Look for When Buying Car Amplifiers
Just as we mentioned earlier, car amplifiers might get a little tricky for first timers. You might get carried away by salespeople if you don’t have basic knowledge about car amplifiers. They can only tell you so much about car amplifiers (about your wants and needs). But nothing beats a well-equipped buyer!
So here we listed down basic things you might want to look into when buying car amplifiers. However, all of this will still, of course, boil down to your budget and preferences.
1. The car amplifier size
Size matters. Do you want to stash it somewhere in the back seat? Or your car doors? Make sure first that you’re getting the right size. Forget about good quality amplifiers if they don’t fit perfectly into your chosen slot/location.
Do not ever settle for “a little too big” or “a little too small”. It must fit perfectly. Otherwise, it will only ruin the amplifier or your car interior itself.
This is one of, if not the most important factors. Knowing how much power input or output your car amplifier has is very important. Because this is what will determine if your car amplifier is compatible with the speakers you have in your car.
Find the RMS value of your speakers first. Also, take note if you have a subwoofer separate from the speakers themselves (or a tweeter) and you want it to be powered by your amp as well.
Ideally, a car amp that can produce at least 75 to 150% of your speakers’ RMS value is already good. Remember, too little power can also bust your speakers.
3. How many channels does it have?
Take note of the channels available in the car amp as well as your sound system. Are you using a compound or a full-range sound system? Ideally, your car amp should have enough channels to accommodate your speakers. Even your newly installed subwoofer.
This is why car amps with lots of channels available are versatile. However, if your audio system is minimalist, then it’s probably okay to just stick to the traditional 2-channel amp or a mono amp.
These aren’t all of the factors. However, they cover most of the basics you need to know when buying car amplifiers. Good car speakers mean nothing if the car amp doesn’t have enough juice to empower them.
If you’re up to a long term investment, try investing in more powerful amplifiers and sturdier ones. This is what will help you get the most out of your buy. After all, buying car amplifiers should not be done in haste. If you feel like you need to know more about car amps, don’t hesitate to research on your own or to ask close friends knowledgeable in the field.

Finally, keep your car amps clean. Aside from exposure to heat or high temperatures, accumulated dust may also affect your car amps. (the circuits, wiring and all) This is especially true if your car or the car amp hasn’t been in use for a long time.
