Considerations & How to Pick the Best Car Amp
Aside from the key features and advantages that you can get from an amp for speakers, there are other factors you need to keep in mind before purchasing.
It’s best to be knowledgeable in an amp’s specifications, so you’re sure that you get the best amplifier for your car. By learning these features, you won’t be wasting money and effort during your shopping.
Here are a few factors to check out:
If you’re not a sound aficionado nor a car enthusiast, the channel component of an amplifier might be something you’re not versed in.
In essence, there are six different types of car amplifiers you can get depending on their number of channels. Each type can simple differentiated through their different measurements of power.
While most amplifiers perform the same way, they can operate on differing principles. That’s why one type of amplifier channel might be better suited for you than another kind.
Learn to differentiate all six channel types below:
Mono Channel Amps
Mono channel amps can also be called Class D amplifiers. They are mostly used when you’re installing subwoofers, and have a fantastic built-in bass boost.
They are also created to process lower frequencies better which is why it’s a great amplifier for a subwoofer.
Mono channel amps also primarily use multiple transistors, either you get a lot of sounds or none at all.
However, mono channel amps are also more susceptible to distortions even with a filter present.
2 Channel Amps
Two channel amps can also be called Dual Channel amplifiers. They can handle two speakers and can create a more dynamic quality of sound much like a surround sound output.
They can also handle subwoofers easily. Dual channel amps are mostly used for full-range and component speaker systems.
They are great for trucks or vans that don’t have space since you can put them under the seat.
You can also use a dual channel amp to power a single speaker at maximum output.
3 Channel Amps
With three channel amps, you get two types of circuitry in one amplifier. This makes it a great choice if you have two full-range speakers and a subwoofer.
That’s because this type of amplifier is excellent at handling low-frequency response, and you can allow a single channel just for the subwoofer.
4 Channel Amps
Starting at a four channels amplifier, you’re getting into the more sophisticated types. Usually, four channels and above are called multiple channel amplifiers.
The best 4 channel car amplifiers can help you create a full audio arena from your speaker system. The speaker setup can be customized for a more dynamic sound experience.
5 Channel Amps
Like how a 3 channel amp works, the five-channel amp is a 4 channel amplifier with a single channel designated for subwoofers.
While the best 5 channel car amplifier can provide you with more opportunities for a better and more sophisticated setup, odd-numbered systems are notoriously hard to use.
So, make sure that you can commit to these kinds of systems before you purchase anything.
6 Channel Amps
Six channel amplifiers are rare because not many people have a use for them.
However, they are great for larger vehicles like SUVs and Humvees because they provide higher power and sound quality.
- Class of Amplifier
Amplifiers for your car can also be grouped depending on their class type. However, it’s much easier to know them by the channel type.
Nevertheless, a bit of familiarization with class types can be beneficial for you.
Here are 4 class types you might encounter:
- Class A – always on, produces clean output, low distortion
- Class AB – hybrid of Classes A and B, improves efficiency, combines benefits from both classes
- Class B – can be switched on and off, enhances efficiency, great for car audio use
- Class D – extremely efficient, great for low frequencies, great for subwoofers
Just like with car speakers, knowing the power limits of an amplifier can help maximize its use in your sound system.
You have to make sure that it matches your speakers. For example, pairing a low-powered speaker with 1000 watts up will either produce low-quality sound or blow them both up.
That’s why it’s important to take note of these features below:
Speaker Power Rating
This pertains to the range of power that a speaker can receive. You don’t necessarily have to match the amplifier to speakers at precisely 100%.
So as long as your amplifier can provide your speakers with 75% of its maximum power or at most 150%, you’ll be good to go.
Impedance can also be called ohm rating. Most car speakers will indicate a minimum ohm limit so you can easily find a matching amplifier.
Do not attempt to plug a speaker with lower impedance to an amplifier that has a higher one.
Usually, you can measure sensitivity through decibels. Not a lot of people know this, but wattage and sensitivity have a logarithmic relationship.
That means when you increase power, it would also raise the sensitivity by a particular measurement. This is a big deal if you love blasting your speakers to the highest volume.
Installing car amplifiers can be tricky, especially if it’s your first time. While it is possible to do, you will have to undergo extensive research and be open to probable mistakes.
It is still highly recommended to have your amplifiers installed by professionals instead.
Sure, you’ll be paying for labor, but it requires less effort, and there are fewer chances of screwing up too.

It doesn’t matter if you get an amp made from the highest quality of materials or if it can provide you with the highest maximum of power if it doesn’t fit your car.
Make sure to take the dimensions of both your car and the amp before buying. Remember that amp size isn’t proportional to power.
Some small amps can give you higher power than their larger counterparts.
The good news is that car amplifiers aren’t as expensive as other car audio accessories. Sure, some of them would be expensive while others will be questionably cheap.
But in general, they aren’t too costly. You can get an excellent amplifier from about $100 and above. So set a realistic budget and stick with it.
Make sure that you buy only from authorized dealers and resellers, and pay the extra bucks for a good warranty.
This will come in handy in the unlikely chance that you will need services for part replacements and even repair.
Sure, warranties add to the expense, but they could help protect you from other additional charges if you need added services.
What an Amplifier Can Do for Your Sound System
When it comes to your sound system, the two most important parts are the amp for speakers and the car speakers themselves.
While the speakers are the ones that produce the actual sound you hear, the amplifier directly affects the quality of music they can deliver.
Think of the car amplifier as your stereo system’s engine. So, it’s not hard to understand why getting an amp is critical since it’s the primary power source.
A cheap amp for your car may destroy your speakers if they’re not made from good quality and do not match.
But an amp that matches the requirements of your car speakers, then you’d be treated to the best kind of audio experience you can produce!
Advantages of Installing Amplifiers
The best car amp highly depends on your needs so it will not be the same for each person. However, there are some general advantages that everyone can experience when they buy an amp.
Here are some of the few key benefits you get with an amplifier:
- Louder Volume
When you are inside your car, you are assaulted with a myriad of sounds (whether you notice it or not).
You can hear the traffic outside, miscellaneous din, and even the car’s air conditioning and engine.
An amplifier can help you understand the music you’re playing better because of the increased volume it presents.
The amplifier greatly magnifies the overall volume so you can easily choose whether to go low or go high.
- Better Audio Quality
It’s understandable that most people are content with listening to plain music. But a car amplifier actually allows you to hear details that would otherwise be unheard.
It also helps reduce disturbances and distortions, allowing your system to produce more precise and higher quality sounds.
When you buy a multi-channel amplifier, you also increase your stereo’s adaptability. When you want to upgrade your system again, it will be easier.
That’s because the multi-channel can be updated and can have added benefits.
Your car’s sound system also becomes more efficient when used with a high-quality amp since it can improve your audio range and can maximize the power available.
Where to Mount A Car Amp
So you just got the best amplifier, car audio will be a blast from now on! Right?
Well, first you need to know where actually to place your amp before that happens.
Usually, a car stereo amp can be stashed and hooked up in your trunk. However, some amplifiers work better when stored beneath the seats.
If you’re the one who will be mounting your amp, here are a few tips you might want to follow:
- Amplifier Wiring Kit is a Must. You will need a well-rounded kit to truly help you with the wiring involved. It must have a few additional power fuses, long wiring, and such.
- Don’t Bolt It Down. Bolting down your amp will cause vibrations.
- Don’t Mount Upside Down. Mounting upside-down can trap heat and fry your circuits.
How Much Does A Car Amplifier Cost?
In all honesty, there are cheap amp brands out there. However, the efficiency of those would be harder to verify especially if they come from a lesser-known brand.
Also, good amps for subwoofer use or full-range component systems will rarely be inexpensive. But you know that they can provide you with excellent quality.
The best car amps can range from a few hundred bucks to over a thousand dollars for a premium pick. So, you really have a wide variety to choose from.
You could actually get good amplifiers for just $30! However, prices really depend on different factors like wattage, channels, and even compatibility.
The best car amplifier for your car can come from a lower-end, mid-range, or high-end series depending on the features that you will need.
So, a tip is to be sure of the key features you want and set a realistic budget to go from there.
RMS Power vs. Peak Power
These two terms are relevant when you’re looking at amp for speakers (and even for car speakers themselves).
It’s a good idea to fully understand what they mean so that you can buy the best car amplifier for you.
RMS Power is the continuous, steady power that your amp can provide given a certain period. It is what manages your more frequent wattage use.
Peak Power, also called max peak, is the total wattage your speaker can handle in bursts.
Since your speaker outputs several different electrical levels at different times, you have to make sure that your max peak can handle each sharp point in your audio.

Do You Need Amps for Subwoofer?
If you are looking to add a subwoofer to boost up the overall sound quality in your car, then choosing the best car subwoofer is only half of the equation.
The other half is to find a powerful matching amplifier to power up the subwoofer so that both can work together and provide you with the ultimate music experience.
Since low frequencies have such long wavelengths, car subwoofers have to move a lot of air.
So, if you try to connect your subwoofer directly to your car stereo, you will realize that the sound quality is sub-par at best.
Without a matching amp, your car subwoofer will refuse to work correctly.
Now, to look for the right car amplifier that suits your speaker and subwoofer can be intimidating. There is a lot of technicalities involved.
But this video will be helpful:
And, if you are looking for the best amp for subwoofer, check our list above. We’re sure you can find one that suits your needs.
Car Speakers and Stereo System
While the best car amplifiers can work wonders on your sound system upgrade, a car amplifier for your car isn’t the only equipment you need to look into.
Good amp brands can only take you so far. Aside from the best car amp, you will also need the help of fantastic, high-quality car speakers and stereo system.
And there are so many types to choose from! From types like marine-grade to sizes, knowing what speakers to get is vital for the best possible audio experience.
