Best Amplifiers for Car Subwoofer

After a tiring week, there’s nothing like unwinding with a long drive with your favorite playlist on. Picture this: the wind in your hair, shouting out your favorite songs at the top of your lungs — it’s the perfect way to kick back and recharge! It can make a night out with your friends more fun than it already is.

However, having an average sound system can be a buzzkill, especially if you’re a big fan of songs with low basses. Having a sound system with a lousy amplifier makes your listening experience bad. So, to create a clean and powerful bass, you need to purchase the right amplifier for your car subwoofer. Buying the right compatible components is very important when upgrading your car’s sound system. Or your entire sound system might get ruined.

With JBL, Alpine, and Boss dominating the market, which one should you buy? Here’s a list of the 11 best amplifiers for car subwoofer.

Things to consider while buying an amplifier for a car subwoofer

If you buy the wrong components for your car’s subwoofer, there are high chances of losing your sound system’s true potential. So, how is the amplifier right? Here are a few points to remember when buying an amplifier for your car’s subwoofer.

Power output

Car audio systems don’t necessarily need a vast amp wattage to sound loud. But the more the merrier. However, you can still look into different variations of power output according to the size of your vehicle.

If you drive a small car, hatchback, a sports car, or a small-cab pickup, then an amp of 50 watts would suffice. If you want a louder amplifier, or if you have a bigger vehicle, then step up to 75 watts. And, if you want to maximize your sound system, get an amp of 100 watts RMS or more per channel.

Type of Amplifier

Car amplifiers are classified into different classes according to their circuit design and efficiency. The most common type of car amplifiers are class A, class AB, and class D.

Class A: These amplifiers are mostly known for their strong audio output. Despite the sound quality, they could be more energy efficient, making them a less popular choice for car amplifiers.

Class AB: This class of amplifiers provides the perfect balance of efficiency and audio quality. They are made by combining the amplifiers of classes A and B. The only con of this amplifier is potential power distortion.

Class D: They’re the most popular amplifiers out of all the classes. Class D amplifiers are highly efficient, and the sound quality is also amazing.

Bass Boost feature

A bass boost feature mainly enhances the low-frequency output of the subwoofer. You have the flexibility of boosting the bass frequency according to your liking.

The lower frequencies are typically amplified around 40 Hz to 80 Hz. This produces a deeper bass. But, just like adding bass is important, adding too much bass can potentially damage your subwoofer. It creates more noise distortion.

Remote Control feature

Having a remote control feature can be a pretty big plus point because you can easily control the amount of bass you want. And the best part is, you can do it right from your passenger seat!

However, there are a few types of remote controls you can explore. For example, you can either opt for a dedicated remote level control, a digital signal processor remote control, or a remote bass boost control. But whichever remote you opt for, we would highly recommend you always check whether there is a remote control feature in your amplifier.

Crossover filter

Every car audio system needs a crossover filter, just like an amplifier is needed. A crossover filter specifically filters the unwanted frequencies of any kind of sound that is produced.

For a car subwoofer, the crossover filter mainly acts like a low-pass filter. So, it only allows low frequencies (80 Hz to 100 Hz) to pass through the subwoofer, so it only plays bass sounds. The main speakers better handle the sounds with higher frequencies. Make sure you check the crossover filter before buying the amplifier.

Size & Ease of Installation

A handy size is always a must while looking for an amplifier. Firstly, measure and note the dimensions of your intended installation location. Then, you can buy the amplifier according to that size.

Apart from the size, make sure the overall installation process is easy. Look for amplifiers with accessible connections and installation accessories.

Does a car subwoofer need an amplifier?

Absolutely, a subwoofer does need an amplifier to hit those deep bass notes in your music. Subwoofers typically produce low-frequency sounds, which need a significant amount of power. In-dash car stereos cannot provide this power to drive the subwoofer. So, an amplifier is a must to provide this power. A subwoofer and amplifier can produce strong bass collectively, improving the overall sound quality. It would be impossible to produce without an amplifier.

What type of amp is best for subwoofers?

A mono-class D amp is the best amplifier for car audio stereos. It’s the best choice because of its efficiency, size, power handling, and low heat generation. A subwoofer needs enough power to generate the sound for perfect audio quality. And voila, a class D amp is the perfect choice for it. It can produce a lot of power without generating too much heat.

Should my amplifier be more powerful than my subwoofer?

Yes, you should consider buying amplifiers that are more powerful than subwoofers. The amplifier’s power output should equal or slightly greater than the subwoofer’s RMS. You should buy an amp that can handle 1.5x or 2.5x the power of your subwoofer’s RMS rating.

Do the amplifier make the subwoofer louder?

Yes, an amplifier can make a subwoofer louder. The main aim of an amplifier is to increase the power of the audio signal sent to the speakers or the subwoofers. An amplifier is also used for power enhancement, better control of the subwoofer, and improved sound quality.

Conclusion

In conclusion, selecting the best amplifier for a car subwoofer can seem like a pretty daunting task, but our list can make it 10 times easier.

While buying an amplifier, make sure you match your car’s requirements. Most people tend to make this mistake. The size, environment, and space of your car matter a lot when getting a new amp. Moreover, you should also keep your personal requirements in mind. For example, if you want a more powerful audio output, getting a 1-ohm stereo stable amp is better than a 4-ohm stereo stable amp. That’s how you should compare the features. However, we’ve highlighted the features very carefully, so getting the best amp would now be a piece of cake.
