You might have a nice car that takes you from one point to another. But is your car really complete without a good sound system?
In order to get great sound in your car, you need two things: a good amplifier and excellent speakers. For the sake of this article, we will only talk about amplifiers and how they are integral in producing the sound you desire. The amplifier takes the input from the audio system, enhances the input and channels the output through to high-quality speakers that produce loud and crisp sound.
The car amplifier makes you feel every bass drop, makes the lyrics crisp and clear while also increasing the volume. Once you get an amplifier for your car you will feel the difference between the old output and the new output.
Most car manufacturers install modern sound systems in their new cars so you don’t need to make an upgrade unless you really want to wake up the whole neighborhood. If you have an old car then getting an amplifier is necessary but buying one is not that easy. There are so many specifications to look at, and so many companies to consider that you can get confused and overwhelmed.
Fortunately, we are here to help you choose the best car amplifier for your car. Without further ado, here is the list of top 10 best car amplifiers.
The Best Car Amplifiers in 2022
1. Pioneer GM-D8601 Car Amplifier
Mono Subwoofer Amplifier
First up on our list is a masterpiece by a well-known company, Pioneer. The Pioneer GM-D8601 is a great option for those of you who are looking to power a subwoofer for a next to nothing cost. At just a paltry price of 100 dollars, you are getting good value for money without losing out on power. Pioneer has given 1,600 watts of power in this amplifier from which you can easily get uninterrupted 800 watts of RMS power going straight to your subwoofer. This Pioneer amplifier also allows you to adjust the subwoofer settings accordingly taking the power from 40 Hz to as much as 240 Hz. Modern amps have a built-in wired bass control module that allows you to adjust the level of bass without needing to change the output from the amp itself.
The speaker level inputs given in the amp lets you connect a head unit directly with the system without needing any adapters. The Pioneer D8601 has a 100dB SNR margin which translates to better sound delivery at high volumes. The power output can also be set to 800 watts, 500 watts or 300 watts.
If you are looking for a mono subwoofer amplifier, this is the best subwoofer amplifier to purchase considering the price.

Things to Consider Before Buying a Car Amplifier
First and foremost comes the budget consideration. You cannot make the final decision before you are sure about your budget. Car amplifiers come in various price brackets. Usually, the more expensive an amp is the better it is and the more features it has. However, sometimes that is not true. In any case, you need to set aside a certain amount of money like $100 or more. A hundred dollars cover a large number of amps so you can make a comfortable decision.
When you have set aside a decent budget you need to dive in the specifics. You need to decide the number of channels you require for your sound system. This depends on the scope of your sound system and what you are trying to achieve. There is no ‘one best car amplifier’ since everyone has different tastes and goals. In simple terms, it depends on what you are trying to power up whether you are looking to power speakers, a subwoofer or two subwoofers. The more items you include in your sound system the more channels you will need. In general, there are three main types of channel options in amps:
Mono: Such amps supply a high amount of power hence they are a great option for you if you are looking to power a sub-woofer. However, a big disadvantage is that the mono amp won’t power your speakers. They will work independently of the amp, which might work for some but not for all.
2-Channel: If you have a healthier budget you can dive into the 2-channel territory. These amps are capable of powering a sub-woofer as well as two sub speakers (door speakers). Sub speakers are smaller and do not require a lot of power output. If you have more than one pair of sub-speakers then you need to take one step up the ladder and go to 4-channel amps.
4-Channel: If you are looking for a comprehensive sound system setup then a 4-channel amp is your cup of tea. These are perfect for powering up a sub-woofer and more than two speakers. If you have more than two speakers, you can always connect them all in one by bridging the channels. 4-channel amps give you a lot of room to work with for future upgrades.
In scientific terms, impedance is the effective resistance of an electric circuit to an alternating current. You do not need to dive deep into the concept of impedance. All you need to know is that the impedance rating for both your amp and your speakers/sub-woofer should be the same. The perfect match will result in the best output for your sound system. If you are still interested in learning about impedance you can take a look at this informative video that explains the concept of impedance in detail.
When all is done and dusted, all that is left is to install the car amp to your vehicle. You need to decide if you will undertake this job yourself or look for an experienced electrician to do the job for you. Car amps are not easy to install. There is a lot of science going on there which can be confusing for an average person with no relevant experience. A professional will charge you some money but will definitely do the job perfectly. If you install the car amp incorrectly you can risk blowing up your speakers or subwoofer. Therefore, it is better to save yourself from the technical jargon and delegate the hob to a hired professional. You will save time and learn some valuable things about amps.
