What To Consider When Looking For The Best Car Amplifiers For Bass

1- Budget

What is your budget? Finding the best car amplifier brand is not costly. However, we can’t deny one fact that you will need to be a little generous with your wallet for you to find.

Budget is, therefore, an important factor that you will need to consider before you go shopping for the best car amplifier for subwoofer. High-end amplifiers will be expensive but still will not guarantee performance. You can find moderately cheap amplifiers that outshine these amps. That means that there are other things that you will still need to consider.

2- Channels

Channels are the output power feeds that the sound amplified will pass through to the specific sound drivers being pushed. The number of channels depends on the number of components to be driven. These components are speakers, tweeters, and the subwoofers. If you are planning to drive more components, it means that you will need an amplifier with more number of channels.

In regards to channel number, car amplifiers can be classified into the following options;

  • Mono: Since bass is always mixed in mono, an amplifier of this type is the best amplifier for the subwoofer and for driving bass power. They are best suited for amplifiers. The speakers will still work of course, but they won’t be receiving any power from the amplifier.
  • 2-channel: These are the best for powering both the subwoofer and a pair of speakers. If you have more than a pair, you will need a high channel amplifier.
  • 4-Channel: Excellent for powering a subwoofer and two pairs of speakers. If you are now running only a pair of speakers, you can always bridge until you add more speakers. There is always room for better upgrade. They may also be expensive in comparison to 2 and mono-channel amplifiers.
  • 5-channel: Five channel amplifiers are high power consuming and expensive amplifiers suitable for a car with a component audio system with speakers, tweeters, and speakers. One channel will be dedicated to subwoofers and the other four will be dedicated to 2 pairs of speakers and tweeters.

3- Impedance

This is the second most important factor that you will need to consider while looking for the best car bass amplifiers.  Impedance is the most important feature to use when matching your amp to your speakers. Impedance represents the amount of load the amplifier is able to carry.

Try to match the total impedance of your subwoofer and speakers with one of your amplifiers. You can watch this video for more information.

4- Installation procedure

Installation plays an important role in determining the abilities of your amplifier. You will need to consider the space available. Constraining your amplifier to a small space might cause breathing problems which may result in overheating.  

You may need to hire an audio professional for installation. There are many DIY guides that can enable you to successfully install your amplifier. An example is this video.

Now you know some of the factors to consider before buying the best car audio amplifier. We have compiled a list of the top 10 car amplifiers for.
