How to Choose the Best 4” Car Speaker

A 4 inch car speaker usually has a woofer, a tweeter, and a crossover component. The crossover is responsible for switching between the woofer and the tweeter. Some 4 inch car speakers also include built-in amplifiers, which may be necessary if you have a more modern sound system with multiple speakers.

Here are some factors to consider when choosing the best 4 inch car speaker with good bass for your vehicle:

Sound Quality

This factor is extremely subjective, as what one person may consider perfect sound quality for another may not be an issue at all. However, here are some things to consider:

  • Midrange: Some people prefer speakers with a smoother midrange sound, which allows for more clarity. Others like a speaker that emphasizes the bass.
  • Highs: If you like your music to have a bit of a “pop” to it, then you’ll want to go with speakers that have a little more high-frequency energy, which is why speakers with a smooth midrange sound also tend to have a bit more emphasis on the bass.
  • Lows: If you’re looking for more “bassy” sounds, then you should consider speakers with a more pronounced low-frequency response.
  • Volume: If you’re using the speakers in your car, you may want to pay attention to the maximum volume setting. If you have an older car, it may not be able to reach the maximum level without causing damage to your car’s speakers.

Power Output

When shopping for 4 inch car speaker, it’s important to take note of the power output and how it’s rated to work with your vehicle. You’ll also want to look into the wattage of the amplifier powering the speakers. The higher the output, the louder the volume will be, which is good if you plan on playing some loud music.

Frequency Response

The frequency response of a speaker measures how wide or narrow its range of sound production is. This is important because it determines how loud or soft your car speakers can play.

It’s best to go with a speaker that has a frequency response that extends from 50 hertz to 20,000 hertz, with the highest volume occurring around 1,000 hertz. This ensures that you’re able to hear all the sounds in your car’s sound system.

Speaker Placement

There are many ways to set up a speaker system in your car, but it’s important to pay attention to the placement of the speakers. You want to make sure that they’re properly positioned and that there aren’t any obstructions between them and your stereo or amplifier.


When shopping for 4 inch car speakers, you’ll need to consider not only how much you can afford but also what you’re looking for in a speaker.


Are 4 inch car speakers loud?

They are loud enough, but you’ll need a subwoofer if you want more bass. 4-inch car speakers generally come with a 2-inch speaker driver, which produces lower frequencies. However, the quality of the sound is significantly better due to the use of higher-quality drivers.

How many speakers do you need in a car?

The number of speakers you need depends on the purpose of your audio system. In a typical car audio system, you might need a few small speakers to provide some bass, along with one large speaker to provide a stereo effect. If you have an MP3 player or CD player, then you’ll need an amplifier. And if you want your audio system to be fully functional, you might also need an FM radio tuner.


If you want to upgrade your car’s sound system, but don’t want to go too big, you should definitely consider using these 4 inch car speakers. They are very easy to install, they are cheap, and they produce amazing sound quality.

We hope this list of best 4 inch car speakers with good bass helped you find the best one for your needs.
