What Does a Subwoofer Do?

Your smaller speakers are called tweeters, and they produce sounds with a higher frequency. So when you add a subwoofer to your car stereo, you will be able to hear more of a range of sounds in your music.

The subwoofer will take some of the burden off of the smaller speakers so that the speakers will do a better job producing higher frequency sounds in your music.

No matter what kind of music you enjoy listening to, you will enjoy a higher quality sound when you add a subwoofer to your stereo.

In addition, because the subwoofer takes some of the burden away from the smaller speakers, your speakers will last longer.

Do You Need an Amp?

Although you do not need an amp, an amp will make your music sound even better. Some head units even have amps.

The amplifier will boost the low-level audio signal and make it powerful enough.

The amp will boost the sound to make your music more clear and understandable.

It also allows you to play the music louder without any distortion. It helps the bass because the bass needs a lot of power to improve the sound and enhance your music.

I loved my car but was frustrated with my media system. So I upgraded my stereo, making silly wires and precarious phone mounts a thing of the past. The Apple Car Play stereo was so good I wanted to show more people how this could be done and truly upgrade their cars multimedia system! Founder
