Car Subwoofer Crossover 80Hz or 120Hz

If you're an audio enthusiast, you know that a good subwoofer can make all the difference in your car audio system. But when it comes to setting the crossover frequency for your subwoofer, there's a lot of debate about whether to choose 80Hz or 120Hz. In this article, we'll dive into the details of car subwoofer crossover frequencies and help you make the right choice for your setup.

The Battle of Frequencies

When it comes to car subwoofer crossover frequencies, there are two popular options: 80Hz and 120Hz. Each frequency has its own advantages and disadvantages, so it's important to understand the differences before making a decision.

1. Sound Quality

One of the main factors to consider when choosing a crossover frequency is sound quality. The 80Hz crossover is often considered the sweet spot for most car audio systems. It provides a smooth transition between the subwoofer and the main speakers, resulting in a balanced and natural sound. On the other hand, the 120Hz crossover can produce a more aggressive and punchy bass, but it may sacrifice some clarity and definition in the midrange.

2. Speaker Size

Another factor to consider is the size of your main speakers. If you have smaller speakers, such as 6.5" or 5.25" components, the 80Hz crossover may be a better choice. This is because smaller speakers have limited low-frequency capabilities, and setting the crossover at 80Hz allows the subwoofer to handle the lower frequencies, resulting in a more balanced sound. However, if you have larger speakers, such as 6x9" or 6x8" components, they can typically handle lower frequencies, and a 120Hz crossover may be suitable.

3. Music Genre

The type of music you listen to can also influence your crossover frequency choice. If you mostly listen to rock, pop, or electronic music with heavy bass lines, a 120Hz crossover may provide the extra punch and impact you're looking for. However, if you listen to a wide variety of genres, including classical or jazz, the 80Hz crossover may offer a more natural and balanced sound across the entire frequency range.

4. Personal Preference

Ultimately, the choice between an 80Hz or 120Hz crossover frequency comes down to personal preference. Every car audio system is unique, and what sounds good to one person may not sound as good to another. It's always a good idea to experiment with different crossover frequencies and listen to a variety of music to find the setting that suits your taste.


Choosing the right crossover frequency for your car subwoofer can greatly enhance your audio experience on the road. Whether you opt for the smoother sound of an 80Hz crossover or the punchier bass of a 120Hz crossover, it's important to consider factors such as sound quality, speaker size, music genre, and personal preference. By taking the time to experiment and fine-tune your crossover settings, you can achieve the perfect balance between your subwoofer and main speakers, resulting in a truly immersive and enjoyable listening experience.
