How To Wire Tweeters With Crossover

If you’re looking to upgrade your car audio system, adding tweeters can greatly improve your sound quality. However, wiring tweeters with a crossover can be a bit confusing if you’re not familiar with the process. In this article, we’ll guide you through the steps on how to wire tweeters with crossover.

What is a Crossover?

A crossover is an electronic device that separates the audio signal into different frequency ranges. In car audio systems, a crossover is used to direct high-frequency sounds to the tweeters and low-frequency sounds to the woofers. This ensures that each speaker is playing the frequencies it was designed to handle, resulting in a more balanced and clear sound.

Types of Crossovers

There are three main types of crossovers: passive, active, and digital. Passive crossovers are the most common and are typically included with component speaker sets. They are easy to install and require no external power source. Active crossovers require external power and are typically used in high-end systems. Digital crossovers are the most advanced and can be programmed to customize the sound to your liking.

Wiring Tweeters with a Passive Crossover

To wire tweeters with a passive crossover, you will need to first identify the positive and negative wires for each tweeter. These are typically labeled on the tweeter itself or in the user manual. Next, locate the input terminals on the crossover and connect the positive wire from each tweeter to the positive terminal and the negative wire to the negative terminal. Finally, connect the input wires from your head unit or amplifier to the input terminals on the crossover.

Wiring Tweeters with an Active Crossover

Wiring tweeters with an active crossover is a bit more complicated. You will need to connect the output of your head unit or amplifier to the input of the crossover, then connect the output of the crossover to the input of the amplifier that is powering the tweeters. You will also need to set the crossover points and levels using the controls on the crossover.


Q: Do I need a crossover for my tweeters?

A: Yes, a crossover is essential for proper sound reproduction and to protect your tweeters from damage.

Q: Can I use the same crossover for my woofers and tweeters?

A: No, each speaker requires its own crossover to ensure that it is playing the correct frequencies.

Q: What is the difference between a high-pass and low-pass crossover?

A: A high-pass crossover directs high-frequency sounds to the tweeters and low-pass crossovers direct low-frequency sounds to the woofers.

Q: Can I install a crossover myself?

A: Yes, installing a crossover is a fairly simple process and can be done with basic tools.


Wiring tweeters with a crossover may seem daunting at first, but with a bit of patience and knowledge, it can be done easily. Whether you’re upgrading your car audio system or building a new one from scratch, using a crossover will ensure that your sound quality is the best it can be. Remember to always double-check your connections and follow the instructions carefully to avoid any damage to your equipment.
