Features： 1、Wide Application: Electronic car crossover is an audio processor that can be plugged into different types of car audio systems, thus meeting a wide range of car audio needs. 2、High Class Sound: 3 way Electronic crossover divides the audio signal into three different frequency bands to provide high grade and balanced audio. 3、Different Musical Experience: The crossover is also able to enhance the musical experience with different band splitting depending on the type of music, improving musical detail and enhancing the colour of the music. 4、Enhanced Upgradeability: Speaker frequency divider offers more options for upgradeability of the car audio system, providing the user with more upgrade options. 5、Reduced Circuit Noise: Audio crossover effectively separates the incoming audio signal, thus reducing circuit noise and improving audio performance. Specification： Item Type: Electronic Car Crossover Material: ABS+aluminum alloy Number of Channels: 3 Product Description: Speakers reproduce sound based on high, low or mid frequencies. This process, known as crossover effect, occurs because most audio systems cannot adequately cover the entire frequency spectrum to minimize sound distortion and maintain an appropriate frequency ratio. Many amplifiers either have a built in 'variable' crossover so that you can set the frequency to a precise sound specification, or a 'fixed' crossover. By connecting this crossover to your amplifier, you have full control over the bass as well as the midrange and treble frequencies you want, giving you the original listening experience. Fitment: Fit for a wide range of cars Package List： 2 x 3 Way Audio Crossovers
