Specification: Item Type: Electronic Car CrossoverMaterial: ABS+aluminum alloyNumber 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.
