Description: - Divider is a circuit within the speaker device, different bands (treble, bass) sound signal to distinguish, respectively, to the amplification, and then sent to the corresponding band of speakers and then replay. - The workmanship is fine and the material is very exquisite, with a little error of 3%. The process is much more difficult than a core inductor core inductance. - The PCB base plate adopts the fireproof board only, it is clear and clean, the corner of the circuit is rounded, and the thick copper layer can withstand more current. - The low frequency part reaches the output port through inductance, so as to achieve clear and full effect. The design is reasonable, the appearance is exquisite, and the sound quality is improved. - A wonderful tool for you to use this amplifier on your car, motorcycle, golf cart and other places, where you need small amplifier in order to have a better listening experience.Specification: - Material?Alloy - Size: Approx. 86 * 63* 25 mm / 3.39 * 2.48 * 0.98 inch - Maximum power: 160W - Frequency response: 45Hz?20kHz - Applicable impedance: 4?8? - Applicable: 10 inches speakers or less (including 10 inches)Package Includes:2 Pieces Frequency DividerNote:Please allow slightly difference due to manual measurement.
