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. Reasonable design, high-quality electronic components ensure superb load-carrying power, long-term durability and excellent sound quality. 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. The use of high quality metal film polyene capacitance, over wave protection, resistance to high temperature line inductance and so on, no welding type, very convenient to use, no worry without tools or welder is not good. If you want your audio details to perform well, the sense of hierarchy is more distinct and prominent; choosing it is equivalent to choosing a surprise.
