Crossover is a tool that serves to limit the "frequency range" to be received by the speaker . Crossover is used to regulate flow to the tweeter, the midrange, midwoofer, and bass to the subwoofer. There are two kinds of crossover, the crossover passive and active crossover . passive crossover   Passive crossovers work after receiving the output of the amplifier, are ineffective because they are throwing power amplifier , because the passive crossover frequencies have been processed in the "boost" (increase) by the amplifier. active crossover   Active crossovers work so signal generated by the head unit (pure signal), dividing it in accordance with the desired frequency boost later in the amplifier, so that the amplifier to work more efficiently, and frequencies produced more organized in accordance with their respective purposes, tweeter, midrange, woofer , subwoofer. A little short in the use of an active crossover is the use of 12V power, ground, and remote. I...

Series 150W Amplifier With Active Crossover Series 150W Amplifier with Active Crossover is very interesting. Actually, this circuit uses 4-channel power amplifier chip. Well, as an Active Crossover here we use also a chip that can separate the tone of the bass, midrange and treble, the output from the Active Crossover can be directly amplified by power amplifier. Power Chip 4-channel amplifier that we use is SANYO LA47536 who have power outputs up to 150W, while for Active Crossover (Active Crossover) we use the LF353 from National Semiconductor.
