Yes, it is better if you know each and every fact about car amplifiers. What it is and how it works. Amps mainly transform the sound as a wave or current through the wire to the subwoofers or the speakers. The channels work as a port and at both ends of the connector cable, there is attached a pin. You can call the amplifier an increaser too. It increases the sound and the bass from low to high. The music you’re playing with your player or pod is the music of low bass and low quality. The amplifier increases it to high and makes the sound fresh and clear. However, the amp works at an alternating current system.
