The flashing ring LED's at the front flash to the beat of the music. This is done by connecting the positive and negative of the LED's to the left and right channels of the amplifier.
The 4 ohm sub is connected to the 5th subwoofer channel. The 4 speakers are each connected to seperate speaker channels. The gain and frequency response are set at half.
The volume can be controlled by a linear potentiometer. Connect the aux cord to the linear pot, then to the amplifier RCA Connections
