This application illustrates the basic mono bridging method for all Crunch 2 channel
amplifiers.
A MONO signal source is required, such as would be available from the mono sub bass
output of an active crossover, whether stand alone, or built into a head unit or equalizer.
Do not be tempted to connect the hot, or positive outputs, from any source
together to obtain a mono signal, as this could very well damage the output stage of that
source.
It is necessary to feed the SAME signal to both left and right inputs via a Y-adapter RCA
cable. Connect the mono speaker positive terminal to the LEFT +, and its negative
terminal to RIGHT -.

N/Afor full range operation.
If you are using the mono sub bass output of an active crossover, there is nothing
wrong with switching in the low pass filter in these amplifiers for a steeper low pass roll-off.

MONO SPEAKER
The inputs are used when the radio/CD player does not have RCA cable outputs. You can connect the radio/CD player speaker wires directly
to the amplifier via the high Level Inputs.
