- Connect the inputs of channel pair 1/2 to a suitable stereo source, e.g. a head unit
with good quality RCA cables.
TIP:
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
available from the mono sub bass output of an active crossover, whether standalone,
rolloff.

Important:
Do not be tempted to connect the hot, or positive outputs, from any source
