wiring tips
When making electrical connections to your amplifier, please observe the
following:
Connect 12V DC from a constant battery source to a +12V slip-on spade terminal and install
a one (1) amp fuse in line. (six (6) amp fuse for PLE702b case)
Connect the signal processor’s GROUND to a good chassis ground, near where the unit is
mounted, or to the case of the head unit.
Connect the signal processor’s REMOTE TURN-ON lead to the remote turn-on lead out of the
head unit, and install a 1/2 amp fuse in line. (A relay should be used if turning on more than
one component, such as EQ’s, crossovers or amplifiers.)
Connect stereo RCA cables from the head’s left and right front outputs to the left and right inputs
of the signal processor.
Connect stereo RCA cables from the left and right outputs, (and low, mid and high outputs if
applicable), of the signal processor to the left and right inputs of your amplifier(s) or additional
signal processor(s).
Turn the unit on, and adjust the input gain on the signal processor to match the output of the
head unit (1/2, or at center position, is about 1 V). Be careful not to overdrive the input of your
amplifier(s) or signal processor(s).
Adjust each of the crossover or equalizer controls to achieve the desired sound characteristics.
