Electronic connections
Connect 12V DC from a constant battery source to a +12V slip-on spade terminal
and install a one (1)amp fuse in line.
1
2
3
Connect the SX7’s GROUND to a good chassis ground, near where the unit
is mounted, or to the case of the head unit.
Connect the SX7’s REMOTE TURN-ON lead to the remote turn-on lead 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 unit’s left and right front outputs
to the left and right inputs of the SX7.
4
5
Connect stereo RCA cables from the left and right Low, Mid and High outputs
of the SX7’s to the corresponding left and right inputs of your amplifiers.
Turn the unit on, and adjust the input gain on the SX7 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). Use clip
detectors to adjust output.

Adjust each of the 7 rotary equalizer controls +/- 12 dB to acheive the desired
sound characteristics.
