Electronic connections

1Connect 12V DC from a constant battery source to a +12V slip-on spade terminal and install a one (1) amp fuse in line.

2Connect the SX7’s GROUND to a good chassis ground, near where the unit is mounted, or to the case of the head unit.

3Connect 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.)

4Connect stereo RCA cables from the head unit’s left and right front outputs to the left and right inputs of the SX7.

5Connect 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.

6Turn 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.

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