WIRING INSTRUCTIONS

The wiring of your crossover will depend on the system and speakers you are using but will either be a 2-way (bass and midrange/high) or 3-
way (bass, midrange and high) application using 2 or 4 channels of input from the car stereo.  The following pages illustrate the input and output
wiring for these types.  Please refer to the appropriate diagram for the system configuration you are using.

The power connections for this unit are made via screw tightened terminals.  Loosen the screw for the connection to be made and fully insert
the wire (strip 1/2" of insulation from the end) under the respective screw on the side panel. Tighten the screw down to secure the wire.

1. Power Connection

The battery terminal (+12V) must be connected directly to the positive terminal of the vehicle battery to provide an adequate voltage source
and minimize noise.  Connecting the battery terminal lead to any other point (such as the fuse block) may cause noise and distortion.  Use

#18

 gauge wire for this lead and connect it to the terminal of the battery after all other wiring is completed.

2. Ground Connection

The ground terminal (GND) connection is also critical to the correct operation of the crossover.  Use a wire of the same gauge as the power
connection (

#18

) and connect it between the ground terminal (GND) of the unit and a metal part of the vehicle close to the mounting location.

This wire should be as short as possible and any paint or rust at the grounding point should be scraped away to provide a clean metal surface
to which the end of the ground wire can be screwed or bolted.

3. Remote Turn-On Connection

The crossover is turned on by ap12 volts to the remote turn-on terminal (REM).  The wire lead to this terminal should be connected
to the "Auto-Antenna" lead from the car stereo which will provide the +12 volts only when the car stereo is turned on.  If the car stereo does
not provide an Auto-Antenna lead, the remote turn-on lead may be wired to an "Accessory" or "Radio" terminal in the car's fuse block.  This
will turn the crossover on and off with the ignition key, regardless of whether the car stereo is on or off.  The remote turn-on lead does not carry
large currents, so #20 gauge wire may be used for this application.

4. Input Connections

This crossover features low-level input capability.  If the car stereo has 2 channels of low-level output, connect them to the "FRONT INPUT"
jacks (see pages 4 and 6).  If the car stereo has 4 channels of low-level output, connect them to the "FRONT INPUT" and "REAR INPUT" jacks
(see pages 5 and 7).

5. Output Connections

Connect the low-level output jacks from the crossover to the low-level inputs of the amplifier(s) in the system. For 2-way systems, use the
"SUBWOOFER OUTPUT" and "MIDRANGE OUTPUT" jacks (see pages 4 and 5).  For 3-way systems, use the "SUBWOOFER OUTPUT",
"MIDRANGE OUTPUT" and "HIGH OUTPUT" jacks (see pages 6 and 7).
