1. Find a suitable location in the vehicle to mount the crossover.
2. Bolt the crossover to the mounting surface.
3. Using the screw terminals provided, connect minimum 16 gauge wire from the power,
Ground and remote terminals. Connect the shortest possible wire to a chassis ground point. The (+)
12V connection should bemade directly tothe car battery, and theremote should beconnected to
the Remote TurnOn Lead of yourhead unit. When connectingdirectly to the battery, install a 3A
Fuse within 18 inches of the battery terminal.
4. Connect all line inputs and outputs using high-quality RCA cables.
5. Recheck all connections before powering up.
6. Set all level controls to their minimum positions and set all crossover controls, switches, etc. To
the desired frequency or position.

1. Ground Terminal (GND).
2. Remote Turn-On Terminal (REM).
3. Power Terminal (+12V).
4. Power Indicator.
5. Front ChannelInputs.
6. Parallel InputSwitch: If there are4 sets (2 pairs/ Front & Rear) RCA inputsavailable, place thisswitch in
the "IN" position.If there isonly one pair of input RCAconnectors being used,place this switch in the "OUT"
position to provideFront and Rearinput from that single pair ofRCA inputs.
(Note that theFront inputs are essentially the main inputs, thusproviding an inputto these terminals,
and properly selectionof the various switch positions wouldprovide signals on ALL of thevarious
outputs.)
7. Rear ChannelInputs.
8. Subwoofer ChannelInputs.
9. Subwoofer Input Switch: If there isno dedicated subwoofersignal available from the signal source,
place this switchin the "ON"position to provide signal at thesubwoofer output terminals. If there isa
dedicated subwoofer signalsource available forthis input purpose, place the switchin the "OFF" position.
