INSTALLATION

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 be made directly to the car battery, and the remote should be connected to the Remote Turn On Lead of your head unit. When connecting directly 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.
7. Once the system is powered up, set the volume control on the head unit to a moderate level where your normal speaking voice can be heard while the music is playing.
8. Further fine tuning of the various controls may be necessary to obtain the desired results.
9. When unsure about installation or system tuning, please consult an authorized BOSS AUDIO dealer.

CONTROLS AND OPERATION

1. Ground Terminal (GND).
2. Remote Turn-On Terminal (REM).
3. Power Terminal (+12V).
4. Power Indicator.
5. Front Channel Inputs.
6. Parallel Input Switch: If there are 4 sets (2 pairs/ Front & Rear) RCA inputs available, place this switch in the "IN" position. If there is only one pair of input RCA connectors being used, place this switch in the "OUT" position to provide Front and Rear input from that single pair of RCA inputs.
   (Note that the Front inputs are essentially the main inputs, thus providing an input to these terminals, and properly selection of the various switch positions would provide signals on ALL of the various outputs.)
7. Rear Channel Inputs.
8. Subwoofer Channel Inputs.
9. Subwoofer Input Switch: If there is no dedicated subwoofer signal available from the signal source, place this switch in the "ON" position to provide signal at the subwoofer output terminals. If there is a dedicated subwoofer signal source available for this input purpose, place the switch in the "OFF" position.
10. Front channel High-Pass frequency selector.
11. Rear channel High-Pass frequency selector.
12. Frequency Multiplier: for Front Channel High Pass Frequency selector.

13 & 14: Front and Rear Channel Slope Selectors: Move the selector switch to the 6 dB position when little or no attenuation as well as little or no separation is required between the selected frequency and the next adjacent frequency. Selected 12dB position when greater definition and/or attenuation is desired between the selected frequency and the other adjacent frequencies.

15. Subwoofer Low Pass Frequency Selector.
16. Bass Boost Level Control.
17. Bass Boost Frequency Selector.
18. Phase Shift Selector switch: Use this switch to select output phase for the subwoofer channel to provide best time alignment and stereo imaging.
19. Stereo/ Mono Switch: For selection of stereo and mono mode for subwoofer output signal.

20 & 22. Front and Rear Channel High Pass Level Controls.

21. Front Channel Outputs Terminals.

23. Rear Channel Outputs Terminals.
24. Subwoofer Low Pass Level Control
25. Subwoofer Channel Outputs Terminals.
26. Subwoofer Remote Level Control Jack: To be connected to the remote control for adjusting the output level of subwoofer output. ( Note: The remote control will adjust to the highest preset setting of the subwoofer low pass gain control.)
27. Fuse :Use only a 3AMP fuse for replacement.

TROUBLE SHOOTING
