LL.E.D.. POWER INDICA INDICATOR: This indicator lights up when the unit is properly powered and the source unit is turned on. 2. POWER CONNECTIONS: B+ terminal: connect to a positive 12 volt source Remote terminal: connect to remote turn-on of the radio or ignition switch when a remote turn on is not available. GND: connect to the vehicle's chassis using the same point of ground as other system components. 3. RCA INPUTS PORTS: This accepts the input signal from the source unit via RCA cables. 4. HIGH LEVEL INPUTS: This accepts the input signal through the use of speaker leads from the source unit when RCA's are not provided by the source unit. 5. HIGH LEVEL INPUTS GAIN CONTROL: This knob allows the adjustment of the input sensitivity for the high level inputs to provide maximum gain control for the output. 6. HIGH P PASS S FREQUENCY SELECTOR: By using the continually adjustable dial, you may adjust the crossover points between 60 and 600Hz for the highpass output. 7. FREQUENCY MUL MULTIPLIER TIPLIER FOR HIGHP HIGHPASS: This switch may be used to further the adjustment for the highpass crossover. Switching to the x10 position, you now have crossover points adjustable between 600 and 6000Hz for the highpass output. 8. HIGHP HIGHPASS S OUTPUT LEVEL CONTROL: Use this knob to increase or decrease the output from the CX2L to match the input level of the highpass amplifier. CX2L 9. HIGHP HIGHPASSS OUTPUT OUTPUT: This is a docking port for the RCA jacks leading to the highpass amplifiers input. 10. LLOWPASSS FREQUENCY SELECTOR: By using the continually adjustable dial, you may adjust the crossover points between 60 and 600Hz for the lowpass output. 11. 45Hz B BOOST/CUT OOST/CUT CONTROL: This knob allows you to boost or cut 6dB at 45Hz. 12. FREQUENCY MUL MULTIPLIER TIPLIER FOR LLOWPASS: This switch may be used to further the adjustment for the lowpass crossover. Switching to the x10 position, you now have crossover points adjustable between 600 and 6000Hz for the lowpass output. 13. LLOWPASS S OUTPUT LEVEL CONTROL: Use this knob to increase or decrease the output from the CF2L to match the input level of the lowpass amplifier. 14. LLOWPASS S OUTPUT OUTPUT: This is a docking port for the RCA jacks leading to the lowpass amplifiers input. S REMOTE: 15. LLOWPASS Use this jack with the optional CFR-1 remote level control for contouring the lowpass output. 16. FUSE: The 1 amp fuse protects the CX2L from damage. 17. HIGH LEVEL/L LEVEL/LOW OW LEVEL SELECTOR SWIT SWITCH: Use to select high or low level input in accordance with the input you are using. POWER CONNECTIONS Before connecting anything, be sure to disconnect the ground from your battery to prevent any damage to the audio components. All components should be hooked up before the battery is reconnected . B+ Connect to this terminal a positive 12 volt lead using the same source of power used to power your amplifiers. This should eliminate any chance of picking up noise due to voltage differences. If you decide to run the power wire for the crossover directly to the battery, be sure to add an inline fuse holder containing a 1 amp fuse at the battery in case of a short. Use a minimum of 16 awg stranded copper wire and be sure to apply grommets whenever the power wire is run through any metal wall. GND When grounding your Crossfire CX2L, locate a metal area close to the crossover that is a good source of ground (preferably the floor). Investigate the area you wish to use for electrical wires, vacuum lines, and brake or fuel lines. Using either a wire brush or sandpaper, eliminate unwanted paint to supply a better contact when grounding. Use the same gauge wire for ground as you did for the power. Terminate your ground wire using the correct size ring terminal and attach it to the bare metal using a #8 sheet metal screw. It is important for this connection to be solid. To complete the job, spread silicon over the screw and bare metal to prevent rust. REMOTE Between the power and ground is a remote turn-on terminal. This terminal must be connected to a switched +12 volt source. Typically, remote turn-on leads are provided by the source unit which will turn on and off the amplifier in correspondence with the source. If a radio does not have a remote turn-on, then a power antenna wire may be used. Yet, if neither of these leads are available at the source, a switched +12 volt supply must be used. Run a minimum of 18gauge wire from the amplifier location to the source of the switched +12 volt lead. Remember, it's best to keep all +12 volt wire ran on one side of the vehicle and away from the RCA cable. Avoid running the wire near sharp edges that may easily cut through the insulation. Connect the source to the wire. Check your connections by turning on the source. The green light will illuminate if your connections are correct. SIGNAL The CX2L has two different types of inputs: low level inputs through RCA exceptionally clean sound from a source unit that accepts RCA jacks. of speaker outputs. jacks OUTPUTS and high level inputs through a four pin modular connector. Low level inpu ts High level inputs make your Crossfire CX2L virtually adaptable to any source unit provide an through the use High level inputs should only be used when RCA outputs are not available. Low level inputs Choose the correct length and style of RCA patch cables for your needs. Better RCA's usually have gold plated connectors and multiple layers of shieldi ng for better noise rejection (consult your dealer).

Would you like to have more control, say from the front seat of your vehic le? Well then, we've the answer for you -- the optional CFR-1 remote bass level control. The CFR-1 comes in a small metal casing and includes a 20 ft. cable so you can easily mount the unit under the dash and have complete control over your subwoofers. The LED illuminates when the system is in the on position so it can be easily located at night. All this and an installation time of approxima tely fifteen minutes. Connecting the CFR-1 is easy. This kit is small enough to be mounted under the dash, in the center console, or even the glove box. Use the CFR-1 as a templat e and drill two 1/8" holes for mounting. Use the screws supplied in the kit to mount the unit. After mounting the CFR-1, run the twenty foot section of cable to the CX2L. Plug this end into the port labeled "REMOTE." Turn the lowpass level control on the CX2L up just a little from your initial setting. Enjoy the music! Now your finish ed.
