Mounting
Find a sturdy secure area to mount the CFQ31M. Be sure it is accessible, but not in an area where the equalizer
sliders or any other adjustments may be accidentally altered. Use the faceplate of the CFQ31M as a template and
mark the location of the mounting holes with a pen or pencil. Remove the unit from the mounting location to pre-
drill the mounting holes. Use large enough screws to mount the equalizer tightly in place.
Power Connections
Before connecting anything, be sure to disconnect the ground terminal from your battery to prevent any damage to
the audio components. Leave disconnected until all components are hooked up and the system is ready to play.
Remove the Molex power plug from the CFQ31M before fastening the wires into the correct slots as a precaution.
Make sure to you are looking at the terminal with the set-screws facing
upwards
while following the instructions
(see diagram).
B+
The first slot from the left is the
B+
or positive 12volt terminal. Connect to this terminal a positive 12volt lead using
the same source of power used to power your amplifiers. This should eliminate noise due to voltage differences.
Whether you decide to run the power wire for the equalizer to a power distribution block or to the battery, be sure to
protect both the stereo system and the vehicle’s electrical system from a possible dangerous short. This can be done
by placing a 3amp fuse in your power distribution block or within a few inches of the battery. Use a minimum of 16
awg stranded copper wire for this application and be sure to apply grommets whenever the power wire is ran
through any metal wall.
B-
The second slot from the left is the
B-
or ground terminal. Locate a metal area of the vehicle’s chassis as close to
the
Crossfire
CFQ31M as possible 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. The same gauge wire should be used for
ground as is for the power. Terminate the 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. Silicon should now be spread
over the screw and bare metal to prevent rust and moisture from entering the vehicle.
R
Moving on to the third terminal from the left is the remote turn-on marked
R
. This terminal must be connected to a
sw12 volt source. Most source units provide a remote turn-on lead, which are used to turn on and off all
processors in correspondence with the source. If a radio does not have a remote turn-on, then a power antenna wire
may be used.
Use a minimum of 18-gauge wire to connect the CFQ31M to the source of the sw12 volt lead. If possible,
route this wire on the same side of the vehicle as the power wire. Be cautious not to run the wire near sharp edges
that may easily cut through the insulation. Make sure all connections are secure.
DR
On the far right is the last terminal marked
DR
.
DR
is the abbreviation for delayed-remote. Connect this output to
the remoter turn-on input terminal of the amplifier. This output provides a delay of 2 seconds in the turn-on and off
to help eliminate pop or thump noises when the source is turned on or off.
Once all the wires are in place, return to the location of the CFQ31M. Cut the power, ground, and remote input and
output leads to the desired length. Strip off approximately 1/4" of the insulation on the wires. Place each wire in its
appropriate slot and tighten the set-screws securely.
