1. Optional Tweeter Bridge – The optional tweeter bridge was modeled
after the hand milled aluminum bridges used in the famous Rockford
Fosgate Dodge Ram show vehicle. The tweeter bridge (supplied) can
be used to achieve a coaxial type mounting configuration. This
allows the music to propagate from a single point instead of two dif-
ferent locations.
2. Rubber Surround – The durable rubber surround withstands the
extremes of the automotive environment. It also improves sound quali-
ty by reducing 2nd and 3rd order harmonics and provides wider fre-
quency response.
3. 3-Layer Glass Fiber Composite Cone – The ideal cone material would
be infinitely strong, very light and would have very high damping to
ensure great sound quality. The fanaticQ Series use a 3 layer glass
fiber composite cone that is strong, light and has high internal damp-
ing to provide excellent reproduction of sound.
4. Flat Spider – The spider has the job of centering the voice coil and
providing the rear suspension for the speaker. The fanaticQ
Component Systems use a durable flat spider to ensure great sound
with long life and durability.
5. Large 1-1/4" Voice Coil with Anodized Aluminum Former – Just like
all Rockford Fosgate woofers, all Fanatic Component System midrange
drivers use an aluminum voice coil former for more efficient dissipa-
tion of heat. Dissipating the heat is key to long life and high power
handling, so go ahead and crank it up! The voice coil in the fanaticQ
series component system is larger than the voice coil in some manu-
facturer's woofers.
6. Proprietary Cast ABS Basket – This basket has unique cosmetics and
provides a solid platform for the midrange, reducing coloration of the
sound.
7. Vented Pole Piece – The pole piece extends from the back of the
speaker into the voice coil area. The fanaticQ Component System
uses a vented pole piece to allow cool air to circulate in the voice coil
gap which allows greater power handling and increased reliability.
8. Aerovent Backplate – The curved shape of the backplate opening
reduces “huffing” noises caused during high excursions. The air mov-
ing in and out of the pole piece is handled much more quietly and
efficiently than in conventional systems.

INSTALLATION CONSIDERATIONS
Tools Needed
The following is a list of some of the tools necessary for the installation of
your speakers.
Power Drill with assorted bits #2 Phillips Screwdriver
Tape Measure Voltmeter
General
1. For safety, disconnect the negative lead from the battery prior to begin-
ning the installation.
2. Never run wires underneath the vehicle. Running the wires inside the
vehicle provides the best protection.
3. Avoid running wires over or through sharp edges. Use rubber or plastic
grommets to protect any wires routed through metal.
4. Mount the speakers/crossovers away from electrical sources (other than
the amplifier) i.e., power cables, electronic fuel pumps, vehicle com-
puters, and other potential noise sources.
5. Mount the speakers/crossovers away from areas of extreme heat or
moisture.
Speakers
1. Make sure there is an area large enough of the speaker to mount.
Warning! Failure to do this can cause damage to the speaker if the
speaker frame is bent during installation.
2. Check to see that the location is deep enough for the speaker(s) and the
location does not interfere with the normal operation of the vehicle.
3. When mounting the speaker(s) in the door of a vehicle, make sure the
speaker(s) do not interfere with either the door or window operation.
4. When mounting the speaker(s) on the rear deck of the vehicle, check
the operation of the rear hatch or trunk lid. Make sure the torsion bars
and other moving parts are not obstructed by the speaker(s) installation.
• Please refer to the Specifications section of this manual for proper
mounting diameter and depth of the speaker(s).
Crossovers (not included)
1. Make sure there is a flat area large enough for the crossover to mount.
2. For best results, mount the crossover(s) next to the amplifier for a deco-
rative finish to the installation and provide an easy upgrade (no new
wires to run) for a bi-amp Rockford Fosgate system in the future.

MOUNTING LOCATION
A solid front stage with a good image is one of the most difficult tasks to
achieve in a vehicle. No car has the optimum listening environment. This
makes proper sound staging very difficult to accomplish. Most speakers
tend to be placed where they will fit easily, as opposed to where they can
perform the best. The mounting location of your speakers will have a great
effect on the sound quality of your stereo system. The special care taken to
place the speakers will yield many hours of listening enjoyment in return.
Several important recommendations should be followed.
• Place the speakers where they have a direct path to the listening area.
• For the best integration between the
midrange and tweeter, the tweeter should
be placed less than 2" from the midrange.
(Figure 1)
• If you cannot place the tweeter less than 2"
from the midrange, then place the tweeter
more than 7" from the midrange. Placing
the tweeter 2"-7" from the midrange can
cause destructive interference (frequency
response problems) which will affect the
speaker's ability to reproduce the frequency
range around the crossover frequency of the
system.
• Whenever possible, place the tweeter directly above or below the
midrange as this maximizes the imaging (point source) capability of the
speakers. (Figure 2)

2" or less

• Sound radiated from a “point source” has the most optimum stereo
imaging because the separation of the acoustical centers between the
midrange and tweeter for each channel is at the optimum. Figure 2-A
describes a horizontal speaker alignment. In a closed environment such
as an automobile, horizontal speaker alignment can cause severe
amplitude and phase differences which will degrade not only the imag-
ing, but also the frequency response. This is due to the path length dif-
ferences between the midrange and tweeter. Figure 2-B displays a verti-
cal alignment between the midrange and tweeter. With a vertical align-
ment, the path length difference between the midrange and tweeter are
reduced to a minimum. The result is a negligible difference in path
lengths between the midrange and tweeter regardless of the proximity
of the listener to the speakers. Mounting the speaker with minimum
path length difference will ensure the best staging and imaging possible
from your audio system.
INSTALLATION
Mounting the Midrange
1. Cut the proper size hole for the midrange/woofer (refer to the specifica-
tions page for mounting diameter dimensions)
2. Place the midrange over the mounting hole and mark the location of
the screw mounting holes.
3. Remove the midrange. Drill the holes for the screws using a 1/8" drill
bit.
4. Route the wire through the hole.
5. Attach the wires and be sure to observe the proper speaker polarity.
6. Place the speaker into the hole and screw the speaker into place. Be
careful not to bend the speaker frame during this step.
7. Press the speaker grille into the mounting ring.
