KICKER IMPULSE COMPONENT SYSTEM FEATURES
With your new KICKER Impulse Component System you can expect excellent frequency
response across all but the lowest frequencies normally covered by subwoofers.
For the smoothest response at the high frequencies, a one–inch titanium dome is
matched with a neodymium magnet structure. In order to absorb back waves and provide
superior transient response, a felt damping plug is placed behind the dome. For tweeter
reliability, the voice coil is bathed in a Ferrofluid™ solution. A choice of surface or flush
swivel mounts, and our innovative Coaxial Tweeter Mounting option on the I5.2, I57.2, I6.1
& I6.2, is included to allow flexibility in placing the tweeter in the best location for sound
quality.
A seamless transition from the woofer to the tweeter is achieved with the inclusion of a
second-order 12dB per octave two-way passive crossover at 4.5KHz. This computer-aided
design also includes dual incandescent tweeter protection elements.
Woofers feature curvilinear injection molded polygraphite cones, with butyl rubber surrounds, for smooth extended frequency response. Kapton™ voice coil formers and blackened metal parts in the motor assembly provide exceptional thermal power handling capability.
Installation Instructions
KICKER Impulse Component System woofers are specifically designed for mounting in
freeair applications. While the speakers don’t need a sealed box to work in, for optimum
performance it is important to isolate the sound coming off the front of the driver from
the sound coming off the back of the driver.
This isolation is usually accomplished by using the correct size driver in a factory speaker
location. Grills are included for use in installations that mount the driver in custom locations.
The tweeter mounts separately to allow the installer to choose the best location for
sound quality and imaging. Two mounting schemes are included to allow more versatility
on tweeter location, plus a coaxial option on the I5.2, I57.2, I6.1 and I6.2.
Mounting:
The easiest mounting location for the woofers is in the front factory speaker locations.
This isn’t always available on all vehicles due to small cutouts or no stock cutout at all. If
custom door-mounting locations are desired for your drivers, be careful to avoid interference from window and/or door lock mechanisms. The first step is to find a location on the
door panel that will accept the size of speaker chosen. Now remove the door panel from
the door and check for the operation of the window all the way up and down. Also try to
avoid structural metal and braces if metal must be cut to mount the speakers.
On custom locations that use the supplied grill, mount them as indicated in
this diagram. The I57.2 and I4.2 are not supplied with grills.
The best location for the tweeter is usually high up on the door and as far forward as is
possible without interference from the dashboard. If the chosen place is flat and space
behind the door panel allows the use of the recessed mounting cup, follow the mounting
arrangement in this diagram:

(Mounting, continued)
After checking for clearance, cut a 2–1/8" hole in the door panel. Mount the recess cup
from the outside with the mounting clip on the inside of the door panel. The 8-32x1/2"
flathead screw joins the two pieces together.
If the surface mounting arrangement for the tweeter works out best, then the
following diagram shows how it works. A #8 flathead sheet metal screw is supplied to
attach the surface mount cup to the door panel.
With either of these tweeter mounting schemes, the wiring and insertion of the tweeter
are the same. The short wires attached to the tweeter are fed through the larger hole in
the mount; then the tweeter is snapped into the mount.
If any of the drivers are mounted in the door, it is necessary to run the supplied wire
through the door jamb. This wire should be kept away from sharp edges and the possibility
of getting pinched. An existing boot in the door jamb is the ideal place to run the wires,
but sometimes this does not exist or is inaccessible. Drilling holes to run wires through is
very tricky, and caution must be exercised not to drill into other wiring or mechanisms. Any
time a wire is run through a bare hole, it is necessary to insert a rubber grommet first.
The supplied crossovers should not be mounted in the doors or any other location that
is subject to moisture. Inside the kickpanels or under the dash are ideal locations for the
crossovers in most vehicles.

Wiring
There are three sets of wires supplied with the Kicker Impulse Component Systems. One
set has two different size female connectors (.205" and .110") and is designed to plug on to
the terminals of the woofer. The other end of this wire goes to the woofer output on the
supplied crossover. Also supplied are two sets of wires with no connectors on either end.
One will go from the tweeter output on the crossover to the short wire coming out of the
tweeter; join using the supplied butt connectors. The last set of wires is used to join the
input of the crossover to the output of your source unit.

3. Place the speaker (without the grill ring) in the hole and position with
mounting screw holes straight across from each other. Mark the mounting holes
and draw a line around the top of the speaker basket.
4. Remove the speaker from the hole.
5. Drill a 1/4" hole on the line you just drew,
approximately halfway between the top two
mounting hole locations. Please note that the
position of this hole is critical; too high and it
will be visible once the grill is installed, too low
and the tweeter wire may get pinched. If there
is metal beneath the panel where this hole is to be
drilled, put a 1/4" grommet in the hole from the
back side.
6. Do the preliminary wiring by bringing the connector end of the woofer and tweeter wires within
reach inside the woofer hole.
7. Snap the tweeter into the tweeter bridge,
making sure the K logo is positioned correctly and
that the wires exit through the larger hole in the
tweeter cup.
8. Snap the tweeter bridge assembly into the grill ring.
9. Route the tweeter wires through the groove on the
back of the tweeter bridge as shown in the diagram.
10. Push the tweeter wires through the hole you drilled
in Step 5. Working through the woofer cutout (watch for
sharp edges!), connect the tweeter wires to the wires
attached to the tweeter output on the crossover using the
supplied butt connectors.
11. Connect the woofer wires from the crossover directly
to the driver.
12. After positioning the tweeter bridge/grill ring assembly on the front of the woofer, carefully place the entire
assembly in the mounting hole. Please note: at this time carefully push any extra wire back
into the 1/4" hole, making sure that the wire goes around the speaker without getting
pinched.
13. Secure the entire assembly to the mounting surface using the supplied screws.
14. Carefully push the grill in place.
15. Once your system is operational, you can experiment with swiveling the tweeters for
the best sound quality.

KICKER drivers are capable of producing sound levels that can permanently
damage your hearing! Turning up a system to a level that has audible distortion is
more damaging to your ears than listening to an undistorted system at the same
volume level. The threshold of pain is always an indicator that the sound level is
too loud and may permanently damage your hearing.
Please use common sense when controlling volume!
