Overview
IMPORTANT SAFETY WARNING
PROLONGED CONTINUOUS OPERATION OF AN AMPLIFIER, SPEAKER, OR
SUBWOOFER IN A DISTORTED, CLIPPED OR OVER-POWERED MANNER
CAN CAUSE YOUR AUDIO SYSTEM TO OVERHEAT, POSSIBLY CATCHING
FIRE AND RESULTING IN SERIOUS DAMAGE TO YOUR COMPONENTS
AND/OR VEHICLE. AMPLIFIERS REQUIRE UP TO 4 INCHES (10CM) OPEN
VENTILATION. SUBWOOFERS SHOULD BE MOUNTED WITH AT LEAST 1
INCH (2.5CM) CLEARANCE BETWEEN THE FRONT OF THE SPEAKER AND
ANY SURFACE. KICKER PRODUCTS 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.
The KICKER ST Street-series speakers
are the latest step forward in KICKER’s
innovating line of full-range PA and mobile
speakers. The horn-loaded bullet tweeters
and 7 and 9-inch square mid-range drivers
were engineered with custom installations
and tough environments in mind. The hyper-
efficient square design of the speakers, and
compression tweeters pushed through a
horn, cut through ambient noise, crowds or
anything that comes between you and the
sound. Whether upgrading an existing audio
system or decking out a new one, these
speakers are designed to be mounted in
free air locations and get LOUD! We hope
you have the chance to combine these
new speakers with our award-winning line
of amplifiers and accesories to get the most
out of your new system!

Note: All specifications and performance
figures are subject to change. Please visit
www.kicker.com for the most current
information. To get the best performance
from your new KICKER speakers, we
recommend using genuine KICKER
accessories and wiring. Please allow two
weeks of break-in time for the speakers to
reach optimum performance.
Pro Tip: You’re a KICKER amplifier and a
few cables away from a full system upgrade
that will dominate any factory system!
KICKER line of amplifiers make it easy to
upgrade to solid bass with your existing
or stock source unit. Also, ask your dealer
about KICKER Subwoofer upgrades.
5English
Wiring Configuration
We recommend using 16 gauge (or larger)
wire. The ST Mid-range speakers are rated
at 4 or 8 ohms and work with any source
unit or amplifier designed to operate at the
respective ohm load. Make sure your
source unit or amplifier is rated at the
correct ohm load for operation.
Carefully run the speaker wire in a location
that is clear of vehicle or other mechanisms.
If factory speaker wiring is not available in
your desired location, it may be necessary
to run speaker wire through the door jamb.
The speaker wire should be kept away
from sharp edges and avoid the possibility
of getting pinched by the door. An existing
grommet in the door jamb is the ideal
place to run the speaker wire. If the factory
hole and grommet do not exist or are
inaccessible, you must drill a hole to run
the speaker wire through the door jamb. Be
careful not to drill into other wiring or existing
door mechanisms. Any time a wire is run
through a hole, it is necessary to insert a
rubber or plastic grommet to protect the
wire from damage.

Tweeter Wiring
The ST-Series Tweeters include a capacitor
for use as a passive high-pass crossover,
protecting the tweeter from low frequencies
and providing the best frequency response
for the tweeter in relation to the mids.
Install the capacitor
in-line with the
tweeter’s Positive
speaker input wire as
shown.

If the tweeter output is too loud, install the
capacitor and resistor in series with the
tweeter’s Positive speaker input wire as
shown.

Speaker Mounting
The KICKER ST Speakers are designed for
free-air applications in custom installations
and do not require a sealed enclosure for
optimum performance. It is important to
isolate the sound coming from the front of
the speaker from the sound radiating from
the back of the speaker. This is most easily
accomplished by mounting the speakers in
a vehicle’s factory locations or in a location
with a semi-isolated rear chamber (like the
rear deck of a car behind the rear seats).
If you are replacing factory speakers in
their original locations, you will likely need
to modify the mounting hole as such that
it will fit the speaker and required screw
patterns. Use the included mounting hole
cutout templates. You will need to pre-drill
new screw holes using a 7/64” (2.5mm)
bit. Make sure that the speaker will not
interfere with trunk and door opening and
closing mechanisms and that the enclosed
screws will not puncture the fuel tank,
puncture wiring, or interfere with any other
mechanical parts on the underside of the
mounting surface. Cycle the windows all the
way down and up.

If the speaker cut-out locations require you
to cut metal, avoid structural metal and
braces. If the door body and panel cannot
support the weight of the speaker, an
optional reinforcing ring made of suitable
material may be fastened or adhered to the
door body.

Tweeter Mounting
The tweeter may be through-mounted
behind the mounting surface, or surface-
mounted on top.
For Through-Mounting, cut a circular
hole in the mounting surface at 1.75”
(45mm) for the ST3TW, and 2” (50mm) for
the ST4TW.
Choose a flat location on the panel with
space behind the panel to allow room for
the motor structure, and tweeter. After
checking the clearances, cut a mounting
hole in the panel.
Install the Backing Nut onto the tweeter.
10English
Place the tweeter in the mounting hole
and install the Round or Square Mounting
Flange onto the Tweeter, orienting the
tweeter and flange as desired.
Tighten the Backing Nut towards the
mounting surface to secure the Tweeter.
