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.
