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 KS speakers offer an excellent upgrade to your vehicle’s factory
sound system, delivering great full-range sound at an amazing value! Whether
dropping the KS speakers in a factory location or customizing your install,
their high-efficiency design means less power is needed to play your music,
while our use of advanced materials and construction techniques ensures
optimal performance for years to come. Designed for versatile applications
without sacrificing sound quality or aesthetics, we hope you have the chance
to combine these new, upgraded audiophile components with our all-new KEY
Smart.
Amplifiers and a KICKER sub for an audio experience you won’t forget!

Installation
Wiring
We recommend using 16 gauge (or larger) wire. The KS Speakers are rated at
4 ohms and work with any source unit or amplifier designed to operate at a 4
ohm load. Make sure your source unit or amplifier is rated for 4 ohm
operation.
Connect wiring to terminals
STANDARD STEREO WIRING
minimum impedance of 4 ohms per channel
PARALLEL WIRING
Two KS Speakers wired in parallel to a single channel Total Impedance: 2 ohms
At least two amplifier channels are needed for stereo operation (only one
channel is shown)
SERIES WIRING
Two KS Speakers wired in series to a single channel Total Impedance: 8 ohms At
least two amplifier channels are needed for stereo operation (only one channel
is shown)
Mounting
The KICKER KSC speakers are designed for free-air applications 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 with the KSC65, KSC67 or KSC69, you may need to use the included multi-purpose adapter, or modify it as such that it will fit your required screw patterns. You may also need to enlarge the speaker cut-outs and pre-drill new screw holes using a 7/64” (2.5mm) bit. Custom mounting locations will require more preparation and work. 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.
These multi-bracket adapters will help accommodate the KS speakers in factory or custom locations. You may need to cut off parts or otherwise modify these adapters to fit your vehicle or application.
