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.
In addition to providing you with a preamp-level signal
for use with aftermarket amplifiers, the KEYLOC
revolutionizes the audio installation and tuning
process by automatically detecting the available
frequency response for an input signal, and detecting
and defeating factory EQ, time-delay or single all-pass
filter.
This DSP-powered dynamo strips the factory audio of
coloration and filters, while correcting and maximizing
available frequencies. This allows you to get to the
important work of tuning your audio system with the
ease and confidence that come from knowing you’re
working with a clean signal.
With a simple, step-by-step detection and calibration
process, your aftermarket installs are about to get a
lot easier, with results you can hear!

Installation
Mounting
Choose a structurally sound location to mount the
KEYLOC. Make sure there are no items behind the
area where the screws will be driven. If possible,
mount the KEYLOC behind the dash or in the climate-
controlled passenger compartment. Drill four holes
using a 7/64” (3mm) bit and use the supplied #8
screws to mount.

Wiring
Disconnect the vehicle’s battery to avoid an electrical
short. Then connect the ground wire to the KEYLOC.
Make the ground wire short, 24” (60cm) or less, and
connect it to a paint-and-corrosion-free, solid, metal
area of the vehicle’s chassis. Keep the audio signal
cable away from factory wiring harnesses and other
power wiring. If you need to cross this wiring, cross
it at a 90 degree angle. Connect your source units
speaker outputs to the KEYLOC speaker inputs.
When interfacing into factory speaker wires it is
recommended to splice and solder, If you need to
use wire taps make sure you use proper sized wire
taps to ensure a solid connection.
If your head unit has a remote output you can
connect this to the remote input of the KEYLOC. If
your head unit does not have a remote output, the
KEYLOC can use the DC offset that is present on
the speaker outputs of most factory head units. To
measure for DC offset, connect your multimeter’s
negative lead to the vehicle’s chassis ground, the
positive lead to the speaker wire you are interfacing
with, and set the multimeter to ‘DC volts’. When the
source unit you’re using is on, you should see DC
voltage from between 2.5V–6V. The KEYLOC will
sense this DC offset to turn on, and output 12V on
its own remote output (up to 100mA) to turn on your
aftermarket amplifier(s).
Test the output voltage of the audio source before
selecting the input level setting. In general, if your
input signal is coming from the source unit, use the
LO Level Input Sensitivity setting. If your input signal
is coming from a factory amplifier, use the HI Level
Input Sensitivity setting. The LO range can accept
7
125mV-10V. The HI range can accept 1V – 40 V. The
KEYLOC can output up to 10V of preamp RCA level
output, adjustable with the Output Gain knob.
In the LO range, there is a 60Ω load for use with
newer smart radios that shut off their outputs if they
do not detect a speaker. If there is a need to load a
source unit that has an output voltage greater than
10V, please use the KISLOAD products instead of the
KEYLOC’s built in load resistors.
Install a 2A fuse between the KEYLOC and battery.
The fuse should be within 18” (45cm) of the power
source and in-line with the harness’ yellow power
cable, which is connected to the KEYLOC. Connect
the preamp-level RCA outputs to your amplifier.

Operation
The KEYLOC is a 2-channel DSP based active line
output converter with the following features.
Automatic Turn-on: DC offset remote input turn-on,
and remote output turn-on (100mA) to turn on other
products.
Frequency Response Correction: Smooths
frequency response of two channels from your
source unit via EQ correction. It can fix EQs with Qs
ranging from 0.5-10 with up to +/- of 12dB of boost
or cut.
Factory Time Delay Defeat: Ranging from .06mS
– 10mS, the algorithm is accurate down to .06mS.
ALL-Pass Filter Defeat: The KEYLOC can correct
up to three all-pass filters on one channel. The
All-pass filters can have a Q ranging from 0.5–3.5,
as long as they do not interact with the other All-Pass
filter’s phase.
Passive Frequency Detection: Before running the
KEYLOC setup process, it is in passive frequency
detection mode. You can use this mode to detect
what band of frequencies are available on the given
speaker outputs that the KEYLOC is connected to.

Signal Identification
The KEYLOC will help you identify the correct OEM
wires to which you should connect using the following
steps:
1. Turn the Input Gain on the KEYLOC all the way
down.
2. Turn the audio source up to at least 1/2 volume.
3. Play the Pink Noise track from
4. Turn the Input Gain up slowly until Low, Mid, and
High LEDs begin to light up.
The Low, Mid, and High LEDs will turn on to indicate
the frequency range that has been detected. They
will alternately blink for left and right channels every
half second. If both channels are the same, the
LED(s) will be solid. The LED that lights up first will be
the best application for the signal you are currently
receiving. The more gain you must add to light up the
remaining LEDs, the less signal is available for those
applications.
