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 revolutionary KEYLOC is not your standard LOC.
In addition to providing you with a preamp-level signal
for use with aftermarket amplifiers, the KEYLOC
revolutionizes audio integration into OEM systems.
The KEYLOC does this with a tuning process
that automatically detects the available frequency
response from the input signal and, if desired,
corrects factory EQ settings, creating a linear signal. It
also detects and defeats factory settings like All-Pass
filters and time delay.
This DSP-powered mobile audio multitool strips the
factory audio of coloration while attenuating and
maximizing available frequencies to achieve a full-
range signal. 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!

Features
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.
Input Level: The speaker inputs are capable of
receiving either HI or LO level signals from your
source unit. When using a HI-Level signal, simply
press the Input Level switch on the amplifier to HI.

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.
7English
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. Install a 2A fuse
between the KEYLOC and the power source. 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. 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
unit’s 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.

Testing for DC Offset: 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
voltmeter’s negative lead to the vehicle’s chassis
ground, the positive lead to the speaker wire you are
interfacing with, and set the voltmeter 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). If tools are unavailable,
please see page 16.
This simple test will determine if you need to connect
the Remote Turn-On lead to a switched +12V DC
source, or if you can depend on DC Offset Turn-On
to turn the KEYLOC on and off.

The radio must be on (a low volume setting is fine for
this test). Set your voltmeter to measure DC Voltage.
Connect one of your voltmeter’s test probes to a
speaker lead and the other probe to chassis ground.
There should be a DC voltage present on your
speaker lead. The DC Voltage must be between 2.5
and 6V DC to be able to turn the KEYLOC on. If it
is the red Remote Turn-On wire does not need to
be used. The KEYLOC will sense this DC offset to
turn on, and output +12V on its remote output (up to
100mA) to turn on your aftermarket amplifier(s).
IMPORTANT: If the DC Voltage you measure is
less than 2.5V, the KEYLOC DC offset turn on
function will not operate reliably. If this is the
case, you will need to find a +12V DC switched
circuit in the vehicle and connect the RED
remote turn-on wire to that switched circuit.
