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 KEY automatically improves the sound quality of

your vehicle with the push of a button! Breathe new

life and realism into any audio system with this small,

yet powerful, ampliﬁer and acoustic processor in one.

With simple, one-step, automatic audio calibration,

you’ll have drastically improved audio quality and

soundstage in minutes. You’ll experience symphonic

quality music whether you’re using factory speakers

of-the-art patented digital technology, to provide

the best audio performance in a vehicle. The KEY

ampliﬁer uses digital circuitry for gain-matching,

crossover frequency control, AutoEQ, Compression,

Limiter, and more, that automatically tunes your

system to audiophile performance in your vehicle. It’s

the best of all worlds, packed into a tiny powerhouse

amp that delivers our signature KICKER Performance

Installation

Mounting

Choose a structurally sound location to mount your

KICKER ampliﬁer. Make sure there are no items

behind the area where the screws will be driven.

Choose a location that allows at least 4” (10cm) of

open ventilation for the ampliﬁer. If possible, mount

the ampliﬁer in the climate-controlled passenger

compartment. Drill four holes using a 7/64” (3mm)

bit and use the supplied #8 screws to mount the

ampliﬁer.

Wiring

Disconnect the vehicle’s battery to avoid an electrical

short. Then connect the ground wire to the ampliﬁer.

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. Adding an additional

ground wire of this same gauge (or larger) between

the battery’s negative post and the vehicle chassis

is recommended. 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.

7English

The fuse should be within 18” (45cm) of the battery

and in-line with the power cable, which is connected

to your ampliﬁer. If you ever need to remove the

ampliﬁer from the vehicle after it has been installed,

the ground wire should be the last wire disconnected

from the ampliﬁer--just the opposite as when you

installed it. The KEY ampliﬁer is capable of using

the wiring directly from your head unit, but for best

results it is recommended you use power and ground

wiring from the vehicle’s battery and chassis. KICKER

recommends 8 gauge wire.

If needed, cut off the

RCA connections to

use hi-level input.

8English

For multiple ampliﬁer installations where distribution

blocks are used, each ampliﬁer should have its

proper-rated fuse, or breaker, installed between the

ampliﬁer and the distribution block within eighteen

inches of the block, or on the distribution block if it

provides for fusing. The primary power wire should

also be fused between the battery and distribution

block, within eighteen inches of the battery’s positive

terminal, with a fuse or breaker rated at least to the

sum of the individual ampliﬁer’s fuse values, but

doesn’t exceed the capacity of your wiring.

Features

DC OFFSET: The KEY500.1 automatic turn-on

mode uses DC Offset detection, which can be

selected on the end panel. Using the DC Offset

mode causes the REM wire to have +12V out for

turning on additional ampliﬁers. DC Offset turn-on can

only be used if speaker-level (hi-level) audio inputs are

being used. The DC offset mode detects a 3V DC

offset on the speaker wires when the source unit has

been turned on.

INPUT LEVEL: The RCA inputs are capable of

receiving either Hi or Low-level signals from your

source unit. If the only output available from your

source unit is a Hi-Level signal, simply press in the

Input Level switch on the ampliﬁer. Refer to the wiring

section of this manual for additional instructions.

10English

Input Gain Control with Gain Matching: The

input gain control is not a volume control. It matches

the output of the source unit to the input level of

the ampliﬁer and features Gain Matching to prevent

clipping the input. Use the KEY500.1 Gain Match

track from www.KICKER.com/test-tones with the

automatic to reach the most accurate and best

performing settings.

HI-PASS: Use the HI-PASS knob of the ampliﬁer to

set the internal high-pass crossover from 10–40Hz.

LO-PASS: Use the LO-PASS knob of the ampliﬁer to

set the internal low-pass crossover from 40–160Hz.

BASS BOOST: The variable bass boost control

on the side of the ampliﬁer is designed to give you

increased output, 0–6dB, at 40Hz. The setting for

this control is subjective. If you turn it up, you must

readjust the input gain control to avoid clipping the

ampliﬁer.

REMOTE BASS: With the optional CXARC remote

bass level control, you have the ability to control the

output level of the ampliﬁer remotely. To surface-

mount the remote bass level control, simply screw

the remote to the chosen location, then run the cable

from the controller to the “Remote Bass” jack on the

ampliﬁer panel.
