Designed as the perfect compliment to the highly popular
KICKER® IMPULSE line of moderately-priced speakers, IMPULSE
Amplifiers allow you to build a high performance car audio
system on a budget.
The myriad of features on the IMPULSE Amplifiers make it
possible for you to use any source unit to control a single
amp or bi-amp system with or without rear fill.
Features and Controls
Your IMPULSE four-channel amplifier is 2 Ohm stable in stereo mode and will
operate as low as 4 Ohms in bridged mono. For connection to the source you
have the option of high level input for use with radios that don't have RCA
outputs.
An electronic crossover is built in for convenience and allows you to select
high pass for satellite speakers, low pass for subwoofers, or bypass for full
range operation. In full range configuration the Impulse amps will operate
stereo and mono at the same time.
Separate KICKEQ™ bass and treble controls give you the ability to boost low
and high frequencies to tailor the music to your taste.
— Auto-resetting short circuit and overthermal protection circuits are
incorporated to protect the amplifier from failure due to extreme conditions.
State of the art circuitry including a MOSFET power supply and glass epoxy
circuit boards are used to ensure many years of trouble free operation.

Wiring Instructions
The preferred method of bringing input signal in to the amplifier is with
RCA cables from a quality tape or CD player. A high level (speaker) input signal
may also be used if your factory deck or r aftermarket source does not have
low-level RCA jacks.
Some of the system possibilities are shown in the System Diagrams section
of this manual.
When working with power connections always hook up the ground wire first
and disconnect the ground wire last. Never make any wiring changes with the
amplifier powered up.
The in-line fuse on the positive battery connection is to protect the wire in
the event of a short circuit. Install a fuse of at least as high of a value as the
amplifier requires within 18 inches of the battery connection. An in-line fuse
valued at 30A with 10 gauge wire are recommended for the 354xi, a 60A
fuse with 8 gauge wire for the 654xi. Note: if the wire run is much longer than
10 feet and the amplifier is being used either in 2 Ohm stereo or bridged to 4
Ohms, it is recommended to use 8 gauge wire for the 354xi and 4 gauge wire
for the 654xi. This may require a power distribution block near the amp to
adapt the wire size back down to the recommended gauge to make
connection at the amp easier.
Any time that a power wire goes through a metal panel such as the firewall,
or if there is any chance of abrasion, it is necessary to use a grommet or
other suitable form of protection to avoid shorts.
The ground wire should be as short as possible and attached to the body of
the vehicle. The ground point must be clean and free from paint and
corrosion.
To reduce the chance of noise entering the
system it is recommended that the RCA cables
be run through the vehicle separate from any
power wires.
Mounting the IMPULSE Amplifier
After determining an appropriate mounting
location which provides good air circulation and
access to the end panel controls, use the
supplied screws and washers to firmly mount
the amplifier. The amplifier chassis may be used
as a template for the screw locations. Check to
make sure that the mounting screws will not
damage any components on the back side of
the chosen panel.
If a vertical mounting surface is chosen, it is
recommended that the heatsink fins run vertically as shown at right.

Adjustments and Controls
Setting Gain Control
The gain control is provided for level matching purposes. The control does
not give the amplifier any more power by turning it up. Its purpose is to adjust
the sensitivity of the amplifier in relation to the output level provided by the
source.
Start with the amp gain set to minimum by turning the control counter-
clockwise. Turn the source level up until distortion is barely audible. Then turn
it down slightly. This will typically be at about 85% to 95% of full volume. Raise
the amplifier gain until distortion is just audible. The gain is now set correctly.
Check the level with cd/tape and tuner to make sure the adjustment is
correct for all sources.
Setting KICKEQ™ Controls
The Bass and Treble controls on your Impulse Amplifier are provided to help
tune your system for ideal sound quality. After the system is installed and the
vehicle is put back together, do a listening test with music that is typical of
the type you normally listen to.
Initially set the tone controls on the source unit to flat and turn the
KICKEQ™ controls fully counter-clockwise. Depending on your personal taste
and the speakers used in the system, you may want to increase the high or
low frequencies by turning the KICKEQ™ controls clockwise. Remember that
once the vehicle is in motion there will be an apparent loss of bass due to the
masking effect of road noise. Do not attempt to make adjustments while the
vehicle is in motion. It is safer to pull off the road to make changes.
Never change the crossover settings while the amplifier is on. A loud pop will
result which could destroy speakers or cause hearing loss.

Troubleshooting
Red power indicator off, no output:
e With Volt Ohm Meter (VOM) check:
1. +12V power terminal
2. Ground terminal
3. Remote turn-on lead
Red power indicator on, no output:
* Check RCA and connections
* Test speaker outputs with known good speaker
* Check function of source unit
* With VOM in AC volts position check RCA for signal
No output from one channel:
* Check RCA and speaker connections for that channel
* Swap RCA connections from left to right
* Swan speaker connections between channels
Yellow LED protection indicator is lit and there is no output:
Case 1: Amp is very hot
* Thermal protection is engaged. Check for proper impedance at
speaker terminals. Also check location of amplifier to ensure proper
air flow around heatsink.
Case 2: Output resumes momentarily when system is turned off and
| back on.
Short circuit protection is engaged. With VOM check for short
between speaker positive and negative, and between speaker
terminals and ground.
Alternator noise (a whining that varies with engine RPM)
* Make sure that the ground for the source is as short as possible
and connected to bare chassis metal. The stock radio ground may
not be sufficient. |
e Check RCA cable routing and condition. Keep RCA cables away from
all power wires.

WARNING:
KICKER components 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 that sound level is too loud and
may permanently damage your hearing. Please use common sense when controlling
volume!
