Stereo Power Amplifier
Congratulations! You have just purchased one of the latest in a long line of
exceptional car audio power amplifiers from Stillwater Designs. Your KICKER
Impulse was designed and engineered by the same team which created
many other international award winning KICKER components like the ZR, ZX,
and XS-Series amps. It contains a number of cutting-edge features to give
you outstanding performance and dependability when installed in a properly
designed system.
Thanks for buying KICKER. Enjoy.
KICKER IMPULSE AMPLIFIER FEATURES
Two sets of RCA jacks on each Kicker Impulse amplifier allow you to build multiple
amplifier systems without having to use RCA splitter cords to distribute the signal. Now
it is simply a matter of bringing one set of RCAs into the first amplifier, then using the
output RCA jacks as a feed to the next amplifier.
Amplifiers are stable at 2 Ohms stereo and as low as 4 Ohms in mono.
Input connections are included for high and low level signals for use with radios that
have either RCA or speaker level 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 Kicker Impulse amplifiers will operate stereo and mono at
the same time. |
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 MOSFET power supply and glass epoxy circuit
boards are used to ensure many years of trouble free operation.

Wiring the KICKER Impulse Amplifier
The preferred method of bringing input signal in to the amplifier is with RCA
cables from a quality tape or CD player. A high (speaker) level input signal may also
be used if your factory deck or aftermarket source does not have low level RCA
jacks. Regardless of which input is used the output RCA jacks on your Kicker
Impulse amplifier will provide a low level signal for multiple amplifier configurations.
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 chassis mounted fuse(s) are in place to protect the circuitry of the amplifier
in the event of major trouble. An in-line fuse must be installed within 18 inches of
the battery to protect the power wire used to supply current to the amplifier. This
fuse has to be at least as high of a value as the amplifier is supplied with. In-line
fuse and recommended wire size are as folows:
IX 2302 4Ga 80A fuse
IX 1302 6Ga 50A fuse
IX 702 8Ga 30A fuse
IX 402 10Ga 20A fuse
IX 252 12Ga 10A fuse
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 free from paint and corrosion. Use the same
size wire for ground connection as is used for power.
Mounting the KICKER 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 can 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 mounting surface.
If a vertical mounting surface is chosen, it is
recommended that the heatsink fins run
vertically as shown for improved cooling.

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
The LED mounted on the end panel of the amplifier lights up in two different
colors depending on the condition of the amplifier. Green indicates that the
amplifier is turned on and no trouble exists. When it turns red this indicates that
the protection circuit has been engaged. The LED on the top of the amplifier
chassis indicates that the amplifier is on. When the protection circuit is engaged,
this LED turns off.
Green power indicator off, no output:
* With Volt Ohm Meter (VOM) check:
1. +12v power terminal
2. Ground terminal
3. Remote turn-on lead
Green 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
* Swap speaker connections between channels
Red 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.
e 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.
* Check RCA cable routing and condition. Keep RCA cables away from
all power wires. |

KICKER components are capable of producing sound levels that can permanently damage
grow hearing! Turning up a system to a level that has audible distortion is more damaging
E your ears than listening to an undistorted system atthe same volume level. The threshold
J of pain is always an indicator that the sound level is too loud and may permanently
EEE damage your hearing. Please use common sense when controlling volume!
