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 (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 man-
ual.
When working with power connections always hook up the ground wire first and discon-
nect 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 follows:
IX 254 10Ga 10A fuse
IX 404 8Ga 30 A fuse
IX 704 4Ga 60A fuse
Any time that 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 protec-
tion 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 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, we recom-
mend that the heatsink fins run vertically as shown for
improved cooling.
For chassis isolation and to prevent engine noise from
entering your system, it is important to use the plastic
stepped washers and rubber isolators when mounting
this amplifier.
