Wiring
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. It is not recommended to mix high and low level inputs. Engine noise in the system will
probably result.
ome 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. For the Kicker Impulse IX406 amplifier a fuse value of 60A and 8 gauge power wire are recommended.
If the power wire is longer than 10 feet, it is recommended that the wire size be 4 gauge to reduce losses.
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 at least 8 gauge, as short as possible and attached to the body of the vehicle. The
ground point must be free from paint and corrosion.
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 amplifi-
er.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 compo-
nents on the back side of the chosen mounting
surface.
If a vertical mounting surface is chosen, we rec-
ommend that the heatsink fins run vertically as
shown for improved cooling.
