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 404

IX 704

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.
