Mounting

When selecting a location to mount your Kicker amplifier be
sure it is structurally sound and that there are no items
behind the area that could be damaged by the screws. Check
for wiring, brake lines, fuel lines, gas tanks, etc.

All amplifiers generate heat under normal operation. Be sure
to choose a location that allows adequate ventilation for the
amplifier. Also consider that the air temperature inside an
automobile’s trunk can reach upwards of 140 degrees fahren­heit. An amplifier mounted in the trunk may require additional
cooling such as extra fans moving air around the amplifier’s
chassis or ventilating the trunk to exchange the hot air in the
trunk for cooler air outside. If possible, mounting the amp in
the passenger compartment will allow cooler operation.

Remember that the controls on top of the amp will need to
be accessible for adjustment later. Keep this in mind as you
choose your amplifier’s mounting location.

Now that you are ready to mount your amplifier, use the
supplied 3mm allen wrench to remove the amplifier EndKaps.
This will give you access to the mounting holes in the amplifi­er and all wiring connections.

See Fig. 1

e

e

With the EndKaps removed, you now have access to the
four mounting holes in the mounting feet and all wiring
connections. Drill 4 holes using a 7/64” drill bit and use the
supplied #8 screws to mount the amplifier.

End Panel Views

The BLAST Port is used to connect the Remote Bass Level
Controller and for transferring control signals from one SX
amplifier to another SX amplifier. An RJ45 cable is required to
connect the BLAST Port (Out) of one amp to the BLAST Port
(In) of another. This is only required if you want to control
more than one amplifier with the same Bass Level Controller.
More details on this further in the manual.

The speaker terminals are custom-machined connectors
with full protective shrouds and are designed to accept heavy
gauge speaker wire assures maximum power transfer and
damping with minimal power loss.

Gold-plated RCA input connectors and

PAST

jacks provide

solid input and output connections for your pre-amp signal.

Custom-machined power block accepts up to a 2 Ga wire
for both power and ground connections and up to an 8 Ga for
remote turn-on assures maximum power transfer with
minimal loss.

On-board fusing (number of fuses vary by amp size) to
protect amplifier against over current conditions and reverse
polarity.

Power LED indicates amplifier is powered up and operating.

Check Fuse LED indicates a fault with the end panel fuses.
This could be fuses which are not seated properly, faulty fuses
or blown fuses.

Wiring

Signal is input into the amplifier using the low level RCA
input connections. If your source unit does not have RCA
output connectors you will need to use a Hi-Lo level signal
adapter. See your Kicker dealer for more details on this.

The output (PAST) RCA jacks provide an unaltered signal
output to feed another amplifier or component.

The use of twisted pair interconnects is recommended for
all installations to minimize noise. When routing these cables
through the automobile, try to keep them away from factory
wiring harnesses and other power wiring. If you need to cross
any of this wiring do so at a 90 degree angle to reduce the
possibility for noise problems.

When working with power connections it is always recom­mended that you disconnect the battery to prevent accidents.

The ground should be connected to the amplifier first
before making any of the other connections. This wire should
be as short as possible (24 inches or less) and connected to a
paint/corrosion free solid metal area of the car’s chassis. Use
the same gauge wire as recommended for the amplifier’s
power connection to the battery. Adding an additional ground
wire between the car battery’s negative post and the car chas­sis of this same gauge (or larger) is also recommended.

If you ever need to remove the amp from the vehicle after
it has been installed, the ground wire should be the last wire
disconnected from the amplifier, just the opposite of when
you installed it.

A fuse must be installed within 18 inches of the battery to
protect the power wire feeding your amplifier. This fuse
should be of at least the same value used in the amplifier but
no higher than the capacity of the power wire. See the charts
below for wire size and fusing recommendations.

SX .4 Series Amplifiers

Installation

USING THE SIGNAL OUTPUT JACKS (PAST)

The Output (Pre Amp Signal Transfer) RCA jacks allow you to
send the incoming signal from the AMP 1 RCA input jacks on
one Kicker SX.4 series amplifier to another amplifier or proces­sor without the need for Y cables. The signal from the

PAST
jacks is identical to the signal fed to the amplifier via its AMP 1
RCA input jacks and is not affected by any of the amplifier’s
built-in digital signal processing.

Most head units with high voltage outputs should be capa-

ble of driving up to ten amplifiers in a chain.

If only using one RCA cable to feed signal into your SX.4
series amplifier, be sure to use the AMP 1 input on the
amplifier. The AMP 1 input will feed signal to AMP 2 and the
PAST

RCA jacks.

If your source unit has front and rear RCA outputs and you
want to enable fading, simply use an additional cable to
connect AMP 2 to your source unit.

STEREO AND BRIDGED SIMULTANEOUSLY

SX.4 series amplifiers are capable of operating into a minimum imedance of 2 ohms per
channel in stereo mode and 4 ohms bridged in mono mode. AMP 1 can be bridged while
AMP 2 is in stereo OR

AMP 2 can be bridged while AMP 1 is in stereo.

These are just a few of the many ways you can use your SX.4 series Kicker amplifier.
These system diagrams are designed to give you a basic understanding of the most com­mon uses for this amplifier. For more complex systems please visit your local authorized
Kicker dealer. You can also download the SX Technical Manual from our website at
www.kicker.com for more detailed information and complex system diagrams.
