Installation
Passenger Compartment Mounting
Mounting the amplifier
in
the passenger compartment will work
as
long
as
you provide a
sufficient amount
of
air for the amplifier to cool itself. If you
are
going to mount the amplifier
under the seat of the vehicle, you must have at least 1" (2.54cm) of air gap around the amplifier's
heatsink.
Mounting the amplifier with less than
1"
(2.54cm)
of
air gap around the amplifier's heatsink
in
the
passenger compartment will not provide proper cooling and will severely affect the performance
of the amplifier and
is
strongly not recommended.
BATTERY AND CHARGING
Amplifiers will put
an
increased load
on
the vehicle's battery and charging system.
We
recommend checking your alternator and battery condition to ensure that the electrical system
has enough capacity to handle the increased load
of
your stereo system. Stock electrical
systems which are
in
good condition should be able to handle the extra load of any Lightning
Audio amplifier without problems, although battery and alternator life can be reduced slightly.
To
maximize the performance of your amplifier, we suggest the use of aheavy duty battery and
an
energy storage capacitor.
WIRING THE SYSTEM
tCAUTION:
If
you do not feel comfortable with wiring your new unit, please see
~
your local Authorized Lightning Audio Dealer for installation.
Lh
CAUTION: Before installation, disconnect the battery negative
(-)
terminal
to
prevent damage to the unit, fire and/or possible injury.
tCAUTION: Avoid running power wires near the low level input cables, antenna,
~
power leads, sensitive equipment or harnesses. The power wires
carry substantial current and could induce noise into the audio
system.
1.
Plan
the wire routing. Keep
RCA
cables close together but isolated from the amplifier's
power cables and any high power auto accessories, especially electric motors. This
is
done
to prevent coupling the noise from radiated electrical fields into the audio signal. When
feeding the wires through the firewall or any metal barrier, protect them with plastic or rubber
grommets to prevent short circuits. Leave the wires long at this point to adjust for aprecise
fit at alater time.
2.
Prepare the
RED
wire (power cable) for attachment to the amplifier by stripping 1/2" of
insulation from the end of the wire. Insert the bared wire into the
B+
terminal and tighten the
set screw to secure the cable
in
place.
NOTE: The B+ cable MUST be fused 18" or less from the vehicle's battery. Install the fuseholder
under the hood and prepare the cable ends
as
stated above. Connections should be water
tight.
3.
Trim
the
RED
wire (power cable) within 18"
of
the battery and strip 1/2"of insulation from the
end of the wire.
4.
Strip 1/2" from the battery end of the power cable and crimp alarge ring terminal to the
cable. Use the ring terminal to connect to the battery positive terminal. DO NOT install the
fuse
at
this time.
5.
Prepare the BLACK wire (Ground cable) for attachment to the amplifier by stripping 1/2" of
insulation from the end of the wire. Insert the bared wire into the
GND
terminal and tighten
the set screw to secure the cable
in
place. Prepare the chassis ground by scraping any paint
from the metal surface and thoroughly clean the area of
all
dirt and grease. Strip the other
end of the wire and attach aring connector. Fasten the cable to the chassis using anon-
anodized screw and astar washer.
