QUALITY CONTROL:
In-house construction of critical components like transformer and chassis,
as well as total assembly, allows
LINEAR POWER™
to maintain uniform quality.
100%
of the
finished units are tested then burned in for four hours and tested again. Amplifiers that pass this
rigorous test have truly earned the
LINEAR POWER™
logo. All
LINEAR POWER™
amplifiers
are designed and hand assembled in house and built totally in the
USA
.
MOUNTING
1.
The amplifier will work best if it is kept as cool as possible. Mount in a position that would allow
the circulation of air. Mounting the amplifier so that the heat sink fins are vertical provides
convection air flow and provides the best cooling option. If mounting the amp horizontally, you
should provide a minimum of 2 inches of overhead clearance above the amplifier for heat to rise
from the heat sink. If using the optional fan shroud, be sure not to block the intake side of the fan
and also allow the exhaust side to blow freely into an open area.
2.
Wire all connections as shown in instructions. If using the optional fan shroud or your own fan
system, connect fan power plug to the amp. Place fan shroud into position over amplifier and
mount securely.
3.
When mounting the amplifier
DO NOT
allow the case (heat sink) of the amplifier to come in
contact with any other metal or chassis ground of the vehicle. Doing so can result in system noise
resulting from a ground loop created from the secondary ground connection between the case of
the amp and the body of the car. Use the amp’s mounting holes and the installed rubber
grommets to mount the amplifier securely and insulate it from other metal and ground. If any of
the grommets are ever damaged, replace them with new grommets. Installing the amplifier on an
amp board or in an amp rack to further isolate it from the vehicle is recommended.
WIRING
1
. Disconnect the
negative ground cable
from your vehicle's battery before making any power
connections and/or pull
MAIN power fuse
at battery for audio system.
DO NOT
reconnect main
system power fuse and/or ground cable until installation is complete!
2.
DO NOT
connect RCA inputs to amp until all other wiring is finished
. This will protect
radio RCA grounds from damage from 12 volts possibly shorting to case of amp and thru to RCA
cable grounds and into head unit!
DO NOT
disconnect or re-connect RCA cables when amp
is on.
(See
RCA GROUND
section on
page 4
)
3.
Connect the negative ground wire from the amp to a solid frame member via bolt or self-
tapping screw. This connection must be to a clean, unpainted surface. Always attach the ground
wire first when installing this amplifier and disconnect the ground last when removing this amp
from the system. Ground cables must be of the same size as power since DC is a loop condition
and the same amount of current is passed thru the ground as is the power.
4.
Fuses of the proper size
(1 x 20 ATC)
must be installed internal of the amp to protect the
vehicle's electrical system and the amplifier from damage. There should be a master system fuse
installed within 18 inches of the car battery to protect the battery and power cable in case there is
a wiring short between the battery and the amplifier(s). This master fuse should be connected to
the battery's positive terminal and should be of a large enough size to provide needed current to
all amplifiers without limiting current to the system. (i.e., the fuse should be larger than 40 amps.)
The power connection block on the end of the amplifier will accept up to 4 gauge cable, a
minimum of 6 gauge power and ground is recommended.
WARNING: USE OF OVERSIZE FUSES INTERNALLY WILL VOID THE WARRANTY
