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.
Trim the RED wire (power cable) within
18" of the battery and stripl/2"of
insulation
from the
end of the wire. Cut the wire loop that is attached to the fuseholder
in half and splice the fuse
into the power line using appropriate
inline connectors.
Use the section of cable that was
trimmed
earlier and connect
it to the other end of the fuseholder.
Strip l/2" from the battery end of the power cable and crimp a large ring terminal
to the cable.
Use the ring terminal
to connect to the battery positive terminal.
DO NOT install the fuse at
this time.
Prepare the BLACK wire (Ground cable) for attachment
to the amplifier
by stripping
l/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 a ring connector.
Fasten the cable to the chassis using a non-anodized
screw
and a star washer.
Prepare the REM turn-on wire for connection
to the amplifier
by stripping
l/2" of insulation
from
the wire end. Insert the bared wire into the REM terminal
and tighten the set screw to secure the
cable into place. Connect the other end of the REM wire to a switched
12 volt positive source.
The switched
voltage is usually taken from the source unit's accessory lead. If the source unit
does not have this output available,
the recommended
solution
is to wire a mechanical
switch
in line with a 12 volt source to activate the amplifier.
Securely mount the amplifier
to the vehicle or amp rack. Be careful not to mount the amplifier
on cardboard
or plastic panels. Doing so may enable the screws to pull out from the panel due
to road vibration
or sudden vehicle stops.
Connect the source signal to the amplifier
by plugging the RCA cables/high
level inputs into the
input jacks at the amplifier.
Connect the speakers. Strip the speaker wires l/2" and insert into the speaker terminal
and
tighten the set screw to secure into place. Be sure to maintain
proper speaker polarity.
DO NOT
chassis ground any of the speaker leads as unstable operation
may result.
10. Perform a final check of the completed
system wiring to ensure that all connections
are
accurate. Check all power and ground connections
for frayed wires and loose connections
which could cause problems.
NOTE: Follow the diagrams for proper signal polarity.

CAUTION:
These
amplifiers
are not recommended
for impedance
