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 a precise fit at a later 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 fuse holder under the hood and
ensure connections are water tight.
3. Trim the RED wire (power cable) within 18" of the battery
and splice in a inline fuse holder (not supplied). See
Specifications for the rating of the fuse to be used. DO NOT
install the fuse at this time.
4. Strip 1/2" from the battery end of the power cable and crimp
an appropriate size ring terminal to the cable. Use the ring
terminal to connect to the battery positive terminal.
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 bare wire into the GROUND 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.
NOTE: Keep the length of the BLACK wire (Ground) as short as
possible. Always less than 30".
6. Prepare the Remote turn-on wire for attachment to the
amplifier by stripping 1/2" of insulation from the end of the
wire. Insert the bared wire into the REMOTE terminal and
tighten the set screw to secure the wire in place. Connect
the other end of the Remote wire to a switched 12 volt
positive source. The switched voltage is usually taken from
the source unit's remote amp on 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.
NOTE:
When utilizing high-level for input signal the auto turn-on
feature is active. With the auto turn-on active,
an output to turn on/off up to two additional amplifiers or other
accessories.
7. 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.
8. Connect from source signal by plugging into the RCA
input jacks at the amplifier. The input sensitivity ranges
from 150mV-12V to accommodate signal from either high-
level(speaker) to low-level (RCA).
NOTE: All "ACTIVE" inputs must have quick connectors
connected. Switch in 2CH. position,"ACTIVE" - Front channel
inputs only. Switch in 4CH. position,"ACTIVE" - All Front and
Rear channel inputs. Be sure to route front and rear RCA cables
tightly together.

Always ensure power is off or
disconnected at the amplifier before
connecting input cables. Failure to do
so may cause damage to the amplifier
and/or connected components.
9. Connect the speakers. Strip the speaker wires 1/2" 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. Install inline fuse
near battery connection.
NOTE: Follow the diagrams for proper signal polarity.
This amplifier is not recommended
for impedance loads below 2-Ohm
stereo/4-Ohm bridged.
