rienced professional
installers only!
1. Disconnect the negative cable
from the battery. Note: If the
vehicle’s radio features a
code-type security system,
make certain you know the
code before disconnecting
the battery!
2. Mount the amplifier to the
desired location using four
screws.
3. Run a minimum AWG #10
power cable complete with a
20-amp fuse (not included)
directly from the positive
+
12V battery terminal to the
desired amplifier location.
Keep the fuse to within 5" of
the battery terminal, and
before the wire runs through
any metal partition.
Note: All wiring connections
should be made either by solder-
ing with heatshrink tubing insula-
tion or with high-quality crimp-
type insulated connectors
installed with a good crimping
tool. Soldering crimp connections
is recommended to further
enhance connection reliability.
Never use wire-nuts, insulation-
displacement connectors (i.e.,
ScotchLok type), or “twist and
tape” connections. Do not use
electrical tape; it will loosen with
age and extreme temperatures.
Never leave bare wire exposed.
4. Connect power wiring as
shown in the Wiring Diagram
on page 14, using the supplied
power harness.
5. Connect the outputs from the
signal source to the appropri-
ate inputs of the amplifier
according to the Wiring
Diagram (page 14) with either
high-quality low-level signal
cables with RCA plugs, with
the supplied speaker-level
input connector, or both.
6. Connect the speakers to the
amplifier according to the
wiring diagram on page 14.
7. Turn the input sensitivity
adjustment to the 1/4 position.

“line” if you are using the line-
level (preamp) inputs.
9. Set the crossover switch as
desired.
10. Set the input mode switch to
stereo, left
+
right or right
input only operation.
11. Reconnect the negative bat-
tery cable.
12. Turn on the signal source at a
low volume level and check
for the correct output from
each speaker.
13. Adjust the amplifier gain con-
trol, using the procedure
described in the Gain

ment from your amplifier.
