INSTALLATION GUIDELINES

1. Please read this owner's manual care-

fully before installing this amplifier.

2. Disconnect the battery ground

terminal prior to making any elec-
trical connections.

3. Check for any hazards or obstruc-

tions such as gas tanks, fuel or
brake lines, and wiring harnesses
before mounting the amplifier.

4. Pick a mounting location that will

provide adequate access and venti-
lation and protect the amplifier
from heat, moisture, and dirt.

5. Avoid sharp metal areas when

routing cables to the amplifier, and
run RCA cables away from the
power cables and other potentially
noisy car harnesses.

6. The amplifier should be grounded

with a short, heavy gauge wire
connected directly to the car at a
bare metal surface, preferably

scraped body sheet metal. Do not
use factory grounded locations,
seat bolts, or brackets that are
spotwelded.

7. Always fuse your power connection

within in 8 to 10 inches of the
battery terminal. Use a fuse or
circuit breaker rated slightly more
than the on-board fuse(s) of the
amplifier(s). The gauge of power
wire used should take into account
the total current draw of the
system, and the length of the wire
used. IASCA and other auto sound
competition organizations have
charts available for this; you can
also find a chart in the MECP study
guide. Minimum wire gauge recom-
mendations for the individual ampli-
fiers are listed on the specification
page. Always use the same gauge
wire for the amplifier ground that
you use for the power wire. Be sure
to examine the battery ground

Prior to servicing your vehicle ensure
that the alarm system is ddiissaarrm

meedd. Due

to the amplifier’s anti-theft feature (if
enabled), if the main power to the

amplifier is removed while the alarm is
armed the amplifier operation is
disabled. The amplifier operation must
then be reset by your Directed dealer.
