TESTING THE
CONNECTIONS
Before you continue, make sure you have
securely made all connections. Then recon-
nect the cable to the vehicle’s negative (
– )
battery terminal.
Set LEVEL (MIN/MAX) on the left and right
sides of the amplifier to its mid position (see
“Adjusting the Audio Level” on Page 18).
Then turn on your vehicle’s ignition and auto
sound system to confirm that the amplifier
and auto sound system operate properly.
The amplifier turns on after a few seconds.
If you cannot quickly confirm whether the
auto sound system and amplifier are working
properly, turn off your vehicle’s ignition
and disconnect the cable from your vehi-
cle’s negative (–) battery terminal. Then
recheck your connections.
After you test the auto sound system and
amplifier and verify that everything is proper-
ly connected and working, follow the instruc-
tions in “Mounting the Amplifier.”
MOUNTING THE AMPLIFIER
Once you verify that the amplifier is connect-
ed properly, follow these steps to mount it.
1. Disconnect the cable from the vehicle’s
negative (–) battery terminal.
2. To make mounting more convenient,
temporarily disconnect the amplifier’s
connections (ground, primary power,
remote power, your auto sound system’s
input, and speakers).
Note: If you have not already done so,
be sure to mark each wire with the name
of the terminal you will reconnect it to.
3. Using the mounting holes on the ampli-
fier as a guide, mark the positions for the
mounting holes.
4. Drill 9 /
64
-inch (3.57 mm) holes at the
marked locations, being careful not to
damage anything behind the mounting
surface.
