Completing the Installation

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 side of the am-

plifier to its mid position (see “Adjusting the
Audio Level” on Page 13). 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” on Page 12.
