Problem
Amplifier will not play – Remote turn-on light is off.
Solution
1. Check the DC voltage at the amplifier's B+ terminal
with a voltmeter. The voltage should measure be-
tween 11.5V - 15.5V.
If voltage is not found, check the battery, fuse, fuse
housing and wire connections. Fix, repair, or replace
accordingly.
2. If the amplifier still does not play, check the voltage at
the amplifier's remote turn-on lead. The voltage should
measure between 11V - 15V.
a. If voltage is above or below the prescribed mea-
surements, have the head unit checked by an
Authorized Dealer or Service Center.
b. If the remote turn-on current draw from the head
unit is connected to multiple amps and/or electron-
ics, the current draw may be too great. Check for
proper connections. (Use a relay to suppress the
excessive current draw.)
If you are still having problems, have the amplifier checked
by an Authorized Rockford Fosgate Dealer.
Problem
Amplifier will not play – Remote turn-on light is on:
Solution
1. Unplug the head unit and test the amplifier with an-
other working source unit (i.e., bench-test radio,
walkman, etc.) If the amplifier plays, check the in-dash
leads for cuts, breaks and/or shorts.
2. If the amplifier still does not play, disconnect the
existing speakers and connect a set of test speakers
to the output of the amplifier (any type of speaker will
do - i.e., simple home box type, bookshelf, raw speaker,
etc.). If the amp plays, check for shorts or blown voice
coils in the vehicle's speaker system.
If you are still having problems, have the amplifier checked
out by an Authorized Rockford Fosgate Dealer.
