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. 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
out 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. 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.
