ROUBLESHOOTING
NOTE: If you are having problems after installation follow the Troubleshooting procedures below.
If the display reads "Memory Error" or is difficult to read, see Display Problems at bottom.
Procedure 1: Check Amplifier for proper connections.
Verify that the LCD Display comes on. If it is on, skip to Step 2, if not continue.
1. Check in-line fuse on battery positive cable. Replace if necessary.
2. Verify that Ground connection is connected to clean metal of the vehicle’s chassis.
Repair/replace if necessary.
3. Verify there is 10.5 - 15.5 Volts present at the positive battery and remote turn-on cable. Verify
quality connections for both cables at amplifier, source unit, and battery/fuseholder.
Repair/replace if necessary.
Procedure 2: Check Amplifier for audio output.
1. Verify good RCA input connections at source unit and amplifier. Check entire length of cables
for kinks, splices, etc. Test RCA inputs for AC current with source unit on. Repair/replace if
necessary.
2. Disconnect RCA input from amplifier. Connect RCA input from test source unit directly to
amplifier input.
Procedure 3: Check Amplifier if you experience excess Engine Noise.
1. Route all signal carrying wires (RCA, Speaker cables) away from power and ground wires.
OR
2. Bypass any and all electrical components between the source unit and the amplifier(s). Connect
source unit directly to input of amplifier. If noise goes away the unit being bypassed is the cause
of the noise.
OR
3. Remove existing ground wires for all electrical components. Reground wires to different
locations. Verify that grounding location is clean, shiny metal free of paint, rust etc.
OR
4. Add secondary ground cable from negative battery terminal to the chassis metal or engine block
of vehicle.
OR
5. Have alternator and battery load tested by your mechanic. Verify good working order of vehicle
electrical system including distributor, spark plugs, spark plug wires, voltage regulator etc.
DISPLAY PROBLEMS
Display hard to read: Insert a small flat bladed screwdriver into the hole above the display screen.
While viewing the display, turn the adjuster either way until the display is easily visible.
Display reads "Memory Error": If this occurs, the current settings in the amplifier will automatically
reset to the factory defaults except for the INPUT LEVEL, which will set to Ø (mute) to protect the
system components. Readjust the amplifier settings and then reset the INPUT LEVEL as needed
before operating the amplifier. If the memory error still occurs after readjusting and saving settings,
contact Rockford Technical Support. Settings saved in GLOBAL SAVE will not be affected.
