Troubleshooting
If you are having problems after installation follow the
Troubleshooting procedures below.
Procedure 1: Check Amplifier for proper connections.
Verify that POWER light is on. If POWER light 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 of current present at the positive battery and
remote turn-on cable. Verify quality connections for both cables at amplifier,
stereo, and battery/fuseholder. Repair/replace if necessary.
Procedure 2: Check Amplifier for audio output.
1. Connect a single 4 or 8 ohm test speaker directly to each output channel
amplifier. Verify speakers in car are good and wiring between amplifier and
speakers, including connectors are good. Repair/replace if necessary.
2. Verify good RCA/high-level input connections at stereo and amplifier. Check
entire length of cables for kinks, splices, etc. Test RCA/high-level inputs for AC
current with stereo on. Repair/replace if necessary.
3. Disconnect RCA/high-level input from amplifier. Connect RCA/high-level input
from test stereo directly to amplifier input.
Procedure 3: Check Amplifier if you experience Turn-on Pop.
1. Disconnect input signal to amplifier and turn amplifier on and off.
2. If the noise is eliminated, connect the REM lead of amplifier to source unit with
a delay turn-on module.
OR
1. Use a different 12 Volt source for REM lead of amplifier (i.e. battery direct).
2. If the noise is eliminated, use a relay to isolate the amplifier from noisy turn-on
output.
Procedure 4: 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 stereo and the amplifi-
er(s). Connect stereo 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 work-
ing order of vehicle electrical system including distributor, spark plugs, spark
plug wires, voltage regulator etc.
