TROUBLESHOOTING
Amplifier Does Not Turn On
Possible Cause
The
Poor ground connection
Poor power connection or power outside acceptable range.
Solution
Check
Verify that Ground connection is connected to clean metal on the vehicle’s chassis. Repair/replace if necessary.
Verify there is 10.5 - 15.5 Volts present at the positive battery and remote
No Sound Coming From Amplifier
Possible Cause
Poor RCA connections.
Solution
Verify good RCA input connections at source and amplifier. Check entire length of cables for kinks, splices, etc. Test RCA inputs for AC voltage with the source unit on. Repair/replace if necessary
Poor speaker connections
Bad source unit
Use an ohm meter to check speaker wire integrity. Check entire length of wires for kinks, splices, etc. Repair/replace if necessary.
Connect RCA input from test source directly to amplifier input. If this solves the problem, have the source unit repaired or replaced. If not, have the amplifier checked by a qualified technician.
Speaker "Pop" When Amplifier Turns On
Possible Cause
Remote from source unit comes on too quickly.
Poor remote power signal from source
Solution
Disconnect input signal to amplifier and turn amplifier on and off. If the noise is eliminated, connect the REM lead of amplifier to source unit with a delay
Use a different 12 Volt source for REM lead of amplifier (i.e. battery direct). If the noise is eliminated, use a relay to isolate the amplifier from noisy
Excessive Engine Noise
Possible Cause
RCA cables too close to main power cables.
Bad component in the signal chain
Poor ground connection at system components
Poor ground connection at battery
Solution
Route all signal carrying wires (RCA, Speaker cables) away from power and ground wires.
Bypass any and all electrical components between the source and the amplifier(s). Connect source directly to input of amplifier. If noise goes away the unit being bypassed is the cause of the noise.
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
Add secondary ground cable from negative battery terminal to the chassis metal or engine block of vehicle.
