TROUBLESHOOTING

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 turn-on module

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 turn-on output.

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.

"WARNING: Amp is in Protection" Shows in READ Display

Possible Cause

There is a short in the system

Solution

Turn the system off. Check connection to all components for possible shorts. Check all wires and cables for kinks, splices, poor insulation, etc. Repair/replace if necessary.

Once the short is corrected, the amplifier should function normally. If the READ display still comes up with a warning, have the system checked by a qualified technician.

"THERMAL! (and temperature)" Shows in READ Display

Possible Cause

Amplifier has exceeded normal operating temperature due to improper ventilation.

Speaker impedance too low or set incorrectly.

Low battery voltage

Solution

Turn the system off and allow to cool. Verify adequate ventilation around amplifier. Move the amplifier to a spot with better ventilation if needed.

Check for proper speaker impedance, 2 (ohms) minimum, replace if needed. Check that the Impedance Switch matches the speaker impedance connected to the amplifier.

Check that the vehicle charging system is maintaining proper voltage.

If the READ display still comes up with THERMAL, have the system checked by a qualified technician.
