Troubleshooting Guide

Before you consult this listing, make sure the vehicle’s electrical system is working properly by verifying

that other electrical items (e. g. headlights, Windows, etc.) still function correctly.

SYMPTOM PROBABLE CAUSE SOLUTION

Low or N.C. remote turn-on connections

Check remote turn-on voltage at amp and head

unit

Blown fuse Replace with new fast-blow fuse

Power wires not connected

Check butt splices or solder joints;

Check ground and battery connections

No audio

Blown or non-speakers connected

Use VOM or DVM to measure speaker coil

impedance; check speaker wiring connections

Input sensitivity not set properly or

damaged speaker cones

See adjustment procedure and check each step;

inspect each speaker for damage and repair or

replace suspected component

Distorted audio

Low turn-on voltage Refer to head unit owner’s manual

Audio level low Mute circuits is on head unit

Check electrical system for low voltage;

Check ground connection

Audio lacks

Speakers wired with wrong polarity,

causing cancellation of bass frequencies

Check polarity of wires from amplifiers to each

speak as defined by the system design;

Check battery voltage at amplifier during

operation

External fuse

blowing

Incorrect wiring or short circuit

Refer to electrical installation and check each

installation step

Whining noise on

audio with engine

running

Amplifier is picking up alternator noise

Install a line noise filter on the head unit’s power

wire;

Check alternator routing diodes or voltage

regulator for proper operation. Check all

grounds, check battery voltage, check RCA

cables

Ticking noise on

audio with engine

running

Amplifier is peaking up radiated spark

noise

Check RCA audio cable; Install an in-line noise

filter on the head unit’s power wire, check spark

plug wires

Protection LED (right

color) light up when

the amplifier is

powered up

Incorrect impedance

Incorrect wiring or short circuit

Airflow around the amplifier is not

enough

Check if the minimum impedance is correct for

this model.

Check the speaker shots.

Check the airflow around the amplifier. More

space is required.
